Hello, I have an intranet site (iis 7.5) that hosts a Silverlight oob application. The site also hosts a wcf service that is used by the oob application.
I use Windows Authentication, primarily to lock down the wcf service, eg <authentication mode="Windows" /> in the web.config. The user lifecycle is like this : a. First time they use their browser to navigate to the host web page. They are prompted for Windows credentials. b. User clicks a button that lets them install it oob. c. Lets say later the user launch the oob app, I pop up a login window and use the supplied windows credentials for subsequent wcf calls until they shut down the app. This works nicely. However, when they launch the app I do the standard App.Current.CheckAndDownloadUpdateAsync() to check for updates. The problem is that it doesn't detect updates. The reason it doesn't detect the update is because of a "401 - Unauthorized: Access is denied due to invalid credentials" on the xap file I can see in Fiddler. This makes perfect sense, I haven't supplied any credentials so why would IIS allow the user to access the new xap file. So, my question is, how can I supply credentials to CheckAndDownloadUpdateAsync() ? Or can someone suggest an alternative? Thank you in advance. Mikala
