Ok, so you have developed a nice WCF Service with proper implementation of custom fault exception handling, now you want to call this service in a web application or other client application and catch the fault exception in your client code. For simplicity I am using a web page, the following code is self explanatory.

  1: Protected Sub btnGetCustomers_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles btnGetCustomers.Click

  2: 

  3:         Using wcfSrv As CustomerWcfService.CustomerServiceClient = New CustomerWcfService.CustomerServiceClient("WSHttpBinding_ICustomerService")

  4:             Try

  5:                 Dim custArr() As CustomerWcfService.Customer

  6:                 custArr = wcfSrv.GetCustomers()

  7:                 For Each cust As CustomerWcfService.Customer In custArr

  8:                     Response.Write("ID: " & cust.ID.ToString & " Name: " & cust.Name & "<br/>")

  9:                 Next

 10:                 lblStatus.Text = "No of Customer Records found: " & custArr.Length.ToString

 11: 

 12:                 'Custom Fault Exception Response from Service

 13:             Catch ex As ServiceModel.FaultException(Of CustomerWcfService.ErrorResponse)

 14:                 lblStatus.Text = "Code:" & ex.Detail.Code.ToString() & " Messgage:" & ex.Detail.Message & " Details:" & ex.Detail.Details

 15:                 wcfSrv.Abort()

 16: 

 17:                 'General Fault Exception

 18:             Catch ex As ServiceModel.FaultException

 19:                 lblStatus.Text = ex.ToString()

 20:                 wcfSrv.Abort() 

 21: 

 22:                 'General Exception

 23:             Catch exp As System.Exception

 24:                 lblStatus.Text = "Error:" & exp.ToString()

 25:                 wcfSrv.Abort()

 26: 

 27:             Finally

 28:                 wcfSrv.Close()

 29:             End Try

 30: 

 31:         End Using

 32: 

 33:     End Sub
