Why there is no release configuration on Windows for Listener plugin?

Hi All,

          I'm using Listener plugin from CS5 SDK. There is only Debug configuration on Windows example project. I created a Release configuration but i get linker errors if Code generation option is set to Multi Threaded and also if I set it to Multi Threaded Debug the project build succeeds.

          Is there any reason for not giving the Release configuration?

Thanks,
