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.

Source     : MicroFour StrataFrame Extensibility

Stack Trace:
   at MicroFour.StrataFrame.Extensibility.BusinessObjectNameTypeEditor.EditValue(ITypeDescriptorContext context, IServiceProvider provider, Object value)

I also get the same error from within the SF sample web application.

There is only one set of assemblies referenced in the GAC.

If the type editor is looking for the business objects initialized in the ApplicationBasePage in the App-Code folder of my web application, how is it trying to find the reference? Is there something in my app that should also be in the GAC?

Extensibility...that is what is attempting to look in the GAC.  I have just tested this over and over again...so there is definitely something not lined up right on your machine.  Here is what I would do:

1. Make sure that you have only a single version of Microfour assemblies in the GAC
2. Go to the c:\program files\common files\microfour\strataframe and make sure that you have the most recent version of the SF assemblies (if you are running the 1.6.6 beta they will be 1.6.5.3 for the file version).
3. You can also verify the versin from within VS by clicking StrataFrame -> Version
4. Next, remove all MicroFour assemblies from the GAC
5. Replace the removed assemblied from the GAC with the ones located in the c:\program files\microfour\common files\microfour\strataframe

It really shoudn't be more complicated than that...that is why this is quite strange.
