VS2005 Web designer bug
I was refactoring my little heart out on a project when I realized I had a Hyperlink control in several places that always pointed to the same place. So I made a derived class in App_Code, added it to pages/controls in web.config (<add assembly="App_Code" namespace="Awesome.UI" tagPrefix="Awesome"/>), and replaced away.
Well wouldn't you know it, doing this breaks the design view of the page when it has a master. You get the dreaded "Error creating control - Content1" exception. Boo.
I haven't been able to Google anything out of this. Has anyone else had the problem?
