With today's release of the Silverlight 1.0 RC and 1.1 Refresh, I've updated the Silverlight samples I own to run on the new bits. Specifically, I've uploaded the migrated source code and recompiled binaries for the team's Silverlight Airlines Demo, my Simple XPS Viewer Demo, and my Silverlight Surface Demo. Because the Silverlight 1.1 Refresh replaces the earlier 1.1 Alpha, the existing source and demo URLs remain the same and simply point to the new content.
The 1.1 Refresh's breaking changes from the 1.1 Alpha build we've all been using before today are documented in the SDK. The migration of the these samples was pretty simple and required very little code change. For the benefit of others migrating Silverlight apps, here are the specific incompatibilities I encountered along with the fix for each:
Additionally, a security-related change to the Downloader object now blocks access to file:// URLs. This means that the XPS Viewer and Surface demos will only be able to access their resources (images, files, etc.) when the host page is loaded from a web server. Specifically, loading Default.html from Explorer or by hitting F5 to run the project in Visual Studio will now result in an error message like the following:

To re-enable debugging for the XPS Viewer and Surface demos, I recommend the following steps which add a web site project to Visual Studio and access the demo page via the included Visual Studio Development Web Server (which uses http:// URLs and works fine). While there are other ways to work around the file:// restriction, I'm suggesting this approach because it automatically references the project files, doesn't require creating additional directories or copies of project files, and doesn't require getting involved with IIS. To enable debugging:
Okay, enough with the boring details - go get the Silverlight 1.1 Refresh and have some fun with it! :)
