Silverlight control blank when moved to production server

[EvanBossett]

I have developed a .NET application using Visual Studio 2010 and the ESRI Silverlight "ArcGIS API for MS Silverlight-WPF 2.1".  It works fine on my local development machine in debug mode.  However, when i deploy the application and try to access the ASPX page w/ the silverlight XAP in it, it just loads as a blank white silverlight (if i right click, i get the "Silverlight" menu).  However, nothing else shows up.

Any tips?

Thank you

Did you add the mime type for .xap files to your webserver?
