Will Roslyn be part of the .NET framework?

Question

Will Roslyn be part of the .NET framework? Which version and when?

It is actually available at GitHub but it is fairly big and I'm not able to load it in Visual Studio 2013 on Windows 7 without errors.

Answer 1

No, Roslyn is not included in the .Net Framework. Note that, even in .Net Framework 4.6 you'll still find the legacy csc.exe and vbc.exe compilers which we ship for compatibility reasons. They don't support the latest language features and, at release, you'll see that we've changed their banner text to make it clear that these are not the latest versions.

To get the Roslyn-based C# and VB command-line compilers, you have two options:

1. Install Visual Studio 2015 RC. or
2. Install the MSBuild_tools installer package.

You'll find the Roslyn-based command-line compilers at %ProgramFiles(x86)%\MSBuild\14.0\bin
