What does the Visual Studio "Any CPU" target mean?
I've noticed that when compiling C# code in Visual Studio, there are typically options for compiling for 32/64 bit systems, and there's also one for compiling for Any CPU.
What's the difference between the two options? Does choosing Any CPU only compile down to an intermediate byte code while the first option compiles down to machine code (this sounds unlikely to me)? Or something else?
