Workaround for C# conditional compilation depending on CLR version
I have C# code that needs compiling in both VS .NET 2003 and VS .NET 2005. Turns out the latter defaults to .NET 2.0, and a few tweaks are needed to my code when building in this environment.
I understand C++ supports this by conditional compilation via the predefined __CLR_VER macro, but C# does not. What is the best workaround without forking code and setting up two seperate projects?
