I don't know any better alternative than ANTLR for grammar generation, this is unfortunately written in Java, so there is not a good way to avoid it. I mean, I could manually generate .cs files and commit them to the repo.

Antlr4BuildTasks at least automates this step (both downloading java and building antlr4).

Long story short, I don't see a better alternative for grammar generation now.

Ok, I thought I'd raise the subjective "issue". There is a port of Antlr to .net, but I don't know whether it is well maintained or how compatible it is.
