I'm writing a class library in C#/.NET.
I need to compile it for two different frameworks:
- 4.0 (using for debug myself)
- 3.5 (using on client).
I want to have one set source files for the two projects, so I can make corrections in 1 copy of files and they are included in the other project automatically.
Now, if I even use "add existing item", VS 2010 creates copies; and I need to copy the latest versions every time.
I can't just change a target in project, because I'm using different versions of .dll references, and because ms vs has some quirks.
