Ah Source Generators, after all these years still badly documented, when searching you most likely will find the original implemenation meanwhile deprecated, have poor tooling with string concatenation, and only have a few great blog posts from .NET MVPs to rely on.
:shrug: we're using them very effectively and there are plenty of resources at this point.
Very useful for reducing boilerplate and we can do some interesting things with it. One use case: we generate strongly typed "LLM command" classes from prompt strings.
There are plenty of resources, outside Microsoft Learn that is, and the content is mostly understandable by those of us that have either watched conference talks, or podcasts on the matter.
Now having someone diving today into incremental code generators, with the best practices not to slow down Visual Studio during editing, that is a different matter.
They are naturally useful, as a user, as a provider, Microsoft could certainly improve the experience.
