The .NET Compiler Platform ("Roslyn") provides open-source C# and Visual Basic compilers with rich code analysis APIs. It enables building code analysis tools with the same APIs that are used by Visual Studio.

Try new language and IDE features

Just want to provide feedback on new language features and IDE features?

  • Try out Visual Studio 2015 Preview, which has the latest features built-in.

    Want to keep your box clean? You can use prebuilt Azure VM images with VS 2015 Preview already installed.

  • You can also try April's End User Preview, which installs on top of Visual Studio 2013. (Note: The VS 2013 preview is quite out of date, and is no longer being updated.)

Build tools that understand C# and Visual Basic

Get started building diagnostics, code fixes, refactorings, and other code-aware tools!

Click on the version of Visual Studio you are using for installation instructions.

Or, you can grab the latest NuGet Roslyn compiler package. From the NuGet package manager console:

Install-Package Microsoft.CodeAnalysis -Pre
