The Silverlight Streaming API uses standard Hyper Text Transfer Protocol (HTTP) basic authentication (RFC 2617). Your user name is your Silverlight Streaming account ID (not your Windows Live ID) and the password is your Silverlight Streaming account key. The account details can be obtained on the Manage Account page on the Silverlight Streaming administration Web site. All requests must be over SSL (https).

The following C# console application demonstrates the calls required for authentication.

using System;
using System.Net;
using System.IO; 

namespace SilverlightServicesApi
{
 class Program
 {
  static void Main(string[] args)
  {
   // accountId = Silverlight Streaming Account ID
   HttpWebRequest req =
     (HttpWebRequest)HttpWebRequest.Create
     ("https://silverlight.services.live.com/accountId");
   byte[] userPass = Encoding.Default.GetBytes(accountId + ":" + accountsecret);
   string basic = "Basic " + Convert.ToBase64String(userPass);
   req.Headers["Authorization"] = basic; 

   HttpWebResponse resp = (HttpWebResponse)req.GetResponse();
   Stream strm = resp.GetResponseStream();
   StreamReader rdr = new StreamReader(strm);
   string xmlResponse = rdr.ReadToEnd();
  }
 }
}

Before you upload an application to Silverlight Streaming, you must package your application files into file sets. Each file set represents one Silverlight application. For example, a video file set might include the Windows Media file with the video, several small JPG files showing stills from index points within the video, and a copy of the player application to display the video.

All files in a file set must be contained in a single ZIP archive.
