Writing Code with Code: Getting Started with the Roslyn APIs

on YouTube ↗01h 01m

" summary

Shows how the Roslyn APIs are used to generate a full .NET client from a JSON schema: parse a TypeScript spec with TS‑morph into a normalized JSON schema, then build C# syntax trees with SyntaxFactory, call normalize whitespace and emit thousands of .cs files in seconds. Covers handling unions/polymorphism, query-string parameter classes, constructor selection, and serialization attributes, and reports a working generator covering ~80% of endpoints for an API that has ~420 endpoints and 4,000 data structures.
