No, it doesn't compile at the moment. There are a few things that are missing. Examples:
- InvariantCultureIgnoreCase, which could possibly be replaced with OrdinalIgnoreCase
- Reflection methods regarding custom attributes
char.GetUnicodeCategory missing, but apparently planned for .NET Standard 2.0
- ... maybe more issues
I didn't try to find all the issues. I will try to create a PR once .NEt Standard 2.0 preview is released and if Irony is migrated to GitHub (since Codeplex is shutting down soon anyway).
I guess that I'm actually asking is whether this project is still maintained and welcomes PRs.
