Support top level Json Arrays for JsonColumns in EF

[AlexanderBaggett]

I'm trying to store an array of json data in a column in EF

I'd like to have support for top-level Json Arrays for JsonColumns in EFCore.
Right now I have to create an empty wrapper class whose only job is to have a collection property and make that my JsonColumn via OwnsOne() and ToJson().

I'd like to be able to do OwnsMany() and ToJson() on a property which is a List and it just works.

E.g. I'd like to be able to do this:

    public class SomeEntity
    {
        public List<SomeOtherClass> Values = new List<SomeOtherClass>();
    }
    public class SomeEntity_Map : IEntityTypeConfiguration<SomeEntity>
    {
        public void Configure(EntityTypeBuilder<SomeEntity> builder)
        {
            builder.OwnsMany(x => x.Values,x =>  x.ToJson());
        }
    }
