)

Type Parameters

The type of the result available through the Task<TResult>.

Parameters

function
Type: System.Func<TResult>
A function delegate that returns the future result to be available through the Task<TResult>.
creationOptions
Type: System.Threading.Tasks.TaskCreationOptions
A TaskCreationOptions value that controls the behavior of the created Task<TResult>.

ArgumentOutOfRangeException

Calling StartNew is functionally equivalent to creating a Task<TResult> 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.
