One of our application(Thick client ,Client Server application) is developed in .NET Framework that uses WCF service-oriented architecture (including components developed in C# and VB.NET).I would like to know whether load runner can be used for conducting performance test for this application
Try the Web Services or Service Test vuser type if you have access to a WSDL. If you do not have access to HP Service Test, you can still build a web services script in Vugen, either using a WSDL or by recording the client application.
Of course the best way to find out is to download the trial and give it a shot. If you are unfamiliar with LoadRunner, you can try using the Protocol Advisor in the File menu under Virtual User Generator (Vugen). The trial can be downloaded at www.hp.com/go/loadrunner
I actually had a conversation with a guy that had this very same issue. I didn't know about WCF but doing a little research on it and LR11, it should be supported with the SOA protocol. Using the Protocol Advisor should let you gain insight to what LR can capture. I believe you can even script a scenario using the VuGen without having a license for the protocol. However, you will only be able to use it in a single user situation as the controller will need to be licensed to drive load with the script.
