Save Changes() Return Redirect To Action("Index") Catch Return View() End Try End Function ' ' GET: /Contact/Delete/5 Function Delete(By Val id As Integer) As Action Result Dim contact To Delete = (from c in _entities. Our application will be more difficult to maintain and modify over time.The goal of this multiple iteration approach is to enable you to understand the reason for each change.In this second iteration of the Contact Manager application, we add basic form validation.But is there a way to build pages with richer content while also achieving fast response times?Here are some techniques for reducing the number of HTTP requests, while still supporting rich page designs.
