IncludeMembers Inheritance

[NismanSolutions]

I am trying to reuse the base map that has both ForMember explicit mapping and IncludeMembers for a nested object in the derived classes using IncludeBase. This always results in an error: 'Property [baseProperty] is not defined for type [nestedType]'.

Here is the code:

https://gist.github.com/NismanSolutions/e7a73fe1c295d2c80fa115c85295aabd

class GroupUser
{
int userId;
ApplicationUser User;
}

class ApplicationUser
{
}

class UserDto
{
int id;
}

class User2Dto : UserDto
{
}

CreateMap<GroupUser, UserDto>()
.IncludeMembers(src => src.User)
.ForMember(dest => dest.id, memb => memb.MapFrom(src => src.userId)); // This causes the error in the derived mapping

CreateMap<GroupUser, User2Dto>()
.IncludeBase<GroupUser, UserDto>();

Error: "Property 'userId' is not defined for type 'ApplicationUser'"

Why is it trying to use userId on nested type ApplicationUser? I'd expect that this should maintain the relation of the userId mapping with the original source type: GroupUser where the userId is defined. Am I missing something or this is a bug?

Thank you.
