Sure.
All you have to do is mark:

C#

[OperationContract(IsInitiating=false, IsTerminating=true)]
public void CloseSession()
{

}

And session is gone...

You can also set method that's allowed to create session:

C#

OperationContract(IsInitiating=true, IsTerminating=false)]
public void StartSession()
{

}

Use google for more info. :)

You can set the request objects to NULL and then call the [proxyclient].close() method. It will close the current session.

Also, before calling the close method, check if the service is in faulted state. if it so, call the abort method and then call the close method.

Best way is to enclose within USING block. This will ensure that the client is closed when the control completes the execution of USING block.
