Comparison to MVC
- Similarity: You can think of VM in MVVM is equivalent to C in MVC
- MVC format is specifically designed to create a separation of concerns between the model and view
- MVVM format with data-binding is designed specifically to allow the view and model to communicate directly with each other
- ViewModel isn’t a controller, instead acts as a binder that binds data between the view and model
- Xamarin.Forms (Prism)
- ASP.NET Core razor pages
