* Application.installstatechanged-Events that are triggered when the dependent state of the running outside the browser has changed
* Application.installstate-related state of running outside the browser [System.Windows.InstallState enum]
* notinstalled-run in browser
* Installing-Install to Desktop
* Installed-run outside the browser
* installfailed-Error occurred during installation to desktop
* Application.isrunningoutofbrowser-whether the current program is started from outside the browser
* Application.install ()-Install the Silverlight program outside the browser (uninstall can only be uninstalled by right-clicking the menu)
* Application.checkanddownloadupdateasync, application.checkanddownloadupdatecompleted-a pair of asynchronous methods/events, for updating a browser running Silverlight Program (Download a new version from the server)
*
* Enable OOB: Right-click-> properties on Silverlight Project-> Silverlight-> Select Enable running application out of the browser
* Configure OOB: Right-click-> properties on Silverlight projects-> Silverlight-> Out-of-browser settings can be set on the related parameters of "run out of browser" (or you can manually modify Prope Rties/outofbrowsersettings.xml)
*/

/*
* Debug the Silverlight program in OOB mode: Enable OOB mode, set the Silverlight project as the startup project, and then run
*/
