What s the difference between NET Core NET Framework and Xamarin

Question

Microsoft now has  NET Core   NET Framework and Xamarin  Mono  in its family  It seems to be a lot of overlap here  What s the difference between these types of  NET Platforms  When should I choose to use  NET Core in my project  instead of  NET Framework or Xamarin

Xamarin is used for phone applications  both IOS Android   The  NET Core is used for designing Web applications that can work on both Apache and IIS    That is the difference in two sentences

NET 5 will be a unified version of all  NET variants coming in November 2020  so there will be no need to choose between variants anymore

NET is the Ecosystem based on c  language  NET Standard  is Standard  in other words  specification  of  NET Ecosystem         Net Core Class Library is built upon the  Net Standard     NET Standard you can make only class-library project that cannot be executed standalone and should be referenced by another  NET Core or  NET Framework executable project If you want to implement a library that is portable to the  Net Framework   Net Core and Xamarin  choose a  Net Standard Library     NET Framework is a framework based on  NET and it supports Windows and Web applications       You can make executable project  like Console application  or ASP NET application  with  NET Framework    ASP NET is a web application development technology which is built over the  NET Framework  NET Core also a framework based on  NET       It is the new open-source and cross-platform framework to build applications for all operating system including Windows  Mac  and Linux     Xamarin is a framework to develop a cross platform mobile application iOS  Android  and Windows Mobile  using C        Implementation support of  NET Standard blue  and minimum viable platform for full support of  NET Standard  latest   https   docs microsoft com en-us dotnet standard net-standard net-implementation-support

This is how Microsoft explains it      NET Framework is the  full  or  traditional  flavor of  NET that s distributed with Windows  Use this when you are building a desktop Windows or UWP app  or working with older ASP NET 4 6      NET Core is cross-platform  NET that runs on Windows  Mac  and Linux  Use this when you want to build console or web apps that can run on any platform  including inside Docker containers  This does not include UWP desktop apps currently   Xamarin is used for building mobile apps that can run on iOS  Android  or Windows Phone devices   Xamarin usually runs on top of Mono  which is a version of  NET that was built for cross-platform support before Microsoft decided to officially go cross-platform with  NET Core  Like Xamarin  the Unity platform also runs on top of Mono     A common point of confusion is where ASP NET Core fits in  ASP NET Core can run on top of either  NET Framework  Windows  or  NET Core  cross-platform   as detailed in this answer  Difference between ASP NET Core   NET Core  and ASP NET Core   NET Framework

NET Core is the current version of  NET that you should be using right now  more features   fixed bugs   etc    Xamarin is a platform that provides solutions for cross platform mobile problems coded in C    so that you don t need to use Swift separately for IOS and the same goes for Android

You should use  NET Core  instead of  NET Framework or Xamarin  in the following 6 typical scenarios according to the documentation here   1  Cross-Platform needs Clearly  if your goal is to have an application  web service  that should be able to run across platforms  Windows  Linux and MacOS   the best choice in the  NET ecosystem is to use  NET Core as its runtime  CoreCLR  and libraries are cross-platform  The other choice is to use the Mono Project  Both choices are open source  but  NET Core is directly and officially supported by Microsoft and will have a heavy investment moving forward  When using  NET Core across platforms  the best development experience exists on Windows with the Visual Studio IDE which supports many productivity features including project management  debugging  source control  refactoring  rich editing including Intellisense  testing and much more  But rich development is also supported using Visual Studio Code on Mac  Linux and Windows including intellisense and debugging  Even third party editors like Sublime  Emacs  VI and more work well and can get editor intellisense using the open source Omnisharp project  2  Microservices When you are building a microservices oriented system composed of multiple independent  dynamically scalable  stateful or stateless microservices  the great advantage that you have here is that you can use different technologies frameworks languages at a microservice level  That allows you to use the best approach and technology per micro areas in your system  so if you want to build very performant and scalable microservices  you should use  NET Core  Eventually  if you need to use any  NET Framework library that is not compatible with  NET Core  there   s no issue  you can build that microservice with the  NET Framework and in the future you might be able to substitute it with the  NET Core  The infrastructure platform you could use are many  Ideally  for large and complex microservice systems  you should use Azure Service Fabric  But for stateless microservices you can also use other products like Azure App Service or Azure Functions  Note that as of June 2016  not every technology within Azure supports the  NET Core  but  NET Core support in Azure will be increasing dramatically now that  NET Core is RTM released  3  Best performant and scalable systems When your system needs the best possible performance and scalability so you get the best responsiveness no matter how many users you have  then is where  NET Core and ASP NET Core really shine  The more you can do with the same amount of infrastructure hardware  the richer the experience you   ll have for your end users     at a lower cost  The days of Moore   s law performance improvements for single CPUs does not apply anymore  yet you need to do more while your system is growing and need higher scalability and performance for everyday    s more demanding users which are growing exponentially in numbers  You need to get more efficient  optimize everywhere  and scale better across clusters of machines  VMs and CPU cores  ultimately  It is not just a matter of user   s satisfaction  it can also make a huge difference in cost TCO  This is why it is important to strive for performance and scalability  As mentioned  if you can isolate small pieces of your system as microservices or any other loosely-coupled approach  it   ll be better as you   ll be able to not just evolve each small piece microservice independently and have a better long-term agility and maintenance  but also you   ll be able to use any other technology at a microservice level if what you need to do is not compatible with  NET Core  And eventually you   d be able to refactor it and bring it to  NET Core when possible  4  Command line style development for Mac  Linux or Windows  This approach is optional when using  NET Core  You can also use the full Visual Studio IDE  of course  But if you are a developer that wants to develop with lightweight editors and heavy use of command line   NET Core is designed for CLI  It provides simple command line tools available on all supported platforms  enabling developers to build and test applications with a minimal installation on developer  lab or production machines  Editors like Visual Studio Code use the same command line tools for their development experiences  And IDE   s like Visual Studio use the same CLI tools but hide them behind a rich IDE experience  Developers can now choose the level they want to interact with the tool chain from CLI to editor to IDE  5  Need side by side of  NET versions per application level  If you want to be able to install applications with dependencies on different versions of frameworks in  NET  you need to use  NET Core which provides 100  side-by side as explained previously in this document  6  Windows 10 UWP  NET apps   In addition  you may also want to read   When should I NOT use  NET Core  When should I still use  NET Framework 4 x  instead of  NET Core  When should I use Xamarin  instead of  NET Core
