I've created a WPF map control which I've embedded in a Windows Forms control using the ElementHost control. When attempting to load a secured a webmap no sign in window is produced.
At the recommendation of Michael Branscomb, I was able to dig into the source code of the OAuthAuthorizationHandler since it's supplied with the ArcGIS.Runtime.Toolkit. It turns out that the source code assumes that the host application is a WPF application by calling Application.Current to get a hook on the application's Dispatcher and MainWindow. This allows the sign in window to be centered and modal.
var dispatcher = Application.Current.Dispatcher;
Since my application is a Windows Forms application I modified a copy of the OAuthAuthorizationHandler to open the sign in window on it's own thread as a non-modal window if the application is not a WPF application. This works and I've attached the source code if anyone is interested.
My question / concern now has to do with Quartz. At the Devsummit it was stated that Quartz will have better Authentication support. I assume that means more black-boxed. Will I have to, or even be able to, make a similar hack? Or better yet, can the Quartz team look at this issue and add support for non-WPF applications?
