Answer 1

In my case, I was trying to hit a WebAPI service on localhost from inside an MVC app that used a lot of Angular code. My WebAPI service worked fine with Fiddler via http://localhost/myservice. Once I took a moment to configure the MVC app to use IIS instead of IIS Express (a part of Visual Studio), it worked fine, without adding any CORS-related configuration to either area.
