You need to run VS 2008 as administrator in order to debug UCMA 2.0 applications. 

If you don’t, you’ll get a fairly misleading TlsFailureException with he message “The operation failed due to issues with Tls. See the exception for more information." when you try and create your CollaborationPlatform.

UCMA2.0TlsFailureException

Hope that helps you get your first app up and running.

Thanks,
