The new Silverlight 3 beta includes the ability to run Out-of-Browser applications. The demos so far show this only inside a special frame. Does anyone know how I can run Siverlight 3 controls inside a (WPF) application?
R – Silverlight 3 – Can I run Out-of-browser inside another application
No, you can not embed out-of-browser silverlight into WPF. The sllauncher.exe standalone frame has a special handler for the offline://(hostname).(revision)/ url given to it to allow the app to have all the features of out-of-browser mode (like extra keyboard access). Unless you can find a way to embed this app into your app, you won't be able to get out-of-browser; if you know some way to do this the address for this app is:
C:\Program Files\Microsoft Silverlight\3.0.40307.0\sllauncher.exe
As others have said, however, you can embed a silverlight control inside of an html page and that inside a WebBrowser element. Be cautious with this method, however, since there is currently no x64 support for Silverlight and if you absolutely must do this make sure to compile specifically for x86.
