C# Source Generators

A list of C# Source Generators (not necessarily awesome), because I haven't found a good list yet.

C# Source Generators is a Roslyn compiler feature introduced in C#9/.NET 5. It lets C# developers inspect user code and generate new C# source files that can be added to a compilation.

to your generator repo - let's get it started!

Documentation and samples

Source Generators

  • AutoDeconstructable - stars last commit Generator for efficient and automatic flat text serializer/deserializer using Deconstructable aspect in NTP library.

  • Avalonia.NameGenerator - stars last commit Generates typed references to named Avalonia XAML controls.
  • avatar - stars last commit A modern compile-time generated interception/proxy library.
  • Azura - stars last commit Generates binary [de]serializers on Streams at design time.
  • boilerplatezero - stars last commit WPF Dependency Property Generator.
  • Cloneable - stars last commit auto-generate Clone method.
  • Data Builder Generator - stars last commit Generate data builder patterns for your model classes.
  • Generator.Equals - stars last commit generates equality and hashing for classes and records, supports a number of strategies for comparing collections and properties.
  • IoTHubClientGenerator - stars last commit Build a C# Azure IoT Device client program in seconds!
  • JsonByExampleGenerator - stars last commit - generate classes based on example json files in your project.
  • JsonSrcGen - stars last commit - compile time JSON serializer generation.
  • lambdajection - stars last commit Framework for building AWS Lambdas using dependency injection and aspect-oriented programming.
  • MapTo - stars last commit - A convention based object to object mapper similar to Automapper.
  • MemberAccessGenerator - stars last commit generates
    methods that return property value for a given property name or index (e.g. in positional records).
  • MiniRazor - stars last commit Portable Razor compiler & code generator.
  • MockableStaticGenerator - stars last commit A C# source generator to make an interface and a class wrapper to test static/extension methods.
  • MockSourceGenerator - stars last commit A C# mocking library that generates mocks at compile-time using a source generator.
  • netautomaticinterface - stars last commit .Net Core Source Generator for Automatic Interfaces.
  • PrimaryConstructor - stars last commit Generate primary constructor from readonly fields.
  • PrintMembersGenerator - stars last commit helps re-defining C# record's PrintMembers method to force include/exclude certain members.
  • SmallSharp - stars last commit Create, edit and run multiple C# 9.0 top-level programs in the same project by just selecting the startup program from the start button.
  • StackXML - stars last commit Stack based zero-allocation XML serializer and deserializer.
  • StringLiteralGenerator - stars last commit for optimizing UTF-8 binaries.
  • StrongInject - stars last commit - compile time dependency injection for .NET.
  • StructPacker - stars last commit binary serializer that auto-generates C# serialization code to achieve peak runtime performance and efficiency.

I made a thing:

If you're building Roslyn Source Generators or Analyzers check it out, it makes debugging them inside the compiler easier. #roslyn #csharp #dotnetcore #sourcegenerators #analyzers



Demo, PoC and excercise projects

Maybe they can inspire you too!

  • AutoCoder - stars last commit for effective and flexible object coding.
  • RyanAlameddine/SourceGeneratorDemo - stars last commit contains 3 demos: hello world, INPC and OpCode class.
  • TMC-CSharp/CodeExerciseLibrary - stars last commit Library to help creating C# exercises. Generates missing methods and classes inside tests on the fly by using Source Generators.
  • DpdtInject - stars last commit DI container based on C# Source Generators. Its goal is to remove everything possible from runtime and make resolving process as faster as we can. This is achieved by transferring huge piece of resolving logic to the compilation stage into the source generator.
  • jakubsturc/talk-csharp-source-generators - stars last commit contains 4 generators: AutoNotify, ConsoleWritelineHijack, HelloWorld and SettingsXml, plus nice presentation slides.
  • Compile Time Method Execution Generator - stars last commit proof of concept that allows executing a method during compilation, so that it can be really fast during runtime.

Projects using custom Source Generators "internally"

  • NetFabric.Hyperlinq - stars last commit generates overloads for its extension methods.
  • RestEase - stars last commit uses Source Generator to generate interface implementations on compile time instead of in runtime via Reflection.Emit.
  • WarHub/wham - stars last commit generates code for immutable tree object graph based on red-green node approach used in Roslyn; generates custom XmlSerializer that supports C#9 records and ImmutableArray.
