    Im having a little trouble with the fiollowing in a web service

    Public Interface IBookAttribute
    Property Description() As String
    End Interface

    I get "Cannot serialize Inteface MyApp.IBookAttribute"

    Is it possible to do so, or are interfaces not a good idea for web services
    (why not?)?

  2. I think it's because you don't impliment ISerializable. The webservice
    doesn't know how to "translaste" your interface into XML. Do some research
    on ISerializable and webservices.

    I think that interfaces are almost by definition not serialisable. To
    be serialisable a class must provide a default constructor - one with
    no parameters: interfaces don't have and can't have constructors.

    Search MSDN for an article about how to use interfaces and web-services.
    Haven't got the link handy, but the articles is out there somewhere :)
