Edit Question
Title
Body
This is actually a two part question. First,does the HttpContext.Current correspond to the current System.UI.Page object? And the second question, which is probably related to the first, is why can't I use the following to see if the current page implements an interface: private IWebBase FindWebBase() { if (HttpContext.Current as IWebBase != null) { return (IWebBase)HttpContext.Current.; } throw new NotImplementedException("Crawling for IWebBase not implemented yet"); } The general context is that some controls need to know whether they are executing as a SharePoint webpart, or as part of an Asp.Net framework. I have solved the problem by requiring the control to pass a reference to itself, and checking the Page property of the control, but I'm still curious why the above does not work. The compiler error is: Cannot convert System.Web.HttpContext to ...IWebBase via a reference conversion, boxing conversion, unboxing conversion, wrapping conversion or null type conversion.
