Popular Answer
This notification means that the thread is currently executing code, and therefore cannot be used to evaluate the expression.
Use
HttpContext.Current.ApplicationInstance.CompleteRequest
Instead of Response.End();
Response.Flush and Response.End does the same thing except Response.End stops execution of the page, and raises the EndRequest event.
Calls to the End methods throw a ThreadAbortException exception when the current response ends prematurely.
