Inheritance hierarchies that include owned entity types are not supported #14451

@sbsw This means that owned entity types cannot themselves be in an inheritance hierarchy. It does not mean that entity types that are part of an inheritance hierarchy cannot have owned types. For example, this is fine: public class Blog
{
public int Id { get; set; }
}
public class GoodBlog : Blog
{
public Address HomeAddress { get; set; }
public Address WorkAddress { get; set; }
}
public class Address
{
public string Street { get; set; }
public string Zip { get; set; }
}protected override void OnModelCreating(ModelBuilder modelBuilder)
{
modelBuilder.Entity<Blog>();
modelBuilder.Entity<GoodBlog>(b =>
{
b.OwnsOne(e => e.HomeAddress);
b.OwnsOne(e => e.WorkAddress);
});
}For the not supported case, see #9630 |

Oh. In that case, I seem to have stumbled across a bug. I’ll see if I can re-create the issue in a simple example, and open a new issue on that.
I will also put in a documentation issue to clarify the inheritance limitation.

Sorry if I'm commenting on this closed issue in error, but I seem to be having the following related issue to inheritance and owned entity types. Given the following: [Owned]
public class FileGuid
{
public Guid Guid { get; set; }
public string FileExtension { get; set; }
}
public abstract class Asset
{
public Guid Guid { get; set; }
public string Name { get; set; }
}
public class MaterialAsset : Asset
{
public int Color { get; set; }
public bool Transparent { get; set; }
public float Opacity { get; set; }
public FileGuid TextureAsset { get; set; }
public FileGuid DecalTextureAsset { get; set; }
}
protected override void OnModelCreating(ModelBuilder modelBuilder)
{
modelBuilder.Entity<Asset>().HasKey(a => a.Guid);
modelBuilder.Entity<MaterialAsset>().HasBaseType<Asset>();
modelBuilder.Entity<MaterialAsset>().OwnsOne(ma => ma.TextureAsset, o =>
{
o.Property(fg => fg.Guid).HasColumnName("TextureAsset_Guid");
o.Property(fg => fg.FileExtension).HasColumnName("TextureAsset_FileExtension");
});
modelBuilder.Entity<MaterialAsset>().OwnsOne(ma => ma.DecalTextureAsset, o =>
{
o.Property(fg => fg.Guid).HasColumnName("DecalTextureAsset_Guid");
o.Property(fg => fg.FileExtension).HasColumnName("DecalTextureAsset_FileExtension");
});

The documentation states:
The practical upshot of this is that any class that inherits from
IdentityUsercannot reliably include an owned type. This is turning out to be a major headache.So, I have two questions:
