Entity Framework 6 & TPH inheritance: Map properties with the same name to same column by default

Question

As of EF6 it is possible to do something like this when configuring Entity mappings using Table Per Hierarchy inheritance:

public class MyContext : DbContext 
{
    public DbSet<Device> Devices { get; set; }

    protected override void OnModelCreating(DbModelBuilder modelBuilder)
    {
        modelBuilder.Entity<ABatteryPoweredDevice>().Property(c => c.BatteryLevel).HasColumnName("BatteryLevel");
        modelBuilder.Entity<ADifferentBatteryPoweredDevice>().Property(c => c.BatteryLevel).HasColumnName("BatteryLevel");
    }
}

BatteryLevel is not part of the Device base class- it is a property of the derived classes implemented to fulfill an interface contract.

Is it possible to make this the default behavior as opposed to having to add a new mapping for each derived class?

Answer 1

Used Custom Code First Conventions, which are available from EF6 onwards, to sort this out:

    protected override void OnModelCreating(DbModelBuilder modelBuilder)
    {
        //your code before
        modelBuilder.Properties().Configure(prop => prop.HasColumnName(prop.ClrPropertyInfo.Name));
        //your code after
    }

This maps properties with the same name in different derived types to the same table column without explicit calls like those mentioned in the question.

Is there any way to configure this only for a table in EF6? I try to use Properties<Table>() and even create a derived class consisting of every columns in the DB table to use Properties<FullTable>(), but nothing works. Setting Properties() would affect all tables in the DB and I don't want that to override existing configuration. – Revealment
