Alternative Managed API:

Have a look at System.Activator.CreateInstance and its various overloads. Sample:

Guid CLSID_ShellDesktop = new Guid("00021400-0000-0000-C000-000000000046");
Type shellDesktopType = Type.GetTypeFromCLSID(CLSID_ShellDesktop, true);
object shellDesktop = Activator.CreateInstance(shellDesktopType);

If you just want to create an instance on a specific server, you can pass the server name into GetTypeFromCLSID:

Guid CLSID_ShellDesktop = new Guid("00021400-0000-0000-C000-000000000046");
Type shellDesktopType = Type.GetTypeFromCLSID(CLSID_ShellDesktop, "REMOTESERVER", true);
object shellDesktop = Activator.CreateInstance(shellDesktopType);
