I build my custom dll using g++ and Cygwin environment.
Whe I try to call it, from C# application, it immediatly freeze.

How can I do..?
Fad.

C# code:
[DllImport("faddll.dll", CharSet = CharSet.Auto, EntryPoint = "Somma")]
public static extern int MySum(int a, int b);
int x = MySum(1,2);

C++ code:
#include <stdio.h>
#include <windows.h>

#define DllExport extern "C" __declspec(dllexport)

DllExport int MySum(int a,int b);

int MySum(int a, int b)
{
   HMODULE h = LoadLibrary("cygwin1.dll");
   void (*init)() = (void(*)()) GetProcAddress(h,"cygwin_dll_init");
   init();

   return a+b;
}
