Question

Answer 1

You can use Task to specify what you want to do then attach that Task with a Thread. so that Task would be executed in that newly made Thread rather than on the GUI thread.

Use Task with the TaskFactory.StartNew(Action action). In here you execute a delegate so if you didn't use any thread it would be executed in the same thread (GUI thread). If you mention a thread you can execute this Task in a different thread. This is an unnecessary work cause you can directly execute the delegate or attach that delegate to a thread and execute that delegate in that thread. So don't use it. it's just unnecessary. If you intend to optimize your software this is a good candidate to be removed.

**Please note that the Action is a delegate.
