Autohosted App throws exception while accessing Host Web

var spContext = SharePointContextProvider.Current.GetSharePointContext(Context);

using (var clientContext = spContext.CreateUserClientContextForSPHost(

            {   clientContext.Load(clientContext.Web, web => web.Title);
                clientContext.ExecuteQuery();
                Response.Write(clientContext.Web.Title);
            }           
        }

In the above code it  throws Microsoft.SharePoint.Client.PropertyOrFieldNotInitializedException exception for clientcontext object when executed. Has anyone seen this before and can help with pointers?

I am using O365 for publishing the app.

Thanks
