Hi,

You could try:

class DaemonPlugin
{
  [DllExport("add",CallingConvention = CallingConvention.Cdecl)]
  public static int add(int left, int right)
  {
     return left + right;
  }
}

Then write a C++ wrapper around the exported classes.  I don't think C#
will be able to handle the pointers from the MySQL plugin API (or to do so
would be tremendously cumbersome) so a wrapper around the .NET exported
.NET code which handles the C memory management, etc, needed for a plugin
will work best.

I don't know much about this.  I learned the above from a few google
searches, but hopefully it will get you going in the right direction.

Regards,

--Justin
