I have converted a large project, currently in VS 2012 from a Web Site project to a Web Application project.
I have added the namespace to all of my .cs files.
I have ran the "Convert to web application" on the project and it has generated all of the needed files. (So I do have the designer files created as part of this upgrade)
When I compile, it errors off on all of the references in my C# code behind file for all of the UI Controls. The error indicates that the control does not exist. The controls are there, and they are present in the designer files.
I have cleaned my solution and no matter what I do I get this error.
Any ideas / suggestions of things to try? Have I missed something in the conversion to a Web Application?
