尝试在Visual Studio 2015上运行WCF测试客户端时出错

Question

I have a C# Web Application that work as a Gateway, with some wcf services created on it. If i set any of the .svc files as the Start Page and try to run it, the WCF Test Client load, the green bar loads to half, and then the App crashes without even reaching the source code.

The weirdest thing, if i switch to Visual Studio 2013, the app and the WCF Test Client runs normally. The VS 2013 is the Professional version, and the 2015 is Community.

Below the generic error it generates:
