I have a user control that inherits from a base user control class. I can
view and edit the base user control in the designer. However, my child user
control fails to load in the web form designer. The error looks like this:

The file failed to load in the Web Form designer. Please correct the
following error, then load it again: An exception occured while trying to
create an instance of baseUserControl. The exception was "Unable to cast
object of type myServicedComponentClass to type myServicedComponentClass. "
..

I get no build errors, and my webforms with all their user controls function
properly when browsed.

Nevermind, i fixed it. In my 'baseUserControl' i moved the
'myServicedComponentClass' from being a class member to within a function.
VS.Net can now modify all the child classes in the designer.
