We somewhat work around this today in Type Providers with a series of caches that were added in the VS 2019 16.0/16.1 timeframe. The upside is correctness, but the downside is a huge hit to design-time performance. This is effectively what Type Provider do today since they're asked to provide "fresh" types whenever the language service needs to re-typecheck things. For example, you want generated source to be up to date, so the safest thing to do is regenerate on every keystroke. There's some interesting challenges to solve that are not unlike what Type Providers struggle with today. There's extensive design-time support planned, which you can read the beginnings of here.

I or my company would be willing to help implement and/or test the Source Generators feature is currently in a very early preview.

This is not a breaking change to the F# language design.

The disadvantages are the repetition of a feature and the compiler performance penalty of executing the type checker twice when this feature is used. It's basically all the benefits of type providers without the complexity. The advantages of making this adjustment to F# are an easy form of meta programming. TypeProviders which take specialized knowledge to author.The existing ways of approaching this problem in F# are: Pass 2 Combine all code, type check, emit.

Send that information to Source Generators that output new code files or syntax trees.Pass 1 Parse and type check the project code (the type check may be optional as it will contain errors).The idea is to execute the compiler in two passes: Add support similar to C# Source Generators
