Error CS0518 - Predefined type 'System.<Boolean|String|Object|..etc>' is not defined or imported

I get the above message when I hit recompile after editing a class.

I did some research and it seems it would have to do with the misconfiguration of the runtime assembly reference. I tried adding the relevant mscorlib from all the .NET installations I could find on my machine but I couldn't get the errors to disappear.

Is there somewhere that I could edit the compilation command line and arguments?

This issue is not directly related to the decompiler engine, if you have a concrete example were ILSpy generates wrong code or a wrong project file, please open a new issue.
