Once a Silverlight application has been installed as an out-of-browser application, I know I can update it by calling the Application.Current.CheckAndDownloadUpdateAsync() method. This will check the URL where the XAP was originally downloaded and update if necessary.

But what if, somewhere in the future, I would want or need to change the url of the XAP? The domain name changes, the location on my site, etc.

Is there a way of indicating where the OOB application should check for the update?

Now I know of the /origin property, but as far as I know, there’s no way to set this when you let the user just install it by clicking on a button on your site (or right clicking in the application). Also, I don’t know of a way of changing it at a certain point in time. Other than letting the user do it manually, that is. But that’s not very user-friendly.

If it is entirely not possible, maybe a redirect could do the trick?

So is there a way to programmatically define/change the URL of a XAP?

    You can not change origin url for installed OOB application. Not without asking user to uninstall and re-install application from new location. It is not all that user friendly, but it is transparent to the user.

    Ideally origin url should not change during life time of the application. Using server side url rewriting (maybe redirecting too) should be fine if you would like to move xap file around. If changing domain name is unavoidable you could push an update to the users that reminds them that application moved to different domain and it needs to be re-installed.
