XAML Data Binding and MVVM Basics (.NET MAUI, WPF, UWP, Xamarin.Forms)

Summary

The video discusses common data binding mistakes and best practices in MVVM and XAML development for cross-platform .NET technologies like Xamarin, MAUI, and WPF. The presenter, James, walks through a viewer-submitted code example highlighting key issues such as missing property getters and setters, and the importance of public properties for effective data binding. The practical takeaway is to ensure data-bound properties have public getters and setters, use two-way binding, and validate data context to enable seamless interaction between the user interface and underlying view model.
