WcfStorm is a dead-simple, easy-to-use test workbench for WCF Services. It supports all bindings (except webHttp) including netTcpBinding, wsHttpBinding and namedPipesBinding to name a few. It also lets you create and functional and performance test cases thus ensuring that your WCF Services are bug-free and functioning exactly as you've designed.

Have you already decided to host your own WCF Services instead of hosting in IIS? Do you have several services and find it a challenge to manage it all? Would you like have them all in one place? Would you like to enable tracing and not worry about the size of the trace log?
