Interaction with the Silverlight Browser: Install the Silverlight program locally

Overview

Application. InstallMethod
Try to install the applicationProgramSo that the application can run outside the browser.
This method can only work in the event handler of the event initiated by the user, and can work normally only when the Application List is correctly configured to enable external browser support.
If these conditions are not met, this method returns false and the installation dialog box is not displayed.
If the application requires a higher level of trust, this method returns true before the installation dialog box is displayed.

Application. installstatechangedEvent
Occurs when the value of the installstate attribute is changed.

Application. isrunningoutofbrowserAttribute
Gets a value indicating whether the application is started out of the browser.
