I’m developing applications using the MVVM pattern on the WPF platform and I can’t figure out how to use commands that are directly related to the View in the ViewModel so that it doesn’t break the pattern. I ran into a problem when I tried to make an authorization window that implied hiding this window after successful authorization, or for example, I need to use animation, but I don’t want to develop it in XAML code, so I wrote C# code and placed it inside the View code, even though it violates the pattern. Please share your development experience with this pattern

To solve this problem, I violated the MVVM pattern and placed code that is responsible only for visual effects inside the View
