Task Constructor (Action(Object), Object)
Initializes a new Task with the specified action and state.
Assemblies: System.Threading.Tasks (in System.Threading.Tasks.dll)
mscorlib (in mscorlib.dll)
Rather than calling this constructor, the most common way to instantiate a Task object and launch a task is by calling the static TaskFactory.StartNew(Action(Object), Object) method. The only advantage offered by this constructor is that it allows object instantiation to be separated from task invocation.
