I've got a class that is derived from a simple base class.

public class A
{
public string Id { get; set; }
public long Value { get; set; }
}

public class B: A {}

I build the mapping for B like this

...
builder.Entity<B>().Property(p => p.Id)....
builder.Entity<B>().Property(p => p.Value)....
...

I get the following error when I call DataContext.CreateDatabase(false, true)
"Table 'B' has no columns."

The same steps work if I replace 'B' with 'A' in the table definition and in the fluent-specific code.

Question: How can I map the public properties of a base class as columns?

Thanks for the links. I missed the inheritance part of the documentation. TPH should provide and adequate solution for my problem.
