title: How do you regenerate aspx.designer.cs in VS 2013
body: <p>I am having an issue with my aspx.designer.cs file not auto updating. I am using VS 2013.
  - I've tried to delete the designer file and rebuild. NO JOY.
  - There is no option to convert to web project. (it's vs 2013 and the project is already a web project.
  - searched Microsoft blogs for a solution and Microsoft doesn't even have a solution i can find.</p>
  
  <p>If anyone has a verified way to force this file to update or regenerate, please let me know. Having to manually add my controls to this file is just PAINFUL!!!</p>
