TaskFactory<TResult>::StartNew Method (Func<TResult>^, TaskCreationOptions)

.NET Framework (current version)

Creates and starts a task.

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

Syntax

public:
Task<TResult>^ StartNew(
	Func<TResult>^ function,
	TaskCreationOptions creationOptions
)

Parameters

function: Type: System::Func<TResult>^
A function delegate that returns the future result to be available through the task.

creationOptions: Type: System.Threading.Tasks::TaskCreationOptions
One of the enumeration values that controls the behavior of the created task.

Return Value

Type: System.Threading.Tasks::Task<TResult>^

The started Task<TResult>.

Exceptions

Exception	Condition
ArgumentNullException	The function argument is null.
ArgumentOutOfRangeException	The creationOptions parameter specifies an invalid value.

Remarks

Calling StartNew is functionally equivalent to creating a task by using one of the Task<TResult> constructors and then calling the Start method to schedule it for execution.

However, unless creation and scheduling must be separated, StartNew is the recommended approach for both simplicity and performance.
