Manages an application in a XAML design surface that runs in a regular UWP context, compared to the legacy designer which uses the XamlUIPresenter and runs in a Win32 process. The process is required to specify the NoUIEntryPoints-DesignModeV2 DisplayName property in the .APPX in order to be activated successfully in this mode. The launched application will not show up in the TaskBar or TaskView switcher.
