Not Projecting EF table-per-hierarchy (TPH) inheritance correctly

[Tinus-H]

Hello Yuriy

I'm having some trouble using the .Project<,> with an EF table-per-hierarchy (TPH) inheritance

I have an Inherited EF Entity with 3 other Entities Inheriting from it.
I'm then trying to Project those Entities to Dtos

Please have a look at the code link below for the full project
https://github.com/Tinus-H/TestDbExample

The problem is as follow

I have these Entities

    public class InheritedSharedEntity : SharedEntity, IInheritedSharedEntity
    {
        public string GroupType { get; set; }
    }

    public class InheritedStringEntity : InheritedSharedEntity, IInheritedStringEntity
    {
        public string StringValue { get; set; }
    }

    public class InheritedIntEntity : InheritedSharedEntity, IInheritedIntEntity
    {
        public int IntValue { get; set; }
    }

    public class InheritedBoolEntity : InheritedSharedEntity, IInheritedBoolEntity
    {
        public bool BoolValue { get; set; }
    }

and I want to Project them to these Dtos

public class InheritedSharedEntityDto : SharedEntityDto, IInheritedSharedEntity
    {
        public string GroupType { get; set; }
    }

    public class InheritedStringEntityDto : InheritedSharedEntityDto, IInheritedStringEntity
    {
        public string StringValue { get; set; }
    }

    public class InheritedIntEntityDto : InheritedSharedEntityDto, IInheritedIntEntity
    {
        public int IntValue { get; set; }
    }

    public class InheritedBoolEntityDto : InheritedSharedEntityDto, IInheritedBoolEntity
    {
        public bool BoolValue { get; set; }
    }

I registered it as follow

        Mapper.Register<InheritedSharedEntity, InheritedSharedEntityDto>()
                .Include<InheritedStringEntity, InheritedStringEntityDto>()
                .Include<InheritedIntEntity, InheritedIntEntityDto>()
                .Include<InheritedBoolEntity, InheritedBoolEntityDto>();

But this does Not Work, it only returns a list of InheritedSharedEntityDto the Base Class

        public IHttpActionResult GetProjectDtos()
        {
            return Ok(_context.InheritedSharedEntities.AsNoTracking()
                .Project<InheritedSharedEntity, InheritedSharedEntityDto>());
        }

But this does Work and return a list of the Derived Classes

        public IHttpActionResult GetMapDtos()
        {
            return Ok(_context.InheritedSharedEntities.AsNoTracking()
                .Map<IEnumerable<InheritedSharedEntity>, IEnumerable<InheritedSharedEntityDto>>());
        }

Because we are using jsonFormatter.SerializerSettings.TypeNameHandling = TypeNameHandling.All; we are able to Deserialize the JSON back into the correct Derived Dto Classes client side, we would like to use the .Project<,> because most of our Web API GET calls are OData calls and support paging and the `Map<IEnumerable<>,IEnumerable<>>' queries the whole DB and then only returns the page size results.

Could you please help, I don't know if I'm doing something wrong or if it is even possible.
