I can't find any documentation that shows how to get ANTLR support in Visual Studio 2022. It seems like the ANTLR extension developers haven't kept up with the changes made to the Visual Studio API object model: ANTLR VSIX is only compatible with Visual Studio 2019, and ANTLR Language Support won't work with anything newer than Visual Studio 2017.
How can I work with ANTLR grammars and build parsers in .NET 6.0 with Visual Studio 2022?
