Hi, how do I test the state of my proxy before making calls to my WCF service.

I have a duplex channel created using a duplex channel factory.

Before making any calls to the server I want to check the state of the proxy object created from the channel factory.

I saw this in a book... (to be used in immediate window)

? ((ICommunicationObject)flsProxy).State

But it gave this exception...

Cannot obtain fields or call methods on the instance of type 'System.ServiceModel.ICommunicationObject' because it is a proxy to a remote object.

Would be grateful for any ideas how this can be tested, or is it better to just catch exceptions.

Thanks.
