Fix for empty widgets dialog when adding designer to exising widget with Sitefinity Thunder

"There are two ways to write error-free programs; only the third one works" (Alan J. Perlis)

Sitefinity Thunder enables fast and smooth creation of widget designers for existing widgets. You can take advantage of the Visual Studio plugin to speed up the development of your custom widgets.

NOTE: Valid for ASP.NET Web Forms web applications only!
