Roslyn-SDK templates and Syntax Visualizer
Roslyn is the compiler platform for .NET. It consists of the compiler itself and a powerful set of APIs to interact with the compiler. The Roslyn platform is hosted at github.com/dotnet/roslyn. The compiler is part of every .NET installation. The APIs to interact with the compiler are available via NuGet (see the Roslyn repository for details). The Roslyn SDK includes additional components to get you started with advanced topics such as distributing a Roslyn analyzer as Visual Studio extension or to inspect code with the Syntax Visualizer. The documentation for the Roslyn platform can be found at docs.microsoft.com/dotnet/csharp/roslyn-sdk. This repository contains code for both the Roslyn-SDK templates and Syntax Visualizer.
For older versions of Visual Studio the .NET Compiler Platform SDK is available as an extension in the Visual Studio gallery.
