Recording Microsoft Silverlight applications

To test the performance of an application that was developed by using Microsoft Silverlight, you can record the application.

Before you begin

HCL OneTest™ Performance supports Microsoft Silverlight 5.

About this task

Microsoft Silverlight communicates with the server in the Windows Communication Foundation (WCF) Binary format. After recording the Microsoft Silverlight application, you can transform the format to XML for better readability and to apply data correlation.


  1. Record the HTTP application as described in Recording an HTTP Test. By default, HCL OneTest Performance transforms the WCF Binary format into XML format.
  2. Optional: If you changed the default setting of HCL OneTest Performance to not transform after the recording, follow the steps in the Transforming binary data in tests topic.
