I'm having trouble with data binding in my MVVM application. What should I check?
First, ensure that your ViewModel properties are properly notifying the view of changes. Are you using INotifyPropertyChanged?
Yes, I implemented INotifyPropertyChanged, but the UI still doesn't update.
Check if the bindings in your XAML are correctly set up. Are you using the correct DataContext for your view?
I think the DataContext is set correctly, but I'm not sure how to verify it.
You can debug by setting a breakpoint in your ViewModel's constructor and checking if it's being hit when the view loads.
