Inconsistent accessibility: property type in class is less accessible than property type in Interface

Not sure what's wrong here but I am trying to use an enum in an interface I've created.

When I attempt to implement the interface I get the error

Inconsistent accessibility: property type 'System.Collections.Generic.IList' is less accessible than property 'BusinessEntities.ICloneMessage.AgentAddresses'

Enum

namespace BusinessEntities
{
    public class AddressTypeValues
    {
        [DataContract(Name = "AddressType")]
        public enum AddressType
        {
            [EnumMember(Value = "Home")]
            Home,
            [EnumMember(Value = "Mailing")]
            Mailing,
            [EnumMember(Value = "Location")]
            Location,
            [EnumMember(Value = "Other")]
            Other
        }
    }
}

Interface

namespace BusinessEntities
{
    public interface IAgentAddress
    {
        AddressTypeValues.AddressType AddressType { get; set; }
        String? Street1 { get; set; }
        String? Street2 { get; set; }
        String? Street3 { get; set; }
        String? City { get; set; }
        String? State { get; set; }
        String? ZipCode { get; set; }
    }
}

Classes using AddresType

namespace BusinessEntities
{
    [DataContract]
    public class CloneMessage : ICloneMessage
    {
        [DataMember]
        public AgentTransmission AgentInformation { get; set; }
        [DataMember]
        public IList<AgentAddress> AgentAddresses { get; set; }
        [DataMember]
        public IList<RelationshipCode> RelationshipCodes { get; set; }
        [DataMember]
        public string? ErrorMessages { get; set; }
        public CloneMessage(){}
    }
}
namespace BusinessEntities
{
    [DataContract]
    public class AgentAddress : IAgentAddress
    {
        [DataMember]
        public AddressTypeValues.AddressType AddressType { get; set; }
        [DataMember]
        public string Street1 { get; set; }
        [DataMember]
        public string Street2 { get; set; }
        [DataMember]
        public string Street3 { get; set; }
        [DataMember]
        public string City { get; set; }
        [DataMember]
        public string State { get; set; }
        [DataMember]
        public string ZipCode { get; set; }
    }
}

There are couple of errors in your code.

First. Your class AgentAddress is not marked as public. That is why you are getting the error. Probably your class is not defined with any access specifier and it is considered as internal. Making your class public would remove the error.

Second problem in your code is that you are using String?. May be trying to make string as Nullable<T>. String is already a reference type, it can hold null. You need to remove ? with String?. So your interface would look like:

public interface IAgentAddress
{
    AddressTypeValues.AddressType AddressType { get; set; }
    String Street1 { get; set; }
    String Street2 { get; set; }
    String Street3 { get; set; }
    String City { get; set; }
    String State { get; set; }
    String ZipCode { get; set; }
}

Nullable<T> or type with ? is used for value types, since value types can't hold null like int? or Nullable<int>
