Launching Silverlight from a browser application programmatically

Question

I am trying to use SLLAUNCHER.EXE to launch the installed SL Out-of-Browser App. The MyApp launch icon on the desktop simply disappears after starting below. If I try it without rewriting, nothing will happen.

I use this article as a guide:

Any suggestions would be appreciated.

static void Main(string[] args) { string sllauncherPath = string.Format("{0}\\Microsoft Silverlight\\sllauncher.exe", Environment.GetFolderPath(Environment.SpecialFolder.ProgramFiles)); string originUri = @"http://localhost:52878/ClientBin/MyApp.xap"; string xap = "MyApp.xap"; string arg = string.Format(@"/emulate:""{0}"" /origin:""{1}"" /overwrite", xap, originUri); var startInfo = new ProcessStartInfo { CreateNoWindow = false, UseShellExecute = false, RedirectStandardOutput = false, FileName = sllauncherPath, Arguments = arg }; var process = Process.Start(startInfo)) }

Are you using a 64 bit machine? http://social.msdn.microsoft.com/Forums/en-US/silverlightcontrols/thread/abedb9dc-d471-4d82-8a20-45f98671cac9

May also help: Here is how I reboot from my SL OOB applications after I find that the update is complete:

 ''put this in your App.xaml.vb[.cs] and call DoRestart Public Shared Sub DoRestart() StartAgain() Application.Current.MainWindow.Close() End Sub Public Shared Sub StartAgain() If Not [String].IsNullOrEmpty(GetSLLauncherCommand) Then Using shell = AutomationFactory.CreateObject("WScript.Shell") shell.Run(GetSLLauncherCommand) End Using End If End Sub Public Shared Function GetSLLauncherCommand() As String Dim desktopPath As String Dim SLLauncherCommand As String = "" Using wShell As Object = AutomationFactory.CreateObject("WScript.Shell") desktopPath = wShell.SpecialFolders("Desktop") End Using Using shell As Object = AutomationFactory.CreateObject("Shell.Application") Dim DesktopFolder As Object = shell.[NameSpace](desktopPath) Dim DesktopItems As Object = DesktopFolder.Items() For Each item In DesktopItems If item.IsLink Then 'this is a shurtcut Dim fileName As String = item.Name.ToLower() If fileName.Contains("!!!<PART OF YOUR SL APPS SHORCUT NAME>!!!!") Then Dim link = item.GetLink() SLLauncherCommand = """" & Convert.ToString(link.Path) & """ " & Convert.ToString(link.Arguments) End If End If Next End Using Return SLLauncherCommand End Function 

You can try to adapt the code for your application other than SL!
