Any plan for using dotnet 5.0 ISourceGenerator for C# target?
See original GitHub issuehttps://devblogs.microsoft.com/dotnet/using-c-source-generators-to-create-an-external-dsl/
As of dotnet 5 there is an official support for source generator system ISourceGenerator which I think would be cleaner method to generate lexer and parser for antlr, include referencing antlr itself into any project
Is it possible and would you like to have official support for it?

Currently it’s only documented in the release notes where it was introduced (the link in comment https://github.com/antlr/antlr4/issues/3068#issuecomment-774859825 above). The readme should probably be updated to highlight it as the intended replacement for the Java toolchain when generating code for the optimized C# target.
The IKVM toolchain that led to that performance note was replaced in v4.6.5-beta001 by the new C# toolchain that is as fast as the Java toolchain, if not faster. The only reason it’s not enabled by default is I need to do a bunch of binary diffs of the output comparing the Java and C# tool to make sure they always produce exactly the same code.
