| Guest | WFC and Inherited List Hi Im trying out WCF for the first time and have hit a small snag. In my project I have a class called Passenger which simplified look like this <DataContract> _ Public Class Passenger <DebuggerBrowsable(DebuggerBrowsableState.Never)> _ Protected mAge As Integer = 0 <DataMember()> _ Public Property Age() As Integer <DebuggerStepThrough()> _ Get Return Me.mAge End Get <DebuggerStepThrough()> _ Set(ByVal value As Integer) Me.mAge = value End Set End Property End Class I then have a strong type collection of Passengers with an additional method <DataContract()> _ Public Class PassengerList Inherits List(Of Passenger) Public Function FooBar() As Boolean ' Some code that doesn't matter End Function End Class The PassengerList object is then exposed through my service contract. When I try to add a Service Reference in my client project I get an error. Now I assume this has to do that since the members of List(Of T) which I inherit do not have the DataMember attribute added to its members (like the items). How is this kind of stuff done in a "Correct WFC way" ? Thanks for your advice! //Andreas |

| Guest | Re: WFC and Inherited List Excellent! Once I turned on the debug information I realized I had forgotten to make my KnownType method static so the problem was related to the fact that it could not locate the specified method. Thanks!
