System.Object being discovered as EntityType through navigation.

I tried today to update my solution to RC1 from beta8 and get the exception The derived type 'FieldDefinitionEntity' cannot have keys other than those declared on the root type.. The root type is not mapped, only the derivied type. Should the mapping throw this exception anyway?

public class FieldDefinitionEntity : FieldDefinitionEntityBase
{
    public virtual bool MultiCulture { get; set; }
}

public abstract class FieldDefinitionEntityBase
{
    public virtual string FieldType { get; set; }
    public virtual string Id { get; set; }
}

Mapping

builder.Entity<FieldDefinitionEntity>(b =>
{
    b.ToTable("FieldDefinition", "Products");
    b.HasKey(p => p.Id);
});

@markolbert RC2 hasn’t shipped the closest we have is staged in this NuGet feed: https://www.myget.org/F/aspnetrelease/api/v3/index.json

(More information about the different feeds at https://github.com/aspnet/Home/wiki/NuGet-feeds)

I don’t think we have any comprehensive guidance on how to move an existing RC1 project to RC2 yet.

Diego, I’m using 7.0.0-rc1-final (the “stock” configuration that comes up when you create a new ASPNET5 web project in VS2015). I’m open to trying something more recent. What’s the easiest way to do that?
