Very much appreciate this video, thanks

One thing that wasn't necessarily covered explicitly was Design Time metaprogramming (rather then compile time, which is what source generators do).

The traditional way to do design time metaprogramming is to construct the text programmatically with either a string builder or T4 templates, but the more modern approach is to use the Roslyn Syntax API alongside Roslyn's Workspace API to modify project code directly. This is particularly useful when you are building a library from a predefined specification. As an example, I use it in my own game engine to generate Vulkan bindings directly from the Vulkan API Registry.

7:18 An important restriction: AFAIK Roslyn cannot run in a single-threaded environment; expression trees can.

Snippets. You can build snippets together with a string builder api to put together entire classes. The snippets can have replacement hooks such as specific strings. Its so much easier to read and write and its mostly compile time checkable.

Please tell me that's not your butt on the wall in the background.
