#38 – The Application Class

Application is a class that represents a WPF application running as a standalone client application in Windows.  Each running application contains at most a single instance of Application.

WPF applications created using the Visual Studio 2010 wizard will contain the definition of the Application object in the App.xaml file.

<Application x:Class="WpfApplication9.App"
     xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
     xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
     StartupUri="MainWindow.xaml">
   <Application.Resources>

   </Application.Resources>
</Application>

The Application object is responsible for:

• Managing application lifetime (e.g. responding to startup/shutdown events)
• Window, property and resource management
• Command-line processing
• Navigation
