Load Testing and Monitoring Microsoft Silverlight Applications

You use Microsoft Silverlight!

Microsoft Silverlight® is an Internet browser plug-in for developing rich Internet applications, incorporating animation and audio and video feeds. Silverlight, Microsoft’s solution for rich Internet applications, uses Windows Communication Foundation (WCF) for its browser-server communication.

Silverlight Support

Silverlight applications may rely on .Net binary XML to communicate with the server: MC-NBFX (binary XML) or MC-NBFS (binary SOAP). Since this is a binary protocol, testing and monitoring such Silverlight applications requires this protocol to be specifically supported. Neotys’ Silverlight support allows you to:

  • Record the .Net binary XML to be played back.
  • Extract/replace XML binary data during testing and monitoring in order to variabilize the calls (the data is presented in XML format in the scenario).
  • Automatically handle the session IDs used by Silverlight.
