Forcing browsers to reload Silverlight xap after an update

Question

I have a Silverlight control packaged up and deployed to a SharePoint web part. I\'m having trouble with the browser loading new versions of the control after I push an upd

t’s not very uncommon to run into .XAP caching, which means that every time you deploy a new version of the Silverlight application, the browser does not download the updated .XAP file.

One solution could be to change the IIS properties. You can turn the “Enable Content Expiration HTTP header” option on for your .XAP file by following these step:

Open IIS Manager
Go to “Default Web Site” and find web site for your Silverlight project.
Find the .XAP file under ClientBin.
Go to the properties page of the .XAP file, on HTTP Headers Tab, Turn on “Enable Content Expiration”, click the “Expire Immediately” radio button.
Save the changes.

This way the latest .XAP (only if there is a latest .XAP file) will get downloaded when you refresh your page without having to close the browser.

Hope this helps!
