Visual Studio 2010 IntelliTrace: Why I'm getting the file not find exception in the Asp.Net MVC

Question

Why I'm getting these "file not found exception" errors in the IntelliTrace? The footer.ascx control is located in the "Shared" folder.

Does this mean each of my Html.RenderPartial() will throw 6 exceptions?

Answer 1

These exceptions are thrown only in debug mode. In release mode, view lookups are cached. So if the view "Footer" is found at ~/Views/Shared/Footer.ascx, the runtime will remember this and not look at the other possible locations for it, so these exceptions won't be thrown.
