EntitySqlException on select with code first dbcontext in Entity Framework

Question

When

var codeFirstRepositor = new Donors();
var list = codeFirstRepositor.CampaignReps.Select(c => c).ToList();

• When I put a breakpoint inside the CampaignRep class constructor it is not called at all - the exception seems to occur before object instantiation

Context

public class Donors : DbContext
{
    public Donors()
    {
        // Needed for WCF serialization to work
        Configuration.ProxyCreationEnabled = false;
    }
    public DbSet<CampaignRep> CampaignReps { get; set; }
}

EntitySqlException

'CampaignsReps' is not a member of Transient.collection[MyNameSpace.Donor(Nullable=True,DefaultValue=)]'. To extract a property of a collection element, use a subquery to iterate over the collection. Near escaped identifier, line 1, column 10.

What is the cause of this error?

Answer 1

Remove the Select(c => c) and try again. Also, why do you even have that in your query?
