Add Service Reference is generating Message Contracts

like below fixes the issue When I import a given service using "Add service Reference" on Visual Studio 2008 (SP1) all the Request/Response messages are being unnecessarily wrapped into Message Contracts (named as --> "operationName" + "Request"/"Response" + "1" at the end). , I had this same issue and this solved it.
I used this:

Can add one Service Reference for multiple WCF Service Contracts

I wish did fix the issue. As it stands, I don't think this is possible, you will need 2 service references as they both implement seperate contracts. Assuming you have control of the service code, you could implement a workaround where you create a service wrapper to implements both the contracts by pointing to the two seperate services. That would allow you to have one service reference. Is there a particular issue as to why you want them both in one service as opposed to two?
EDIT: This Blog Article - Meineck.Net shows you how you can configure your services to achieve what you're after, but again it's pretty much a work around. Good luck.

To fix this issue You can't control the code in the generated proxy. If you want, you can do the proxy generation yourself, using the MetadataExchangeClient / ServiceContractGenerator classes. They'll give you a CodeDom object containing the code which you can modify (i.e., change fields into properties). There's an example of using the MEC/SCG classes in the MSDN forum post at http://social.msdn.microsoft.com/Forums/en-US/wcf/thread/14100bbb-9a73-4bcc-b513-088bb2e5ec65.

will be helpful for those in need Ok, I was finally able to solve it. All I had to do was clean the solution. Right-click on the topmost solution node in the Solution Explorer, and choose "Clean Solution". After that, I did a "Rebuild All" on the service project. Finally, I did an "Update Service Reference" on the service reference in my client application, and it then updated correctly with all my types. Still not sure what happened, but at least this cleared out whatever gremlins were messing things up.

With these it helps
When I use Visual Studio to create a WCF client ("Add Service Reference") and I click on "Advanced...", the checkbox which says "Always generate message contracts" does properly control whether the message contract objects are generated.

I wish did fix the issue. I am far from an authority on these issues, and while this response below might not be an exact fit to your problem, my recent experience of making a proxyless connection to a service might offer some insight to you or the next person with a similar issue.
I would start by seeing if you can hand roll the SOAP request using fiddler, and see if you are able to create the correct message and send that along. Since you describe the automation tools as being buggy (or perhaps there is a config issue you're not getting just so). Either way, having a clear understanding of the shape of the contract, and being able to perform a reliable test in fiddler may offer clarity.
