Running ASP Net on a Linux based server

Question

For a developer with a Java background  I am interested in exploring software development using the ASP NET tools platform as well    Java web applications   jsp and servlets  can run on many server platforms   Question  Will a  NET web application be able to run in a Linux based server  Considering the scenario of not being able to use a Windows server for hosting a web app

So I know this is an older question but I think it could stand an updated answer.

Microsoft has officially released asp.net vnext and its open source and deploy-able to both Linux and Mac. Its all still pretty new but does rely on the latest builds of mono and thus currently needs you to compile the mono-framework but in time I suspect that it will be easier to access as various linux distros release updated versions of mono. This is a how to setup guide

This information may be somewhat volatile and with updates is due to change.

Update ASP.NET CORE 11/10/2017

asp.net vnext is now known as asp.net core.
asp.net core is being treated as a high priority in Microsoft due in part to its use with microservice architecture and docker and container technologies
It has become much more compatible with existing .net libraries due to .net standard 2.0.
It performs well when compared to other technology stacks such as go and node.js

Now you can publish ASP NET 5 app to Docker on Linux with Visual Studio  See the below post from Scott Haselman  http   www hanselman com blog PublishingAnASPNET5AppToDockerOnLinuxWithVisualStudio aspx

It depends what specific  NET technologies you re using   The Mono Project provides an Apache module  mod mono  for running ASP NET sites  and from what I gather it works well     Mono doesn t support all the  NET APIs  though - notably WPF  and possibly WCF too  I can t remember  - but it does provide good support for much else of the framework     If you re starting from scratch and particularly want to target non-Windows servers  then ensuring your project works with Mono would be a good goal to aim for   However  if you need particular APIs or language features that are not supported by Mono  then you will need to use a Windows server for deployment   It s a design-time architectural choice that should make up front

Since the technologies evolve and this question is top ranked in google  we need to include beyond the mono the new asp net core  which is a complete rewrite of the asp net to run for production in Linux and Windows and for development for Linux  Windows and Mac      You can develop and run your ASP NET Core apps cross-platform on   Windows  Mac and Linux  ASP NET Core is open source at GitHub

Now a days  Net is run in multiple platforms like linux  Mac os etc  but mono is not fully platform independent  Because to deploy  NET in another OS required  third party software so it is not like java platform independent   Mono is running in different platform  because of JIT is there in different os   Mono is not fully success in moonlight silver light in  NET   Not only Research is going on   Mono uses XSP2 server or apache   some of the big companies are using this project Some of the robotic project are also running on mono   For more details  http   www mono-project com Main Page

I can speak from experience  Even if your ASP net website only uses  NET libraries supported by Mono you are going to have a hard time getting it to run if its anything beyond Hello World   You won t have to re-write much code but you will spend hours days weeks dealing with little issues with mod mono xsp apache configuration and file permissions and error handling and all the little things that go into a large website   Be prepared to spend a lot of time asking questions on serverfault       The problem is that a lot of people don t use Mono for ASP net websites and so there aren t as many people reporting bugs so a lot of things that are minor bugs go un-fixed for a long time

dotnet is the official home of  NET on GitHub  It s a great starting point to find many  NET OSS projects from Microsoft and the community  including many that are part of the  NET Foundation   This may be a great start to support Linux

You can use Mono to run ASP NET applications on Apache Linux  however it has a limited subset of what you can do under Windows  As for  they  saying Windows is more vulnerable to attack - it s not true  IIS has had less security problems over the last couple of years that Apache  but in either case it s all down to the administration of the boxes - both OSes can be easily secured  These days the attack points are not the OS or web server software  but the applications themselves

There is the Mono Project from Novell that will allow you to run ASP Net on Apache   http   www mono-project com Main Page

For ASP NET on Linux  check out Mono   That said  thousands of sites run on Windows Server without any issues  A poorly-configured server with any OS will be vulnerable  Linux won t save you from a poor admin   So I guess my  best practice  for deplying an ASP NET app would be to use Windows Server 2008  likely Web edition   And hire a good administrator

The Mono project is your best option  However  it has a lot of pitfalls  like incomplete API support in some areas   and it s legally gray  people like Richard Stallman have derided the use of Mono because of the possibility of Microsoft coming down on Mono by using its patent rights  but that s another story    Anyway  Apache supports  NET Mono through a module  but the last time I checked the version supplied with Debian  it gave Perl language support only  I can t say if it s changed since  perhaps someone else can correct me there
