It is not interoperable with WSE 3.0 and WCF. * WSE 3.0 was released in October 2005 and has design time support with Visual Studio 2005. It includes policy framework enhancements including security based on policy assertions (associating CLR client proxies with policy files), turnkey security scenarios for securing end to end messages, extensibility mechanisms for user-defined policies in code and a simplified policy model applied to a message exchange instead of on a per-message level. It supports updated
