Now combine this into a zip at the root of the zip and not in a directory. Once you do that log into the Silverlight streaming site and click ‘Manage Application’ and then click ‘Upload a Silverlight Application’.
Give the application and name and browse to your zip. If anything is missing such as a manifest.xml or you have left the html file or something in the file you will get an error.
This window gives you all the information you need to actually link to your uploaded Silverlight Streaming hosted application.
