title: Drag and drop the user control won't work in .net windows project
body: <p>I created a user control and it shows up on the tool box as form components. Then when I try to drag and drop the user control on to a form , I get this visual studio error.</p>
  
  <p>" The specified named connection is either not found in the configuration ,not intended to be used with the entity client provider or not valid."</p>
  
  <p>Why am I getting this error? </p>
  
  <p>But some other user controls I can drag and drop which are under the same project. I don't know what I missed in creating this user control.</p>
