[ This article is for Windows Phone 8 developers. If you’re developing for Windows 10, see the latest documentation. ]

Creates and starts a Task.

Namespace:  System.Threading.Tasks
Assembly:  mscorlib (in mscorlib.dll)

public Task StartNew(
	Action action,
	CancellationToken cancellationToken
)

Parameters

action
Type: System.Action
The action delegate to execute asynchronously.
cancellationToken
Type: System.Threading.CancellationToken
The CancellationToken that will be assigned to the new task.

Calling StartNew is functionally equivalent to creating a Task using one of its constructors and then calling Start to schedule it for execution. However, unless creation and scheduling must be separated, StartNew is the recommended approach for both simplicity and performance.
