Answer 1

MVVM is a design pattern whose intent is to help you providing a clean separation of concerns between the user interface controls and their logic. One of the benefits this pattern brings is that you can test your application logic without the view, i.e. you run unit tests against the view model class only.

There are three core components in the MVVM pattern: the model, the view, and the view model. Each serves a distinct and separate role. Please refer to the following pages for more information about the MVVM pattern and how to implement it in WPF:

One important difference is that almost every team and every developer uses MVVM.

If you don't, then getting a new job using wpf is going to be tough.

They use mvvm because it's a better way to work.

.

MVVM separates out code from the view so it can be worked on separately, tested separately and gain the usual benefits from separation of concerns.
