	Task<TSource>^ task,

)

[<ExtensionAttribute>]
static member Select : 
        task : Task<'TSource> * 
        continuationAction : Action<Task<'TSource>> -> Task 

Parameters

task

Type: System.Threading.TasksTaskTSource
The antecedent task.

continuationAction

Type: SystemActionTaskTSource
The continuation action to execute when task completes successfully.

Type Parameters

TSource

The type of the result produced by the antecedent TaskTResult.

Return Value

Usage Note

This code implements support for the following construct without requiring the use of /.

TSource source = await task.ConfigureAwait(false);
continuationAction(task);

If the antecedent task is canceled or faulted, the status of the antecedent is directly applied to the task returned by this method; it is not wrapped in an additional AggregateException.

Notes to Callers
Since the continuation is executed synchronously, this method should only be used for lightweight continuation actions. For non-trivial continuation actions, use ThenTSource(TaskTSource, FuncTaskTSource, Task) instead.
