Can a Silverlight video player play a wmv from an Azure blob?

Here is a simple scenario:

An Azure blob contains a wmv video. The blob is public. When I point my browser to the blob, Windows Media Player starts and starts streaming the video.

However, if I point a Silverlight MediaElement to the 开发者_Go百科same URL, it does not play anything.

Why would that be?

Launch a tool (like one from Cerebrata or any other) that let's you view the content type of the media stored in Azure blob storage.

My guess is that the content type is blank in Azure blob storage and the Silverlight MediaElement doesn't know what to do with it.
