Entity Framework - Cannot convert lambda expression to type 'string' because it is not a delegate type

Question

I am using Entity Framework in my C# based code. I am running into an unexpected weirdness and am looking for suggestions.

Case 1, 2, 3, 4... Projects:
RivWorks

Answer 1

In my case I had this error when trying to use Include in clientContext.Load in a Sharepoint 2013 app.

I had included Sharepoint client library like so:

using SP = Microsoft.SharePoint.Client;

To fix, in addition I also added it without the namespacing:

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