Starts a Windows Presentation Foundation (WPF) application.
Assembly: PresentationFramework (in PresentationFramework.dll)
Run is called to start a WPF application. If you define your Application using markup, or markup and code-behind, Run will be called implicitly. However, if you define your Application using code, you will need to explicitly call Run.
When Run is called, Application attaches a new Dispatcher instance to the UI thread. Next, the Dispatcher object's Run method is called, which starts a message pump to process windows messages. Finally, the Dispatcher object calls the Application object's the OnStartup method to raise the Startup event. Consequently, the application execution model has been established by the time you handle Startup, at which point the application is considered to be running.
An application stops running when Shutdown is called; the value of the ShutdownMode property determines when Shutdown is called, and whether it happens automatically or you need to explicitly call it.
