Some information relates to prerelease product that may be substantially modified before it’s released. Microsoft makes no warranties, express or implied, with respect to the information provided here.

public static System.Threading.Tasks.Task RunAsync (this Microsoft.Extensions.Hosting.IHost host, System.Threading.CancellationToken token = default);static member RunAsync : Microsoft.Extensions.Hosting.IHost * System.Threading.CancellationToken -> System.Threading.Tasks.Task<Extension()>
Public Function RunAsync (host As IHost, Optional token As CancellationToken = Nothing) As TaskParameters
- token
- CancellationToken
The token to trigger shutdown.
Returns
The Task that represents the asynchronous operation.
Exceptions
The cancellation token was canceled. This exception is stored into the returned task.
Remarks
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 Run(IHost).
