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.
Want to start developing in C# and Visual Basic? Download Visual Studio 2015, which has the latest features built-in. There are also prebuilt Azure VM images available with VS 2015 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
To get the latest "preview" drop, published about once per month, add the -pre switch to the nuget commands.
