Create .dll with Studio.NET in C++

I am trying to export some functions that I can import from other c++ or c# code. I know this can be done without creating a .dll project. I use the __declspec(dllexport) command on the function prototype and
for the project properties I have configuration type set to dll.
This code builds but there is no .dll file being generated. Any ideas why? Thanks for any help.

------------------------------------

Code:

---

#include <iostream>
#include <windows.h>

using namespace std;

__declspec( dllexport ) int AddNums(int a, int b); // prototype


int AddNums (int a, int b)
{
  return a+b;
}

---

Make sure under General in your project properties Configuration Type is Dynamic Library. Also check to see that the output (Linker->General) has .dll for its extension (eg, "$(OutDir)\$(ProjectName).dll")

Great, thats it. Thanks a lot.
