Thanks for explanation. The problem is that even though the project
doesn't contain any extension methods (just calls them), it still
needs System.Core.dll. I've tried your workaround but it didn't help.
The compiler doesn't find the methods. Any further ideas?

My ultimate goal is for my project using extension methods to be
runnable under .NET 2.0, if that's even possible.
