A fast way to apply styles to your controls is to right-click on a control on the Microsoft Visual Studio XAML design surface and select Edit Style or Edit Template (depending on the control you are right-clicking on). You can then apply an existing style by selecting Apply Resource or define a new style by selecting Create Empty. If you create an empty style, you are given the option to define it in the page, in the App.xaml file, or in a separate resource dictionary.
