Does LR 12 support net tcp protocol

Hi, 

The product in my company is using nettcp binding. I failed to let VUGen to record actions that were performed on the product. (I have no idea which protocol i should select, i have tried .net, Winsock, but neither of them is working)

I read from http://softwaretesttips.com/2011/04/20/about-silverlight-protocol-and-versions-suppported-with-loadrunner-11/ that LR 11 does not support net tcp protocol.

Does anyone know that if LR 12 support nettcp protocol or not?

Thanks in advance

Cheers.

Kai
