 Hello,

 I have a problem with WCF.

 If I have this service contract:

 ServiceContract()  _
 Public Interface IHelloService
 OperationContract()  _
 Function Greet(ByVal name As String) As IEnumerable(Of Objekt)
 End Interface

 This Service:
 Imports System.ServiceModel

 Module Module1
 Sub Main()
 Dim host As ServiceHost = New ServiceHost(GetType(HelloService))
 host.Open()
 End Sub
 End Module

 The implementaion of HelloService of the Service:
 Imports Contracts

 Public Class HelloService
 Implements IHelloService
 Public Function Greet(ByVal name As String) As IEnumerable(Of
 Objekt) Implements IHelloService.Greet
 Dim myObjekt As Objekt = New Objekt
 Dim myObjekt2 As Objekt = New Objekt

 myObjekt.text = Hallo
 myObjekt.number = 3 + name.Length

Dim list As IList(Of Objekt) = New List(Of Objekt)

 list.Add(myObjekt)
 list.Add(myObjekt2)

 Return list

 End Function

 End Class


 And this client:
 Imports System.ServiceModel
 Imports Contracts

 Module Module1

 Sub Main()
 Dim binding = New BasicHttpBinding()
 Dim address = New EndpointAddress(http://192.168.100.110:8080;)
 Dim client = New HelloClient(binding, address)
 Dim myObjekt = client.Greet(name)

 Console.ReadLine()
 End Sub
 End Module

 The implementation of HelloService from the client:

 Imports System.ServiceModel
 Imports System.ServiceModel.Channels
 Imports System.Runtime.Serialization
 Imports Contracts

 Public Class HelloClient
 Inherits ClientBase(Of IHelloService)
 Implements IHelloService
 Public Sub New(ByVal binding As Binding, ByVal address As EndpointAddress)
 MyBase.New(binding, address)
 End Sub

 Public Function Greet(ByVal name As String) As IEnumerable(Of
 Objekt) Implements IHelloService.Greet
 Return Channel.Greet(name)
 End Function
 End Class


 I execute the service and execute the client.
 I get this Exception:
 Exception Non-empty prefix must be mapped to non-empty namespace URI.
