How would I write the following C# code in F#?

namespace Shared {
    public class SharedRegistry : PageRegistry {
        public SharedRegistry(bool useCache = true)
            : base(useCache) {
            // Repositories
            ForRequestedType<IAddressRepository>().TheDefaultIsConcreteType<SqlAddressRepository>();
            ForRequestedType<ISharedEnquiryRepository>().TheDefaultIsConcreteType<SharedEnquiryRepository>();

            // Services
            ForRequestedType<IAddressService>().TheDefaultIsConcreteType<AddressService>();
            ForRequestedType<ISharedEnquiryService>().TheDefaultIsConcreteType<SharedEnquiryService>();
        }
    }
}

As is as far as I have managed, but I can't work out to inherit from PageRegistry at the same time as declaring my own default constructor.

type SharedRegistry(useCache: bool) =
    inherit PageRegistry(useCache)
    new() = new SharedRegistry(true)
