The HTTP context.
The asynchronous task.
To create a custom handler for an asynchronous task, override the ProcessRequestAsync method.
This method stores in the task it returns all non-usage exceptions that the method's synchronous counterpart can throw. If an exception is stored into the returned task, that exception will be thrown when the task is awaited. Usage exceptions, such as ArgumentException, are still thrown synchronously. For the stored exceptions, see the exceptions thrown by ProcessRequest(HttpContext).
