Thank you very much for your reply, I already asked this question with proper code in Microsoft question and answer forum.

Here is the link :

I can not understand what you saying by "You will probably need to define your own class which wraps the AudioDevice class". Any code guide will a great help.

Love the effort you put in to answer my question, but still I am unable to understand. I already asked this question with full code and proper explanation on Microsoft question and answer forum but I don't get any satisfied answer from there.

Here is the link :

Make sure that you read this question throughly, and give your decent code answer.

Again brilliant answer, I fully understand, ultimately what you say is option 2 is really better because observable collection will cascade to the ListCollectionView and automatically update the dropdown contents.

but any code guide on option 2? How can I declare an observable collection as itemsource for a ListCollectionView?

By the thank you very much for your crystal clear theory answer.

Your answer is outstanding, I already understand the theory part. In your first option you say, Whenever I get an updated devices list I need to update the ComboBox with a ListCollectionView and assigning it to the cmb1.ItemsSource.

Suppose, I open the ComboBox dropdown and at that time any of the item from the device list is unplugged or remove from the computer, How can I detect that?

I also understand your second option but I don't know how to apply it in code. I wish you can give me proper code example.
