title: Designer.cs not updating when new controls added to .aspx
body: <p>I've added a new control to my aspx files and noticed that not only was the new control not added to the designer file but that it was also missing quite a few other controls that were added by other members of the team. I've tried deleting the designer.cs file and using "Convert to Web Application" with no success. Some other things i've tried have been excluding the aspx from the project, building, and then re-including with no success. I've also manually entered in a control that was missing in the designer into the designer. When I run after do so an error appears saying the control isn't defined, even though it actually is, and that I should check if I'm missing a directive. </p>
  
  <p>The first control I added was copy and paste from a similar control and made necessary changes. But, i've also tried manually creating the control with the same results.</p>
  
  <p>Any ideas?</p>
