I created an empty MVC 6 project and gradually added features (MVC, initialized my own bower.json file etc) to it to see how the new VS 2015 project tooling/structure works.
The first time the site loads I see an error in the IE tab "IIS 10 502.3 Bad Gateway" then the site continues to load the HomeController's Index view.
Any idea how I can try to track down a more detailed error message? IIS Express is the only option I see in VS 2015. I tried using Fiddler but there aren't any 502 errors shown. It seems to slow the site down initially.
I'd just like to know for future reference what might be causing this.
