The entity type EntityBase is not part of the model for the current context

I am using EF 6 and have following

public class Title : EntityBase
{

    public short Id { get; set; }
    public string TitleName { get; private set; }

}
 public abstract class EntityBase
{
    public DateTime CreatedDate { get; set; }

}

And DbContext contains

public DbSet<Title> Titles { get; set; }

and also 

modelBuilder.Entity<Title>().Map(m =>
       {
           m.MapInheritedProperties();
           m.ToTable("Titles");
       });

But while trying to access Titles, I get "The entity type EntityBase is not part of the model for the current context." After I run Update-Database in NuGet console, I see that table 'Titles' is created in database with all fields (id,titlename, createddate) as expected. I don't want to add EntityBase db set in DbContext if possible. Kindly help me to find a solution.

MapInheritedProperties is used to model a table-per-concrete type (TPC) mapping, a complete table for each class. You can do this, but then you have to configure the base class as well.

modelBuilder.Entity<EntityBase>();

However, I'd rather remove the MapInheritedProperties statement and map each class individually. If you map a TPC mapping you'll never be able to map other inheritance associations between other classes of your model.
