Ignoring properties in an owned type using fluent API

[coder925]

How should one ignore properties in an owned type using fluent call? I have figured out how to do this with attributes by adding [NotMapped] to the property, but not how the same is done using Fluent API.

In EF 6 I was able to ignore properties on a complex type like this:
modelBuilder.ComplexType<StreetAddress>().Ignore(a => a.City);

In EF Core 2.2, it is possible to define the type but not continue with Ignore:
modelBuilder.Owned<StreetAddress>();

The by-design restrictions tell me I cannot do this:
modelBuilder.Entity<StreetAddress>().Ignore(a => a.City);

I think it would be helpful with a section in the documentation of Owned Entity Types about ignoring properties in an owned type using both attributes and fluent API.

Currently it's only possible to do for a specific reference.

modelBuilder.Entity<Order>().OwnsOne(
    o => o.ShippingAddress,
    sa =>
    {
        sa.Ignore(p => p.City);
    });
