It is hard for me to tell if that is the same issue or not, at this point. Could you, please, share a bit more details to help me understand what is the exact scenario and behavior? You can use the following topics as guidelines to share additional information.
- Is the Silverlight application out of browser? If that is the case, you will not be able to combine it with a web test out of the box.
- In case it is a browser based Silverlight application, I would like to know, where are the asp pages loaded? Do you see a new instance of the browser or a completely different browser open with that content? If it is a new instance of a browser, it is expected that Test Studio is not able to recognize it and continue recording and executing the test steps.
- I will appreciate, if you can share more details and a sample runnable test that I can try on my end. This way I can check the behavior and investigate the scenario further.
I am looking forward to hearing from you.
