This error is thrown by SF when I attempt to select a business object from the property sheet of an SF Textbox on a web page that inherits from "ApplicationBasePage". Since it is looking for the code in my project, if someone could tell me how the "MicroFour StrataFrame Extensibility" is searching maybe I could help track down the problem.

Any help will be appreciated.  Thanks Terry C

Exception
  The ApplicationBasePage could not be located.  Please rebuild project.

Yep, they will be in those locations as well. But they should be the same version as the .DLLs in your GAC.
