Silverlight is a technology from Microsoft for developing rich Internet applications (RIA).
Silverlight applications use the Microsoft WCF (Windows Communication Foundation) Framework.
The HTTP requests sent by the Silverlight client to the server often contain binary data that you cannot read. NeoLoad converts these messages into XML, to make designing scenarios easy.
The Silverlight module does not require any configuring and its use is transparent for the user.
The following diagram shows how the Silverlight module functions during recording:
The binary data exchanged between the client and server transit through the recording proxy. It is during this transit that the Silverlight module analyzes and decodes the requests. Once they have been converted into XML, the requests are inserted in the project.
The following diagram shows how the Silverlight module functions during test runtime:
The variables in the XML request are calculated and the module engine converts the XML into binary data, which is then sent to the server. The binary response received is converted into XML, after which the validations and Variable Extractors in the played request are executed.
