The sequel to the previous MSDN article. A detailed introduction into code fixes.

Older but still not outdated, very detailed MSDN article on writing code analyzers.

Comprehensive list of additional learning sources, samples, and experimental and productive source generators. A perfect reference once you grasp the basics.

The mother of all Roslyn tutorials :-) A realistic step-by-step introduction to syntax and semantic analysis as well as the syntax transformation.

Original announcement of the C# 9.0 Source Generators feature. Explains what source generators are, in which scenarios they are useful, and shows how to write a simple source generator.

Series of blog posts that explore the Roslyn compiler API. It introduces the power of Roslyn through small self-contained examples. A perfect tutorial to start with :-)

Analyzer library for C# and VB.NET. Offers diagnostics in many categories like performance, coding styles, as well as some basic refactorings.

Reports diagnostics for C# coding guidelines (

Set of analyzers and code fixes focusing on the correctness and performance of C# programs. Inspired with Google's

Code fix that generates arbitrary complex object-object mappings. It recognizes out of the box a large number of scenarios where mappings are used. A design-time alternative to

GitHub organization for the development of Roslyn analyzers. Various repositories within the organization cover analyzers for ASP.NET Core, WPF, IDisposable, usages of System.Reflection, etc.

Diagnostic analyzers developed by the Roslyn team. Initially developed to help flesh out the design and implementation of the static analysis APIs. The analyzers cover code quality, .NET Core, desktop .NET Framework, comments in code, and more.

Proof-of-concept of a dependency injection container that transfers huge piece of resolving logic to the compilation stage. Offers additional compile-time safety and fast runtime resolution.

Automatically implements equality and hashing for classes and records. Supports different comparison strategies. Offers similar functionality like IL weaving-based

Reflection-free JSON serializer. Allows extremely fast JSON processing by generating reflection-free serializers at the compile time.

Online application that lets you experiment with source generators. Perfect for learning and testing your ideas. Write your own source generator or learn from built-in examples and see the generated output.

Compile-time dependency injection container. Compile-time checked, reflection-free and runtime code generation free, thus fast and

Low-level, lightweight and performance-focused serializer for C# struct types. Auto-generates C# serialization code to achieve peak runtime performance and efficiency.

Roslyn's journey, presented by Mads Torgersen, the lead designer of C#. Inspiring story on how Roslyn project started and why, and what it took to make it open source.

In-depth look at Roslyn's performance with the focus on memory consumption.

Inspiring introduction on how Roslyn team implemented immutable, reusable trees with cheap parent references and many other goodies. Quote: "But on the Roslyn team we routinely do impossible things" :-)

Excellent explanation why ReSharper will not use Roslyn. Includes good discussion on static code analysis and some limits of Roslyn.

Insight on how Roslyn team approaches the topic of evaluating and achieving performance.

Library for testing analyzers and code fixes with NUnit, xUnit and MSTest frameworks. A part of
