The second argument passed to the beginMethod delegate.
The third argument passed to the beginMethod delegate.
An object containing data to be used by the beginMethod delegate.
An object that controls the behavior of the created task.
Return ValueType: System.Threading.Tasks.Task<TResult>
The created task that represents the asynchronous operation.
The type of the second argument passed to beginMethod delegate.
The type of the third argument passed to beginMethod delegate.
