wpf mvvm commands C#

I've looked through the documentation and I'm still confused about I’m experiencing a frustrating issue with command bindings in my WPF application using .NET 6... I have a button that should trigger a command in my ViewModel, but it doesn't seem to fire when clicked. I've set up the command like this: ```csharp public class MyViewModel : INotifyPropertyChanged { public ICommand MyCommand { get; private set; } public MyViewModel() { MyCommand = new RelayCommand(ExecuteMyCommand, CanExecuteMyCommand); } private void ExecuteMyCommand(object parameter) { // Command logic here } private bool CanExecuteMyCommand(object parameter) { return true; // Enable command } } ``` In my XAML, the button is defined like this: ```xml <Button Content="Click Me" Command="{Binding MyCommand}" /> ``` Despite this setup, clicking the button does nothing, and I am not seeing any exceptions in the output window. I’ve verified that the DataContext for the view is set correctly and that the ViewModel initializes without any issues. Additionally, I’ve checked that the RelayCommand implementation is correct and the CanExecute method is returning true. I also tried using the Visual Studio Live Visual Tree to inspect bindings, and it confirms that the command is not hooking up properly, even though the DataContext is correct. I’m starting to suspect it might be related to the threading model since I’m performing some async operations elsewhere, but I’m not sure how that could affect command execution. Has anyone encountered a similar issue, or does anyone have suggestions on what I might be missing? Is there a better approach?
