Raise event doesnt fire in host service when called from client

Question

I have a problem with event that doesnt raise when its raised from client. Searshed for a solution for days now without any luck...

I dont know if its a WCF problem or a general VB.net problem. Maybe threading problem?

No error messages at all.

'My WCF service class   
Public Class LogProLiveCommunication    
   Implements ILogProLiveCommunication     
   Public Event Test(ByVal sender As System.Object, ByVal e As System.EventArgs)
   'This function is called by the WCF client and works ok except from the raise event Test!?!    
   Public Function ConnectToLogProLive(ByVal clientName As String, ByVal clientIP As String) As String Implements ILogProLiveCommunication.ConnectToLogProLive        
      MsgBox("Client Connected: " & clientName & " IP: " & clientIP)        
      Debug.Write("Service: RaiseEvent Klient Ansluten: " & clientName & " IP: " & clientIP) 'This works        
      RaiseEvent Test(Me, New EventArgs) 'This doesnt work        
      Return "Ok" 'Works    
   End Function    
   Public Sub raiseEventTest()        
      RaiseEvent Test(Me, New EventArgs) 'This one is fired ok    
   End Sub
End Class
