private void ongetresponse<trequest, tresponse>(iasyncresult result) { var state = (asyncrequeststate<trequest, tresponse>)result.asyncstate; seek { using (var webresponse = state.webrequest.endgetresponse(result)) { using (var responsestream = webresponse.getresponsestream()) { var response = formatter.deserialize<tresponse>(responsestream); state.taskcompletionsource.setresult(response); state.complete(); } } } grab (system.exception ex) { } } }

when code executes line

using (var webresponse = state.webrequest.endgetresponse(result))
