What are the differences between WPF MVVM and MVC?

What are the differences between WPF MVVM and MVC?

WPF MVVM (Model-View-ViewModel) focuses on separating the UI from the business logic, while MVC (Model-View-Controller) separates the application into three interconnected components. MVVM is more suited for data binding in WPF applications.

Can you explain how data binding works in MVVM?

In MVVM, data binding allows the View to automatically reflect changes in the ViewModel. This is achieved through properties in the ViewModel that implement INotifyPropertyChanged, notifying the View of any changes.

Which pattern is better for large applications?

MVVM is often preferred for large applications, especially in WPF, due to its support for complex data binding and easier unit testing. MVC can also work well, but it may require more boilerplate code for data handling.

Are there any performance differences between the two?

Performance can vary based on implementation, but MVVM may introduce overhead due to data binding. However, it often results in cleaner code and better maintainability, which can outweigh performance concerns.
