使用Visual Studio 2015调试WPF应用程序时出现XamlParseException

I'm working on a WPF application I used to debug with VS 2012. Since I switched to Visual Studio 2015, I don't manage to debug it any more.

I can even debug it in VS 2015 by attaching the process after it's been launched.I'm working on a WPF application I used to debu
