Can I use Proxy.Open()
as an indication to whether the connection should work or not?
I would like to check if a connection is available first, and then, if its not, i won't make any calls to the service during the run of the application.
Note: I only need to check connectivity, not necessarily and entire client-service round-trip.
I Ended up creating a Ping() methods in the service as suggested.
FYI, using simply Open() just didn't work - Open() doesn't raise any exceptions even if the service is offline!
Given the fact that there are so many variables which influence success of a WCF Service call, I tend to add a dummy void KnockKnock()) method to the services to have a real proof if the connection works.
This method can also serve a double purpose: You can call it async to notify the server that he has to be prepared for incoming requests. (Just the initial start-up of the service may take some time.) By invoking the KnockKnock() method the server can start loading the service and give your clients a better initial response performance.
