You don't have to register anything, but you should make sure that you are
compiling the exported functions in the DLL as C functions, not C++. C++,
as you certainly must know, changes the exported names of functions so that
their parameter and return types are part of their name. This allows
overloading of functions, since you can distinguish between int A( float b )
and int A( long b ) by the mangled function name, but it also makes it
harder to call from systems where you have to know the actual exported name.
The depends.exe tool will show you the actual exported names from a DLL and
you should be able to use this tool to see if what you are telling your C#
code to call is actually what the DLL is exporting...
