Silverlight Client for Facebook updated for Silverlight 4 release

Yet again, we’ve updated the Silverlight Client for Facebook for the Silverlight 4 release version.  In order to use the updated one, you must follow these instructions:

• First, uninstall the previous version you have.  This can be done in Add/Remove Programs on Windows or by just deleting the app on Mac.
• Ensure you have Silverlight 4 installed.  If you are using the development tools and have installed Silverlight 4 developer tools, that’s fine.  If you are not a developer, visit http://microsoft.com/getsilverlight to get the latest Silverlight 4 version (4.0.50401.0).
• After you have Silverlight 4 installed, visit the app page and install it.

You should be good after this! 

So why so many uninstall/re-installs!?  I thought you had an auto-update mechanism!

We do!  With Silverlight 4 trusted applications, the update mechanism requires that your applications be signed in order to use the auto-update APIs.  We wanted to wait until SL4 released in order to provide a signed version (and our internal signing process didn’t allow signing the beta).  Now that we have a signed version, you’ll be prompted when an update has been installed for the app.  For more details on signing your Silverlight applications see:

Hope this helps!
