Debugging Device Control Libraries

hi, has anyone tried to debug a device control library in whidbey, I'm trying to run a control library wich i made for the full version of the framework, the control works all right there, then i took my control code, and pasted it in a device control project, after fixing all the dependencies, i try to run the control library, and i get the following error
Cannot complete the Operation
Unspecified Error,
i also tried it making a new control with just a button and i get the same error
has anyone else had this error?
has it been reported?
thanks!
