Overloads
ExecuteAsync(IExecutionStrategy, Func<Task>)
Executes the specified asynchronous operation.
public static System.Threading.Tasks.Task ExecuteAsync (this Microsoft.EntityFrameworkCore.Storage.IExecutionStrategy strategy, Func<System.Threading.Tasks.Task> operation);static member ExecuteAsync : Microsoft.EntityFrameworkCore.Storage.IExecutionStrategy * Func<System.Threading.Tasks.Task> -> System.Threading.Tasks.Task<Extension()>
Public Function ExecuteAsync (strategy As IExecutionStrategy, operation As Func(Of Task)) As TaskParameters
- strategy
- IExecutionStrategy
The strategy that will be used for the execution.
Returns
A task that will run to completion if the original task completes successfully (either the first time or after retrying transient failures). If the task fails with a non-transient error or the retry limit is reached, the returned task will become faulted and the exception must be observed.
Remarks

A function that returns a started task.
- cancellationToken
