VS 2010 Trivial WCF Question

I'm just getting started with WCF. I created the service and added it to a project. I was able to see my new function but
not my new data contract when I consume the service.

I'm probably missing something simple, but here's my code. On the client end, CompositeType shows up ( the sample ), but
not my object ( TwoInts ).


<DataContract()>
Public Class CompositeType

<DataMember()>
Public Property BoolValue() As Boolean
<DataMember()>
Public Property StringValue() As String

End Class

<DataContract()>
Public Class TwoInts

<DataMember()>
Public Property MyInt1() As Integer

<DataMember()>
Public Property MyInt2() As Integer

End Class
