One line to put after InitializeComponent():

 PreviewKeyDown += (s,e) => { if (e.Key == Key.Escape) Close() ;};

Please note that this kind of code behind does not break MVVM pattern since this is UI related and you don't access any viewmodel data. The alternative is to use attached properties which will require more code.
