Loadrunner WebServices Error socket connection aborted

Question

I'm hitting a nettcp based WCF Service using LR VuGen 12.02 and Web Services protocol by importing the WSDL of the Service.

After composing a request and trying to send it, I'm getting the following error. which actually works fine from the WPF Client but fails from the LR VuGen Script

    Action.c(16): Error:The socket connection was aborted. This could be caused by an error processing your message or a receive timeout being exceeded by the remote host, or an underlying network resource issue. Local socket timeout was '00:59:59.9949990'. 
Error: An existing connection was forcibly closed by the remote host

I have tried out many suggestions relevant but with no luck For your reference: Increasing Timeouts and maxItemsInObjectGraph and many more such posts on StackOverflow such as Socket Connection Aborted-StackOverflow post

Any help is deeply appreciated.

Web Services will only work for HTTP binding, not NetTCP binding. For NetTCP binding the way to go is with a virtual user in Visual Studio. Use your client source to build a shell to pass your request. You will still have access to the parameterization engine and run time settings from inside of Visual Studio
