C# Code Generators: Writing Code That Writes Code

on YouTube ↗42m

" summary

The talk explains C# source generators introduced with C# 9 and .NET 5 (Roslyn), contrasting them with older tools like PostSharp, Fody, and CodeSmith. It covers how generators run at compile time with access to compiler internal data structures, shows examples of writing C# generators, and discusses scenarios and benefits (e.g., replacing slow reflection) so listeners can build their own generators.
