When to use CodeRush Classic or CodeRush for Roslyn?

Microsoft’s has started new way of development in Open Source world with the  paradigm “Compiler as a service”. Now Microsoft has lots of open source projects including the .NET Compiler Platform (“Roslyn”).NET Compiler Platform (“Roslyn”). The .NET Compiler Platform ("Roslyn") provides open-source C# and Visual Basic compilers with rich code analysis APIs. You can build code analysis tools with the same APIs that Microsoft is using to implement Visual Studio!. According to these dramatic changes in the development on the Microsoft platform lots of tools are adopting ways to move along these. After a while again I got chance to install CodeRush in Visual Studio IDE and I there are two different flavours of CodeRush. This makes me little confuse that which one should i install to work with.

After checking through documentation and ready some blog posts related to my question I got that When to use this newer version of CodeRush for Roslyn or CodeRush Classic. Actually CodeRush Classic work with the prior version of .NET Framework 4.6. With this newer version of .NET framework which is shipped with the Microsoft’s open source projects which based on the Rosyln compiler platform. Below are points which help you to decide that which version suits to your development environment:

  1. If you are using Visual Studio  2015 and .NET framework 4.6 (above) then CodeRush classic does work for you. In this case you should install CodeRush for Roslyn. This does not has all the feature of the CodeRush Classic but newer version will defiantly improve this open source stack.
  2. If you are working with older version of .NET Framework then you’ll need CodeRush Classic. If you need both, you can install both versions simultaneously and defiantly i try this too.
  3. CodeRush Classic supports C# 5.0, VB10, ASP.NET, HTML, JavaScript, XML, and XAML. In this case, for the newer version of language CodeRush for Roslyn is the only option and may be in near future Classic version of CodeRush go obsolete.
