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.Task

Public MustOverride Function ProcessRequestAsync (context As HttpContext) As Task

Parameters

context: HttpContext

The HTTP context.

Returns

Task

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).
