I am very pleased to tell you that we have just deployed the QFE to support Silverlight 2 Beta on the Silverlight Streaming service (SLS in the rest of this post).

You could already upload XAP files to SLS since we had updated the “allow list” for SLS, now you can instantiate your app from SLS. It is important to note that the SLS manifest is *not* the same thing as the new appManifest introduced with the XAP concept in Silverlight 2 Beta.

The two major changes to the SLS manifest.xml are the following:

1. You can specify <version>2.0</version> and it will require Silverlight 2 Beta to be present on the client machine to run the app
2. You can specify <source>yourApp.xap</source> and it will actually understand what to do with it
