Code First Entity Framework pointless queries
===

I am using Code First on a site and a number of queries that are being run are pretty pointless as they don't return anything.

Running EF 4.3.1

Its unclear why this happens but it adds unnecessary calls to the DB?

    SELECT 
    [GroupBy1].[A1] AS [C1]
    FROM ( SELECT 
            COUNT(1) AS [A1]
            FROM [dbo].[MyDataTable] AS [Extent1]
    )  AS [GroupBy1]   

does anyone have any idea or how to stop them??
