I just installed the SharePoint SDK on my machine, but I can’t seem to find the location of Microsoft.Sharepoint.dll so I can add a reference to it.
It’s not in the GAC or C:\Program Files\Common Files\Microsoft Shared\Web Server Extensions\12\ISAPI\ and a search comes up with nothing.
Any suggestions?
The dll is on the server where you installed SharePoint. You should not develop on a desktop machine, create a virtual machine with SharePointserver installed and work there. See: http://weblogs.asp.net/erobillard/archive/2007/02/23/build-a-sharepoint-development-machine.aspx
