How can I set my web browser version emulator when my app is running
I use this code

private static void WebBrowserVersionEmulation(int browserEmulationMode)
       {
           const string BROWSER_EMULATION_KEY =
           @"Software\Microsoft\Internet Explorer\Main\FeatureControl\FEATURE_BROWSER_EMULATION";
           //
           // app.exe and app.vshost.exe
           String appname = Process.GetCurrentProcess().ProcessName + ".exe";
           //
           // Webpages are displayed in IE9 Standards mode, regardless of the !DOCTYPE directive.
           //const int browserEmulationMode = 9999;

           RegistryKey browserEmulationKey =
               Registry.CurrentUser.OpenSubKey(BROWSER_EMULATION_KEY, RegistryKeyPermissionCheck.ReadWriteSubTree) ??
               Registry.CurrentUser.CreateSubKey(BROWSER_EMULATION_KEY);

           if (browserEmulationKey != null)
           {
               browserEmulationKey.SetValue(appname, browserEmulationMode, RegistryValueKind.DWord);
               browserEmulationKey.Close();
           }
       }

It works onyl If I restart myApplication.
I don't want to restart my App.
