C# Source Generators

A curated list of C# Source Generators and related resources for compile-time code generation.

Code Converter

Convert code between C# and VB.NET using Roslyn, available as a Visual Studio extension, online tool, CLI, and library.

CodeAnalysis.CSharp.PatternMatching

A pattern matching library for Roslyn syntax trees that simplifies code analysis and refactoring tasks.

CodeGeneration.Roslyn

A deprecated .NET tool for performing Roslyn-based code generation during build with design-time IntelliSense support.

Dotnet Script

Run and debug C# scripts from the .NET CLI with inline NuGet references and full IDE support.

FlubuCore

A cross-platform build and deployment automation system using C# scripts with a fluent interface and full .NET ecosystem access.

MirrorSharp

A reusable client-server code editor component built on Roslyn and CodeMirror for .NET languages.

roslyn-linq-rewrite

A Roslyn-based compiler that rewrites LINQ expressions into procedural code to minimize allocations and dynamic dispatch in C#.

RoslynQuoter

Refactoring Essentials for Visual Studio

A Visual Studio extension and NuGet package providing C#/VB refactorings, analyzers, and code converters.

Roslyn Clr Heap Allocation Analyzer

A Roslyn-based C# analyzer that detects explicit and implicit heap allocations like boxing, closures, and delegate creations.

Roslynator

A comprehensive set of code analysis tools, refactorings, and client libraries for C# development, built on the Roslyn compiler platform.

SonarC#

Static code analyzer for C# and VB.NET that detects bugs, vulnerabilities, and code smells to improve code quality and security.

StyleCopAnalyzers

An implementation of StyleCop's code style and consistency rules as Roslyn analyzers for .NET projects.
