In this video, I explain why the MVVM (Model-View-ViewModel) pattern is needed in WPF applications. I start by demonstrating how code is structured without MVVM, highlighting the issues of tightly coupled code. Then, I show how to separate concerns using a ViewModel, implement INotifyPropertyChanged for two-way binding, and leverage commands to handle user interactions properly. Finally, I introduce the Relay Command pattern for better code reusability.

🔹 Topics Covered:
✅ Code without MVVM – Understanding the problem
✅ Creating a ViewModel for separation of concerns
✅ Implementing INotifyPropertyChanged for automatic UI updates
✅ Using Commands for button clicks instead of code-behind
✅ Introducing RelayCommand for reusable command logic
