Synchronizing WPF UI Elements Using Event Bindings - TextBox Placeholder WPF and Async Yield Return

Learn how to create responsive and interactive user interfaces in WPF using .NET Core 7. Explore techniques for synchronizing UI elements, implementing TextBox placeholders, and leveraging asynchronous programming. Discover how to use ObservableCollection for automatic ListBox synchronization, handle thread-safe operations with Random.Shared, and manage UI access from sub-threads. Master the implementation of data binding with ObservableObject and ObservableProperty from Microsoft Toolkit MVVM. Gain insights into proper DataContext setting, automatic property change notifications, and advanced async programming techniques including yield return, Task.FromResult, and async ForEach loops.
