How to create EntitySet for all DBSet<> in DbContext dynamically?

var odataBuilder = new ODataConventionModelBuilder();

When using the AddEntitySet(), my endpoints fail with the error:
System.InvalidOperationException: 'The entity set 'foo' is based on type 'foo' that has no keys defined.'

var t = typeof(foo);
odataBuilder.AddEntitySet(t.Name, odataBuilder.AddEntityType(t));

I am using Ef Core with fluent api to set key and navigation attributes

    [Table(nameof(foo))]
    public partial class foo:
        IEntityTypeConfiguration<foo>
    {
        void IEntityTypeConfiguration<foo>.Configure(EntityTypeBuilder<foo> builder)
        {
            _ = builder.HasKey(x => x.RecKey);
            _ = builder.HasIndex(x => x.Name).IsUnique();
        }
    }

How can I dynamically configure each EntitySet for my DbContext? Explicitly defining each of the hundreds of DbSet<> in my DbContext is both time consuming and error prone.
