Allows you to make properties execute the PropertyChanged event, with less ugly code.

ViewModelNotifier.cs

public class ViewModelNotifier : INotifyPropertyChanged {
	private Dictionary<String, Object> propertyValues = new Dictionary<String, Object>();
	public event PropertyChangedEventHandler PropertyChanged;

	protected void SetProp<T>(T value, [CallerMemberName] string property = null) {
		propertyValues[property] = value;
		OnPropertyChanged(property);
	}
	protected T GetProp<T>([CallerMemberName] string property = null) {
		try {
			return (T)propertyValues[property];
		} catch (Exception) {
			return default(T);
		}
	}
	
	protected void OnPropertyChanged(string propertyName) {
		PropertyChangedEventHandler handler = PropertyChanged;
		if (handler != null)
			handler(this, new PropertyChangedEventArgs(propertyName));
	}
}

/* Example Usage:
class model : ViewModelNotifier {
	public String TextBoxText { get { return GetProp<String>(); } set { SetProp(value); } }
}*/
