static member DoOperationAsync : 
        operation : Func<IAsyncContext, 'TResult> * 
        canceledResult : 'TResult * 
        asyncConfig : TaskConfig -> Task<'TResult>

Parameters

operation FuncIAsyncContext, TResult: The operation to be executed.
canceledResult TResult: The result to be returned by the returned task if the operation has been canceled and ThrowIfCanceled of asyncConfig returns .
asyncConfig TaskConfig: The configuration for the asynchronous operation.

Type Parameters

TResult: The type of the result of the specified operation.
