XAP Caching in Out of Browser (OOB) Silverlight Applications

Question

When a Silverlight 4 application is installed and run out-of-browser (OOB), is it possible to have the application automatically recognize updates to the .xap file (and either automatically install or prompt the user to update)?

If you access the application from it's original web URL, you are automatically given the latest & greatest (based on your settings).

But once I install the application to run OOB, it does not seem to recognize updates to the original .xap file, nor does there seem to be any way to trigger an update (outside of right-clicking, uninstalling, and then going out to the website to get the latest version).

Thanks in advance

Answer 1

This is something your application needs to implement. However the Application object provides a simple means to acheive this via the CheckAndDownloadUpdateAsync method.
