Use Internal WPF to host web applications
Note
Because support for Internet Explorer 11 is deprecated, support for IE Process has also been deprecated in Unified Service Desk. For information: Deprecation announcement.
The Internal WPF browser control uses the WpfBrowser component, which is based on the Windows Presentation Foundation (WPF)WebBrowser control, to host the webpages in Unified Service Desk. This browser control is the traditional method of hosting controls in Unified Service Desk. It uses the security subsystem in Internet Explorer and Windows to allow the hosted application to operate the browser functionality in the same mode as the application without changing the Internet Explorer settings, and therefore reduces the security of Internet Explorer for applications outside of Unified Service Desk. While there are advantages, occasionally you may find that you need the features of an Internet Explorer add-in or a feature in the native browser that may not be supported in this browser control, and you should use the IE Process browser control instead.
