How do we close and a Silverlight application in silverlight 4

I want to close and a silverlight application on the MenuClick event which I am handling in a helper class...

if (Application.Current.IsRunningOutOfBrowser)
                    Application.Current.MainWindow.Close();

or

HtmlPage.Window.Invoke("close");

is not working.....

So if anyone has a diff solution or corrections to开发者_JAVA技巧 the above approch please answer me...

if (!Application.Current.IsRunningOutOfBrowser)
   HtmlPage.Window.Eval("window.open('','_self');window.close();");

If the app is running in-browser then the browser's rules regarding opening/closing windows will apply. Namely, you can only use a scripted command to close a window that was opened with a scripted command. If the user opened the window then you cannot close it with an Invoke command.

I've never tried to close an OOB app in code so I can't help you on that side of things.
