WPF Dispatcher Queries

Question

Hello ,

I have studied a whole lots on dispatcher , but i have had some queries which i was asked in some interview and want to verify if i am wrong or right.

1) Can we create a ui element at runtime in a different thread in WPF? I am not clear about this question. The first question would be can we create UI elements in a different thread. If yes what would be the dispatcher scenario then.
2) Can we have more than one dispatchers in WPF Application? I think its a NO
3) Can a WPF Application have multiple UI Threads? I think NO
4) If we are launching the form using Form.Show() in WPF, will it launch another dispatcher? Again No
