NET Core vs Mono

Question

What is the difference between  NET Core and Mono   I found a statement on the official site that said   Code written for it is also portable across application stacks  such as Mono    My goal is to use C   LINQ  EF7 and Visual Studio to create a website that can be ran hosted on Linux   Someone told me that he wanted it to be  in Mono   but I don t know what that means  I know I want to use the  NET Core 1 0 with the technologies I listed above  He also said he wanted to use  fast CGI   I don t know what that means either   Can you help me make sense of all these terms and if my expectations are realistic

This question is especially actual because yesterday Microsoft officially announced .NET Core 1.0 release. Assuming that Mono implements most of the standard .NET libraries, the difference between Mono and .NET core can be seen through the difference between .NET Framework and .NET Core:

APIs — .NET Core contains many of the same, but fewer, APIs as the .NET Framework, and with a different factoring (assembly names are
different; type shape differs in key cases). These differences
currently typically require changes to port source to .NET Core. .NET Core implements the .NET Standard Library API, which will grow to
include more of the .NET Framework BCL APIs over time.

Subsystems — .NET Core implements a subset of the subsystems in the .NET Framework, with the goal of a simpler implementation and
programming model. For example, Code Access Security (CAS) is not
supported, while reflection is supported.

If you need to launch something quickly, go with Mono because it is currently (June 2016) more mature product, but if you are building a long-term website, I would suggest .NET Core. It is officially supported by Microsoft and the difference in supported APIs will probably disappear soon, taking into account the effort that Microsoft puts in the development of .NET Core.

My goal is to use C#, LINQ, EF7, visual studio to create a website that can be ran/hosted in linux.

Linq and Entity framework are included in .NET Core, so you are safe to take a shot.

This is no more  NET Core vs  Mono  It s unified  Update as of November 2020 -  NET 5 released that unifies  NET Framework and  NET Core  NET and Mono will be unified under  NET 6 that would be released in November 2021   NET 6 0 will add net6 0-ios and net6 0-android  The OS-specific names can include OS version numbers  like net6 0-ios14   Check below articles   https   devblogs microsoft com dotnet introducing-net-multi-platform-app-ui  https   github com dotnet maui

To be simple       Mono is third party implementation of  Net framework for   Linux Android iOs       Net Core is microsoft s own implementation for same     Net Core is future  and Mono will be dead eventually  Having said that  Net Core is not matured enough  I was struggling to implement it with IBM Bluemix and later dropped the idea  Down the time  may be 1-2 years   it should be better

Necromancing   Providing an actual answer      What is the difference between  Net Core and Mono     NET Core now officially is the future of  NET  It started for most part with a re-write of the ASP NET MVC framework and console applications  which of course includes server applications   Since it s Turing-complete and supports interop with C dlls  you could  if you absolutely wanted to  also write your own desktop applications with it  for example through 3rd-party libraries like Avalonia  which were a bit very basic at the time I first wrote this  which meant you were pretty much limited to web or server stuff   Over time  many APIs have been added to  NET Core  so much so that after version 3 1   NET Core will jump to version 5 0  be known as  NET 5 0 without the  Core   and that then will be the future of the  NET Framework  What used to be the full  NET Framework will linger around in maintenance mode as Full  NET Framework 4 8 x for a few decades  until it will die  maybe there are still going to be some upgrades  but I doubt it   In other words   NET Core is the future of  NET  and Full  NET Framework will go the way of the Dodo Silverlight WindowsPhone    The main point of  NET Core  apart from multi-platform support  is to improve performance  and to enable  native compilation  self-contained-deployment  so you don t need  NET framework VM installed on the target machine   On the one hand  this means docker io support on Linux  and on the other  self-contained deployment is useful in  cloud-computing   since then you can just use whatever version of the dotnet-CORE framework you like  and you don t have to worry about which version s  of the  NET framework the sysadmin has actually installed   While the  NET Core runtime supports multiple operating systems and processors  the SDK is a different story  And while the SDK supports multiple OS  ARM support for the SDK is was still work in progress   NET Core is supported by Microsoft  Dotnet-Core did not come with WinForms or WPF or anything like that     As of version 3 0  WinForms and WPF is also supported by  NET Core  but only on Windows  and only by C   Not by VB NET  VB NET support planned for v5 in 2020   And there is no Forms Designer in  NET Core  it s being shipped with a Visual Studio update later  at an  unspecified time   WebForms are still not supported by  NET Core  and there are no plans to support them  ever  Blazor is the new kid in town for that     NET Core also comes with System Runtime  which replaces mscorelib  Oftentimes   NET Core is mixed up with NetStandard  which is a bit of a wrapper around System Runtime mscorelib  and some others   that allows you to write libraries that target  NET Core  Full  NET Framework and Xamarin  iOS Android   all at the same time  the  NET Core SDK does not did not work on ARM  at least not last time I checked     The Mono Project  is much older than  NET Core  Mono is Spanish and means Monkey  and as a side-remark  the name has nothing to do with mononucleosis  hint  you could get a list of staff under http   primates ximian com    Mono was started in 2005 by Miguel de Icaza  the guy that started GNOME - and a few others  as an implementation of the  NET Framework for Linux  Ximian SuSe Novell   Mono includes Web-Forms  Winforms  MVC  Olive  and an IDE called MonoDevelop  also knows as Xamarin Studio or Visual Studio Mac   Basically the equivalent of  OpenJDK  JVM and  OpenJDK  JDK JRE  as opposed to SUN Oracle JDK   You can use it to get ASP NET-WebForms   WinForms   ASP NET-MVC applications to work on Linux  Mono is supported by Xamarin  the new company name of what used to be Ximian  when they focused on the Mobile market  instead of the Linux market   and not by Microsoft   since Xamarin was bought by Microsoft  that s technically  but not culturally   Microsoft   You will usually get your C  stuff to compile on mono  but not the VB NET stuff   Mono misses some advanced features  like WSE WCF and WebParts  Many of the Mono implementations are incomplete  e g  throw NotImplementedException in ECDSA encryption   buggy  e g  ODBC ADO NET with Firebird   behave differently than on  NET  for example XML-serialization  or otherwise unstable  ASP NET MVC  and unacceptably slow  Regex   On the upside  the Mono toolchain also works on ARM   As far as  NET Core is concerned  when they say cross-platform  don t expect that cross-platform means that you could actually just apt-get install  NET Core on ARM-Linux  like you can with ElasticSearch  You ll have to compile the entire framework from source  That is  if you have that space  e g  on a Chromebook  which has a 16 to 32 GB total HD   It also used to have issues of incompatibility with OpenSSL 1 1 and libcurl  Those have been rectified in the latest version of  NET Core Version 2 2  So much for cross-platform      I found a statement on the official site that said   Code written for   it is also portable across application stacks  such as Mono     As long as that code doesn t rely on WinAPI-calls  Windows-dll-pinvokes  COM-Components  a case-insensitive file system  the default-system-encoding  codepage  and doesn t have directory separator issues  that s correct  However   NET Core code runs on  NET Core  and not on Mono  So mixing the two will be difficult  And since Mono is quite unstable and slow  for web applications   I wouldn t recommend it anyway  Try image-processing on  NET core  e g  WebP or moving GIF or multipage-tiff or writing text on an image  you ll be nastily surprised       Note     As of  NET Core 2 0  there is System Drawing Common  NuGet   which   contains most of the functionality of System Drawing  It should be   more or less feature-complete in  NET-Core 2 1  However    System Drawing Common uses GDI   and therefore won t work on Azure    System Drawing libraries are available in Azure Cloud Service    basically just a VM   but not in Azure Web App  basically shared   hosting      So far  System Drawing Common works fine on Linux Mac  but has issues on iOS Android - if it works at all  there     Prior to  NET Core 2 0  that is to say sometime mid-February 2017  you could use SkiaSharp for imaging  example   you still can   Post  net-core 2 0  you ll notice that SixLabors ImageSharp is the way to go  since System Drawing is not necessarely secure  and has a lot of potential or real memory leaks  which is why you shouldn t use GDI in web-applications  Note that SkiaSharp is a lot faster than ImageSharp  because it uses native-libraries  which can also be a drawback   Also  note that while GDI  works on Linux  amp  Mac  that doesn t mean it works on iOS Android     Code not written for  NET  non-Core  is not portable to  NET Core  Meaning  if you want a non-GPL C  library like PDFSharp to create PDF-documents  very commonplace   you re out of luck  at the moment   not anymore   Never mind ReportViewer control  which uses Windows-pInvokes  to encrypt  create mcdf documents via COM  and to get font  character  kerning  font embedding information  measure strings and do line-breaking  and for actually drawing tiffs of acceptable quality   and doesn t even run on Mono on Linux  I m working on that     Also  code written in  NET Core is not portable to Mono  because Mono lacks the  NET Core runtime libraries  so far        My goal is to use C   LINQ  EF7  visual studio to create a website   that can be ran hosted in linux    EF in any version that I tried so far was so goddamn slow  even on such simple things like one table with one left-join   I wouldn t recommend it ever - not on Windows either   I would particularly not recommend EF if you have a database with unique-constrains  or varbinary filestream hierarchyid columns   Not for schema-update either   And also not in a situation where DB-performance is critical  say 10  to 100  concurrent users   Also  running a website web-application on Linux will sooner or later mean you ll have to debug it  There is no debugging support for  NET Core on Linux   Not anymore  but requires JetBrains Rider   MonoDevelop does not  yet  support debugging  NET Core projects  If you have problems  you re on your own  You ll have to use extensive logging  Be careful  be advised extensive logging will fill your disk in no time  particularly if your program enters an infinite loop or recursion  This is especially dangerous if your web-app runs as root  because log-in requires logfile-space - if there s no free space left  you won t be able to login anymore    Normally  about 5  of diskspace is reserved for user root  aka administrator on Windows   so at least the administrator can still log in if the disk is almost full  But if your applications run as root  that restriction does not apply for their disk usage  and so their logfiles can use 100  of the remaining free space  so not even the administrator can log in any more   It s therefore better not to encrypt that disk  that is  if you value your data system       Someone told me that he wanted it to be  in Mono   but I don t know   what that means    It either means he doesn t want to use  NET Core  or he just wants to use C  on Linux Mac  My guess is he just wants to use C  for a Web-App on Linux   NET Core is the way to go for that  if you absolutely want to do it in C   Don t go with  Mono proper   on the surface  it would seem to work at first - but believe me you will regret it because Mono s ASP NET MVC isn t stable when your server runs long-term  longer than 1 day  - you have now been warned  See also the  did not complete  references when measuring Mono performance on the techempower benchmarks         I know I want to use the  Net Core 1 0 framework with the technologies   I listed above  He also said he wanted to use  fast cgi   I don t know   what that means either    It means he wants to use a high-performance full-featured WebServer like nginx  Engine-X   possibly Apache   Then he can run mono dotnetCore with virtual name based hosting  multiple domain names on the same IP  and or load-balancing  He can also run other websites with other technologies  without requiring a different port-number on the web-server  It means your website runs on a fastcgi-server  and nginx forwards all web-requests for a certain domain via the fastcgi-protocol to that server  It also means your website runs in a fastcgi-pipeline  and you have to be careful what you do  e g  you can t use HTTP 1 1 when transmitting files  Otherwise  files will be garbled at the destination   See also here and here   To conclude   NET Core at present  2016-09-28  is not really portable  nor is is really cross-platform  in particular the debug-tools    Nor is native-compilation easy  especially for ARM  And to me  it also does not look like its development is  really finished   yet   For example  System Data DataTable DataAdaper Update is missing        not anymore with  NET Core 2 0  Together with the System Data Common IDB  interfaces   not anymore with  NET Core 1 1  if there ever was one class that is often used  DataTable DataAdapter would be it     Also  the Linux-installer   deb  fails  at least on my machine  and I m sure I m not the only one that has that problem   Debug  maybe with Visual Studio Code  if you can build it on ARM  I managed to do that - do NOT follow Scott Hanselman s blog-post if you do that - there s a howto in the wiki of VS-Code on github   because they don t offer the executable   Yeoman also fails   I guess it has something to do with the nodejs version you installed - VS Code requires one version  Yeoman another    but it should run on the same computer  pretty lame Never mind that it should run on the node version shipped by default on the OS   Never mind that there should be no dependency on NodeJS in the first place   The kestell server is also work in progress   And judging by my experience with the mono-project  I highly doubt they ever tested  NET Core on FastCGI  or that they have any idea what FastCGI-support means for their framework  let alone that they tested it to make sure  everything works   In fact  I just tried making a fastcgi-application with  NET Core and just realized there is no FastCGI library for  NET Core  RTM      So when you re going to run  NET Core  RTM  behind nginx  you can only do it by proxying requests to kestrell  that semi-finished nodeJS-derived web-server  - there s no fastcgi support at present in  NET Core  RTM   AFAIK  Since there is no  net core fastcgi library  and no samples  it s also highly unlikely that anybody did any testing on the framework to make sure fastcgi works as expected   I also question the performance   In the  preliminary  techempower-benchmark  round 13   aspnetcore-linux ranks on 25  relative to the best performance  while comparable frameworks like Go  golang  rank at 96 9  of peak performance  and that is when returning plaintext without file-system access only    NET Core does a little better on JSON-serialization  but it does not look compelling either  go reaches 98 5  of peak   NET core 65    That said  it can t possibly be worse than  mono proper     Also  since it s still relatively new  not all of the major libraries have been ported  yet   and I doubt that some of them will ever be ported   Imaging support is also questionable at best   For anything encryption  use BouncyCastle instead       Can you help me make sense of all these terms and if my expectations   are realistic    I hope i helped you making more sense with all these terms   As far as your expecations go  Developing a Linux application without knowing anything about Linux is a really stupid idea in the first place  and it s also bound to fail in some horrible way one way or the other  That said  because Linux comes at no licensing costs  it s a good idea in principle  BUT ONLY IF YOU KNOW WHAT YOU DO   Developing an application for a platform where you can t debug your application on is another really bad idea   Developing for fastcgi without knowing what consequences there are is yet another really bad idea    Doing all these things on a  experimental  platform without any knowledge of that platform s specifics and without debugging support is suicide  if your project is more than just a personal homepage  On the other hand  I guess doing it with your personal homepage for learning purposes would probably be a very good experience - then you get to know what the framework and what the non-framework problems are   You can for example  programmatically  loop-mount a case-insensitive fat32  hfs or JFS for your application  to get around the case-sensitivity issues  loop-mount not recommended in production    To summarize At present  2016-09-28   I would stay away from  NET Core  for production usage   Maybe in one to two years  you can take another look  but probably not before  If you have a new web-project that you develop  start it in  NET Core  not mono  If you want a framework that works on Linux  x86 AMD64 ARMhf  and Windows and Mac  that has no dependencies  i e  only static linking and no dependency on  NET  Java or Windows  use Golang instead  It s more mature  and its performance is proven  Baidu uses it with 1 million concurrent users   and golang has a significantly lower memory footprint  Also golang is in the repositories  the  deb installs without problems  the sourcecode compiles - without requiring changes - and golang  in the meantime  has debugging support with delve and JetBrains Gogland on Linux  and Windows and Mac   Golang s build process  and runtime  also doesn t depend on NodeJS  which is yet another plus    As far as mono goes  stay away from it   It is nothing short of amazing how far mono has come  but unfortunately that s no substitute for its performance scalability and stability issues for production applications   Also  mono-development is quite dead  they largely only develop the parts relevant to  Android and iOS anymore  because that s where Xamarin makes their money  Don t expect Web-Development to be a first-class Xamarin mono citizen    NET Core might be worth it  if you start a new project  but for existing large web-forms projects  porting over is largely out of the question  the changes required are huge  If you have a MVC-project  the amount of changes might be manageable  if your original application design was sane  which is mostly not the case for most existing so-called  historically grown  applications   December 2016 Update  Native compilation has been removed from  NET Core preview  as it is not yet ready     Seems like they have improved pretty heavily on the raw text-file benchmark  but on the other hand  it s gotten pretty buggy  Also  it further deteriorated in the JSON benchmarks  Curious also that entity framework shall be faster for updates than Dapper - although both at record slowness  This is very unlikely to be true  Looks like there still are more than just a few bugs to hunt    Also  there seems to be relief coming on the Linux IDE front   JetBrains released  Project Rider   an early access preview of a C   NET Core IDE for Linux  and Mac and Windows   that can handle Visual Studio Project files   Finally a C  IDE that is usable  amp  that isn t slow as hell    Conclusion   NET Core still is pre-release quality software as we march into 2017  Port your libraries  but stay away from it for production usage  until framework quality stabilizes   And keep an eye on Project Rider     2017 Update Have migrated my  brother s  homepage to  NET Core for now  So far  the runtime on Linux seems to be stable enough  at least for small projects  - it survived a load test with ease - mono never did  Also  it looks like I mixed up  NET-Core-native and  NET-Core-self-contained-deployment  Self-contained deployment works  but it is a bit underdocumented  although it s super easy  the build publish tools are a bit unstable  yet - if you encounter  Positive number required  - Build FAILED   - run the same command again  and it works    You can run  dotnet restore -r win81-x64 dotnet build -r win81-x64 dotnet publish -f netcoreapp1 1 -c Release -r win81-x64      Note  As per  NET Core 3  you can publish everything minified as a single file    dotnet publish -r win-x64 -c Release  p PublishSingleFile true dotnet publish -r linux-x64 -c Release  p PublishSingleFile true      However  unlike go  it s not a statically linked executable  but a self-extracting zip file  so when deploying  you might run into   problems  especially if the temp directory is locked down by group   policy  or some other issues  Works fine for a   hello-world program  though  And if you don t minify  the executable size will clock in at something around 100 MB     And you get a self-contained  exe-file  in the publish directory   which you can move to a Windows 8 1 machine without  NET framework installed and let it run  Nice  It s here that dotNET-Core just starts to get interesting   mind the gaps  SkiaSharp doesn t work on Windows 8 1   Windows Server 2012 R2   yet  - the ecosystem has to catch up first - but interestingly  the Skia-dll-load-fail doesn t crash the entire server application - so everything else works    Note  SkiaSharp on Windows 8 1 is missing the appropriate VC runtime files - msvcp140 dll and vcruntime140 dll  Copy them into the publish-directory  and Skia will work on Windows 8 1    August 2017 Update  NET Core 2 0 released   Be careful - comes with  huge breaking  changes in authentication    On the upside  it brought the DataTable DataAdaper DataSet classes back  and many more  Realized  NET Core is still missing support for Apache SparkSQL  because Mobius isn t yet ported  That s bad  because that means no SparkSQL support for my IoT Cassandra Cluster  so no joins    Experimental ARM support  runtime only  not SDK - too bad for devwork on my Chromebook - looking forward to 2 1 or 3 0    PdfSharp is now experimentally ported to  NET Core  JetBrains Rider left EAP  You can now use it to develop  amp  debug  NET Core on Linux - though so far only  NET Core 1 1 until the update for  NET Core 2 0 support goes live   May 2018 Update  NET Core 2 1 release imminent   Maybe this will fix NTLM-authentication on Linux  NTLM authentication doesn t work on Linux  and possibly Mac  in  NET-Core 2 0 with multiple authenticate headers  such as negotiate  commonly sent with ms-exchange  and they re apparently only fixing it in v2 1  no bugfix release for 2 0    But I m not installing preview releases on my machine  So waiting   v2 1 is also said to greatly reduce compile times  That would be good   Also  note that on Linux   NET Core is 64-Bit only    There is no  and there will be no  x86-32 version of  NET Core on Linux  And the ARM port is ARM-32 only  No ARM-64  yet  And on ARM  you  at present  only have the runtime  not the dotnet-SDK   And one more thing   Because  NET-Core uses OpenSSL 1 0   NET Core on Linux doesn t run on Arch Linux  and by derivation not on Manjaro  the most popular Linux distro by far at this point in time   because Arch Linux uses OpenSSL 1 1  So if you re using Arch Linux  you re out of luck  with Gentoo  too     Edit       Latest version of  NET Core 2 2  supports OpenSSL 1 1  So you can use   it on Arch or  k Ubuntu 19 04   You might have to use the  NET-Core   install script though  because there are no packages  yet    On the upside  performance has definitely improved        NET Core 3    NET-Core v 3 0 is said to bring WinForms and WPF to  NET-Core   However  while WinForms and WPF will be  NET Core  WinForms and WPF in  NET-Core will run on Windows only  because WinForms WPF will use the Windows-API    Note   NET Core 3 0 is now out  RTM   and there is WinForms and WPF support  but only for C   on Windows   There is no WinForms-Core-Designer  The designer will  eventually  come with a Visual Studio update  somewhen  WinForms support for VB NET is not supported  but is planned for  NET 5 0 somewhen in 2020    PS    echo  DOTNET CLI TELEMETRY OPTOUT 1   gt  gt   etc environment export DOTNET CLI TELEMETRY OPTOUT 1    If you ve used it on windows  you probably never saw this      The  NET Core tools collect usage data in order to improve your   experience  The data is anonymous and does not include command-line   arguments  The data is collected by Microsoft and shared with the   community  You can opt out of telemetry by setting a   DOTNET CLI TELEMETRY OPTOUT environment variable to 1 using your   favorite shell  You can read more about  NET Core tools telemetry     https   aka ms dotnet-cli-telemetry    I thought I d mention that I think monodevelop  aka Xamarin Studio  the Mono IDE  or Visual Studio Mac as it is now called on Mac  has evolved quite nicely  and is - in the meantime - largely usable   However  JetBrains Rider  2018 EAP at this point in time  is definitely a lot nicer and more reliable  and the included decompiler is a life-safer   that is to say  if you develop  NET-Core on Linux or Mac  MonoDevelop does not support Debug-StepThrough on Linux in  NET Core  though  since MS does not license their debugging API dll  except for VisualStudio Mac        However  you can use the Samsung debugger for  NET Core through the  NET Core debugger extension for Samsung Debugger for MonoDevelop  Disclaimer   I don t use Mac  so I can t say if what I wrote here applies to FreeBSD-Unix based Mac as well  I am refering to the Linux  Debian Ubuntu Mint  version of JetBrains Rider  mono  MonoDevelop VisualStudioMac XamarinStudio and  NET-Core  Also  Apple is contemplating a move from Intel-processors to self-manufactured ARM ARM-64  -based processors  so much of what applies to Mac right now might not apply to Mac in the future  2020      Also  when I write  mono is quite unstable and slow   the unstable relates to WinFroms  amp  WebForms applications  specifically executing web-applications via fastcgi or with XSP  on the 4 x version of mono   as well as XML-serialization-handling peculiarities  and the quite-slow relates to WinForms  and regular expressions in particular  ASP NET-MVC uses regular expressions for routing as well     When I write about my experience about mono 2 x  3 x and 4 x  that also does not necessarely mean these issues haven t been resolved by now  or by the time you are reading this  nor that if they are fixed now  that there can t be a regression later that reintroduces any of these bugs features  Nor does that mean that if you embed the mono-runtime  you ll get the same results as when you use the  dev  system s mono runtime  It also doesn t mean that embedding the mono-runtime  anywhere  is necessarely free    All that doesn t necessarely mean mono is ill-suited for iOS or Android  or that it has the same issues there  I don t use mono on Android or IOS  so I m in no positon to say anything about stability  usability  costs and performance on these platforms  Obviously  if you use  NET on Android  you have some other costs considerations to do as well  such as weighting xamarin-costs vs  costs and time for porting existing code to Java  One hears mono on Android and IOS shall be quite good  Take it with a grain of salt  For one  don t expect the default-system-encoding to be the same on android ios vs  Windows  and don t expect the android filesystem to be case-insensitive  and don t expect any windows fonts to be present

In the  NET world there are two types of CLRs   full  CLRs and Core CLRs  and these are quite different things   There are two  full  CLR implementations  the Microsoft native  NET CLR  for Windows  and the Mono CLR  which itself has implementations for Windows  linux and unix  Mac OS X and FreeBSD    A full CLR is exactly that - everything  pretty much  that you need  As such   full  CLRs tend to be large in size   Core CLRs are on the other hand are cut down  and much smaller  Because they are only a core implementation  they are unlikely to have everything you need in them  so with Core CLRs you add feature sets to the CLR that your specific software product uses  using NuGet  There are Core CLR implementations for Windows  linux  various  and unix  Mac OS X and FreeBSD  in the mix  Microsoft have or are refactoring the  NET framework libraries for Core CLR too  to make them more portable for the core context  Given mono s presence on  nix OSs it would be a surprise if the Core CLRs for  nix did not include some mono code base  but only the Mono community and Microsoft could tell us that for sure   Also  I d concur with Nico in that Core CLRs are new -- it s at RC2 at the moment I think  I wouldn t depend on it for production code yet   To answer your question you could delivery your site on linux using Core CLR or Mono  and these are two different ways of doing it  If you want a safe bet right now I d go with mono on linux  then port if you want to later  to Core

This is one of my favorite topics and the content here was just amazing  I was thinking if it would be worth while or effective to compare the methods available in Runtime vs  Mono  I hope I got my terms right  but I think you know what I mean  In order to have a somewhat better understanding of what each Runtime supports currently  would it make sense to compare the methods they provide  I realize implementations may vary  and I have not considered the Framework Class libraries or the slew of other libraries available in one environment vs  the other  I also realize someone might have already done this work even more efficiently  I would be most grateful if you would let me know so I can review it  I feel doing a diff between the outcome of such activity would be of value  and wanted to see how more experienced developers feel about it  and would they provide useful guidance  While back I was playing with reflection  and wrote some lines that traverse the  net directory  and list the assemblies

Net Core does not require mono in the sense of the mono framework   Net Core is a framework that will work on multiple platforms including Linux  Reference https   dotnet github io    However the  Net core can use the mono framework  Reference https   docs asp net en 1 0 0-rc1 getting-started choosing-the-right-dotnet html   note rc1 documentatiopn no rc2 available   however mono is not a Microsoft supported framework and would recommend using a supported framework   Now entity framework 7 is now called Entity Framework Core and is available on multiple platforms including Linux  Reference https   github com aspnet EntityFramework  review the road map   I am currently using both of these frameworks however you must understand that it is still in release candidate stage  RC2 is the current version  and over the beta  amp  release candidates there have been massive changes that usually end up with you scratching your head   Here is a tutorial on how to install MVC  Net Core into Linux  https   docs asp net en 1 0 0-rc1 getting-started installing-on-linux html  Finally you have a choice of Web Servers  where I am assuming the fast cgi reference came from  to host your application on Linux  Here is a reference point for installing to a Linux enviroment  https   docs asp net en 1 0 0-rc1 publishing linuxproduction html  I realise this post ends up being mostly links to documentation but at this point those are your best sources of information   Net core is still relatively new in the  Net community and until its fully released I would be hesitant to use it in a product environment given the breaking changes between released version

You have chosen not only a realistic path  but arguably one of the best ecosystems strongly backed also X-platforms  by MS  Still you should consider following points    Update  Main doc about  Net platform standard is here  https   github com dotnet corefx blob master Documentation architecture net-platform-standard md  Update  Current Mono 4 4 1 cannot run latest Asp Net core 1 0 RTM Although mono is more feature complete  its future is unclear  because MS owns it for some months now and its a duplicate work for them to support it  But MS is definitely committed to  Net Core and betting big on it  Although  Net core is released  the 3rd party ecosystem is not quite there  For example Nhibernate  Umbraco etc cannot run over  Net core yet  But they have a plan  There are some features missing in  Net Core like System Drawing  you should look for 3rd party libraries You should use nginx as front server with kestrelserver for asp net apps  because kestrelserver is not quite ready for production  For example HTTP 2 is not implemented    I hope it helps
