Nick is write that you should include the extern keyword in the P/Invoked method declaration:
[DllImport("MyDll.dll")]
public static extern int sum(int x, int y);
Also make sure that MyDll.dll is in a directory in the PATH environment variable or the application directory so that it can be found. Examples of such directories are C:\Windows, C:\Windows\System32, etc.

I just wanted to add that you can use depends.exe to make sure your functions are exported as you think they should be. Depends is a great Platform SDK tool and, if you choose the default options when installing VS.NET, should be installed. Just run the "Visual Studio .NET Command Prompt" in your VS.NET programs group off the start menu, cd' to the directory with your native DLL, and type "depends.exe MyDll.dll". If you've added the Platform SDK's bin directory to your system or user PATH environment variable (I like to manage all my PATH, INCLUDE, and LIB directories like this), you can just type "depends" in your Start->Run prompt and load your DLL. That will show you your exports.
