I am trying to access Share point portal server through console
application and i am geting error..

File or assembly name Microsoft.SharePoint.Library, or one of its
dependencies, was not found.

I am trying only one line of code ie.

SPSite siteCollection = new SPSite
("http://rac866/sites/TeamSite/default.aspx");

I have copied the Microsoft.SharePoint dll from server to my
development PC and have tried by putting into Gac too.
