You are working with a Windows Communication Foundation (WCF) client application that has a generated proxy named SampleServiceProxy.

When the client application is executing, in line 02 of the following code, the channel faults (Line numbers are included for reference only.)

01 SampleServiceProxy proxy new SampleServiceProxy()
02try
03{
04proxy Processlnvoice(invoice);
05.
06catch
07{
08 (proxy. State == CommunicationState. Faulted)
09{
10
11.
12.
13 proxy Update Customer(customer);

You need to retumn proxy to a state in which it can successfully execute the call in line 13.

Which code segment should you use at line 10?

  • A

    proxy.CloseO;

  • B

    proxy new SampleServiceProxy0;c

    proxy.AbortO,

  • D
