Question

I’m trying to test this code snippet but I get the “Missing a using directive or an assembly reference” error on “ClientContext oContext = new ClientContext(siteUrl);” I’m copying and pasting directly from the Microsoft site so I’m not sure what am I missing…

using System;
using Microsoft.SharePoint.Client;
using SP = Microsoft.SharePoint.Client;

namespace Microsoft.SDK.SharePointServices.Samples
{
    class BreakSecurityInheritance
    {
        static void Main()
        {
            string siteUrl = "http://MyServer/sites/MySiteCollection";
            ClientContext oContext = new ClientContext(siteUrl);
            SP.List oList = oContext.Web.Lists.GetByTitle("Announcements");

            oList.BreakRoleInheritance(true, false);

           oContext.ExecuteQuery();
        }
    }
}

As said earlier, you need a reference to the SharePoint client object model. Luckily, you can get those from Microsoft as part of the SP Client OM redistributable without having to install a full local SharePoint server.
