How to: Add or Remove SharePoint Connections
Server Explorer lets you browse SharePoint sites as well as data connections. However, before you can browse the contents of a SharePoint site you must add it to the SharePoint Connections node.
To add a SharePoint site to the SharePoint Connections node
Open Server Explorer by clicking Server Explorer on the View menu.
Right-click SharePoint Connections and then click Add Connection.
In the Add SharePoint Connection box, enter the URL for the SharePoint site. For example, http://testserver/sites/unittests.
To delete a SharePoint site from the SharePoint Connections node
Open Server Explorer by clicking Server Explorer on the View menu.
Expand the SharePoint Connections node to reveal the SharePoint site that you want to delete from SharePoint Server Explorer.
Right-click the site and then click Delete.
Note
This does not delete the underlying site, it only deletes the connection from Server Explorer.
