Hi,

I dont have any issue using the EasyDaClient with a Winform.

When I use the EasyDaClient within a WCF service I get this error:

The type initializer for 'OpcLabs.EasyOpc.DataAccess.EasyDAClient' threw an exception.

Here's my code:

Imports System.ServiceModel
Imports System.ServiceModel.Activation
Imports System.ServiceModel.Web
Imports OpcLabs.EasyOpc.DataAccess


<ServiceContract(Namespace:="")>
<AspNetCompatibilityRequirements(RequirementsMode:=AspNetCompatibilityRequirementsMode.Allowed)>
Public Class WCFQuickOPCAjax


<OperationContract()>
Public Function Test() As String
Try
Dim Client As New EasyDAClient

Return "test"
Catch ex As Exception
Return ex.Message.ToString
End Try

End Function
End Class

I someone could help me I would be happy as a clam in high water!

Many thanks,

Mathieu
