Where can I find a working library for making a LLVM compiler?

I found this library (https://github.com/dotnet/LLVMSharp) that provides extern references for the LLVM lib, but it doesn't work and seems to be abandoned. Does anyone know of other C# libraries that would help with making an LLVM compiler? Even better if it natively supports Antlr ASTs. Thanks

what about it doesn't work? @Tanner Gooding might be able to help with that
