Hi Miky,
Yes, it is possible to apply skin to an application. If your application contains only one Window then you can set the Skin to that particular window alone. This will apply the skin to all the objects present in that window. Please refer the below given XAML code snippet for applying the skin to the Window. Otherwise, If your application have two or more windows, you have to set the skin for each window explicitly in the application.
XAML Code :-
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:syncfusion="http://schemas.syncfusion.com/wpf"
Title="Skin Manager Demo" Height="500" syncfusion:SkinStorage.VisualStyle="Office2007Blue">
