It is a well known issue with Resharper that it fails to recognize generated C# files using Custom Tasks (making intellisense fail). Does anyone know how to fix this without adding the files to the project?
As this issue is experienced and reported again and again for years, surely there must be someone who has cracked it by now?
I found an extension for Resharper: ReSharper.ExternalCode.
Tip for Antlr: add
obj\Debug in Resharper -> Code Inspection -> External Code and reload solution.
It's works for me.
