AX 2012 web service question

I created a web service in AX. I added a few methods. If I change the code in any of these methods and then redeploy the service group and in VS 2010 if I right-click on the service reference and click Update", then the changes are available in my .Net project.

But if I add a new method to my class in AX and then follow the above steps, I do not see the new method in VS 2010. So how do I add a new method to my web service and then get it to show up in my VS 2010 web site project?

Sorry, posted this twice by mistake.

Can you deactivate and activate the inbound port?
