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.

Language Design Discussion

We are now taking language feature discussion in other repositories:

Discussion about the transition of language design to the new repos is at https://github.com/dotnet/roslyn/issues/18002.

Download C# and Visual Basic

Want to start developing in C# and Visual Basic? Download Visual Studio 2017, which has the latest features built-in. There are also prebuilt Azure VM images available with Visual Studio 2017 already installed.

To install the latest release without Visual Studio, run one of the following nuget command lines:

nuget install Microsoft.Net.Compilers   # Install C# and VB compilers
nuget install Microsoft.CodeAnalysis    # Install Language APIs and Services

Daily NuGet builds of the project are also available in our MyGet feed:

https://dotnet.myget.org/F/roslyn/api/v3/index.json

See what's new with the C# and VB compilers.
