Performance Testing of ASP.NET application that uses Silverlight

Jan 16, 2015 at 4:36 AM

I need to create the web performance test script for ASP.NET application that uses Silverlight. I am using Visual Studio Ultimate 2013. Silverlight plugin in enabled in my browser IE9 and the application works fine manually.

After recording part of the test flow on the application (eg. Home Page), I see values like "????????????d?6??{??M5?"}g??t" in "Form Post Parameter". I also see request for SL.Launcher.xap in the script. I have tried to run the Launcher URL independently on browser and it asks me to download/run the silverlight plugin. Not sure why this request is generated since the application works perfectly on my browser.

I have also tried to get the requests from Fiddler and then export them to visual studio. But even in Fiddler i see similar encoded/encrypted values in request + response body.

I need to get the plain text in the requests/responses. I am new to the tool and Silverlight. Kindly help me with this issue.
