Well, the error is quite clear about the error. It looks like you have a class that is called “AIBservice” which has an “DesignerCategory” attribute. That attribute seems to be not supported.

I don’t have a windows phone and never developed for one so i’m just guessing here. That attribute is usually used by the form designer of Visual Studio. Do you have created or imported any Form components in your project? What is that AIBservice ?
