Issue in Async wcf proxy

Question

I have created async proxy for my wcf application, calling the method first time

ServiceClient serviceClient = new ServiceClient(); serviceClient.GetDataAsync(5);

doesnt invoke the service.

I need to use SetNextstatement in IDE, second time to make this works.

Pls help me to find the root cause of this issue. Thanks

Async invokation doesn't guarantee immediate start of invokation. It starts the process of invokation somewhere in another thread. The actual service call happens after some time (after preparations are finished), in your case it happens somewhere it between stepping to next statement.
