Updating Silverlight Out Of Browser Application

I have a silverlight out of browser application which will not update when changes are made to my project.

I have added the CheckAndDownloadUpdateAsync() method within the App file and this works fine when running locally however as soon as I host it on my server (IIS 7) it stops updating.

I have tried amending the HTTP header expiration as per http://forums.silverli开发者_如何学JAVAght.net/p/137425/306895.aspx and also ensured that I am passing through annonymous access to the Client bin folder however this still does not work.

Any ideas??

Ok figured this out - I needed to sign the XAP file.

Did this and it now works

You have to sign the XAP (digital sign ) along with a certificate. If elevated trust is enable and you want automatic update in installed application without re-installation, signing the XAP and certification is necessary.
