Thread Safety

Unlike most of the members of the Task class, this method is not thread-safe.

The Task class implements the IDisposable interface because internally it uses resources that also implement IDisposable. However, particularly if your app targets the .NET Framework 4.5 or later, there is no need to call Dispose unless performance or scalability testing indicates that, based on your usage patterns, your app's performance would be improved by disposing of tasks.
