The best WPF tutorials on youtube.

Really like the way you zoom in on the code. I tried following one of your earlier series ( the Vending Machine). It is much easier to read the code to transcribe into my project. It is much easier for me to learn by typing out the commands as opposed to cut and paste . Thank you for doing all of these videos.

I love Your video

Perhaps this will become clear later in the playlist, but I don't follow the decision to have a BookViewModel and a ContactsViewModel-- my inclination is simply that each View gets its own ViewModel. Here, it's as if the BookViewModel was preemptively divided, where a ContactsViewModel was created separately and added as a property to BookViewModel. I don't follow how or why that decision was made. Perhaps it will become clear later, but this would have been better explained in this video.

Zero explaining. Useless lessons, with the same effort I could just open random project in github and don't understand any source code.
