When overridden in a derived class, provides code that handles an asynchronous task.
public:
abstract System::Threading::Tasks::Task ^ ProcessRequestAsync(System::Web::HttpContext ^ context);public abstract System.Threading.Tasks.Task ProcessRequestAsync (System.Web.HttpContext context);abstract member ProcessRequestAsync : System.Web.HttpContext -> System.Threading.Tasks.TaskPublic MustOverride Function ProcessRequestAsync (context As HttpContext) As TaskParameters
- context
- HttpContext
The HTTP context.
Returns
The asynchronous task.
Remarks
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).
