Check and download Update

Question

I have read several posts about

App.Current.CheckAndDownloadUpdateAsync();

It returns false for me no matter what I do.  There is never has an update.  It has elevated trust and it also has a signed xap file with a valid code signing certificate.  For some reason it just doesn't see the update.

By the way it is out of browser.

Any other suggestions?

 

Answer 1

Hi Chris,

handle the CheckAndDownloadUpdateCompleted event.

If it doesn't help, please check whether a new version of Silverlight is needed which the user hasn't installed or an update changes the application to reqire elevated trust.  When these exceptions happen, you can alert the user to open the application's host Web site, triggering your HTML-based Silverlight upgrade experience.

For details about it, please check the link below:

Answer 2

I have that event it returns false no matter what I do.

Answer 3

By the way the xap is signed.  I have to have elevated trust because I have a few peocedures with some unsafe code in it.  So I cannot just remove elevated trust from the project.

Thanks

Still having problems with getting this to work, is there another way or a workaround?

Answer 5

Make sure that you have all the certificates corretly installed (you can verify by enabling In browser trust and check that the application receives elevated permissions).

Do you run your application on a https address?  If you do and you use a "home made certificate"/is your own CA then you should make sure that the certificates' CRL URI's can be reached.

Answer 6

Apps are on just an http server. My certificates are installed.  I must be missing something simple.
