Sharepoint in ax 2009. Several questions

Hello,

I am using Sharepoint int AX 2009.

1. Need to refer to a new function on AX, so I add this reference in web -> web files -> static files -> proxies, but in VS 2008, I didn't realized where is axSession interface (and any helper) that I have some predefined codes to put in.

2. For some reasons, several configurations are not compiled due some reference of code : Microsoft.Dynamics.Framework.BusinessConnector.Adapter, so I think I should add some reference in web.config - How can I do that?

Thanks :)
