Namespace: Dundas.BI
Assembly: Dundas.BI.Core (in Dundas.BI.Core.dll) Version: 2.0.0.0 (26.2.0.1000)

Syntax

Task<TResult> SpawnTask<TResult>(
	string name,
	Func<TResult> func,
	GroupCancellationToken? cancellationToken
)

Function SpawnTask(Of TResult) ( 
	name As String,
	func As Func(Of TResult),
	cancellationToken As GroupCancellationToken
) As Task(Of TResult)

generic<typename TResult>
Task<TResult>^ SpawnTask(
	String^ name, 
	Func<TResult>^ func, 
	GroupCancellationToken^ cancellationToken
)

abstract SpawnTask : 
        name : string * 
        func : Func<'TResult> * 
        cancellationToken : GroupCancellationToken -> Task<'TResult>

Parameters

name String: A name which will be assigned to the spawned operation (used for diagnostic purposes).
func FuncTResult: The function to invoke asynchronously.
cancellationToken GroupCancellationToken: The cancellation token.

Type Parameters

TResult: The type of object returned by the task.

Return Value

TaskTResult
A task object representing the asynchronous operation.

Exceptions

Exception	Condition
ArgumentNullException	func is .

Remarks

The spawned task will have the same caller context as the code which called this method. Therefore, if the caller context of the calling method is disposed before the body of the spawned task has completed, the task may lose its caller context during execution. If you want to ensure that the caller context remains valid for the entire duration of the spawned task, because the task may outlive the calling method's context, use QueueBackgroundTask(Action, TimeSpan, CancellationToken).
