.NET Version

[Guest]

If I compile a C# class library using VS 2003. Then build an application in
VS 2005 and reference that library. When I execute the application will the
source in the DLL be executed by .NET 1.1 or .NET 2.0 framework.

You can only have one framework version per process (exe); in this
case, the 1.1 assembly will run in the 2.0 runtime, which is fine as
all the 1.1 IL is supported. You can't, however, use a 2.0 assembly
from a 1.1 process.

Just as info:

It's true that currently only one framework version per process can run.
Though with Silverlight 1.1 and future CLR's it will (should) be
possible to use different framework versions parallel in one process.
