Roslyn
Open-source implementation of C# and Visual Basic compilers with rich APIs for code analysis tools.
What is Roslyn?
Roslyn is the open-source .NET Compiler Platform that implements the C# and Visual Basic programming languages. It provides not only traditional compilation but also a rich set of APIs that allow developers to analyze, understand, and manipulate source code programmatically. This transforms the compiler from a command-line tool into a platform for building advanced development tools.
.NET developers, tool builders, and IDE extension authors who need to perform deep code analysis, create custom refactorings, or build integrated development experiences. It is essential for anyone developing advanced tooling for the C# or Visual Basic ecosystems.
Developers choose Roslyn because it offers unprecedented access to the compiler's internal data structures and logic through a public API. This enables the creation of powerful, context-aware code analysis tools and IDE features that were previously difficult or impossible to build, all while being the official, production-grade compiler for .NET languages.
Overview
The Roslyn .NET compiler provides C# and Visual Basic languages with rich code analysis APIs.
