I have some linq entities that inherit something like this:
public abstract class EntityBase { public int Identifier { get; } }
public interface IDeviceEntity { int DeviceId { get; set; } }
public abstract class DeviceEntityBase : EntityBase, IDeviceEntity
{
public abstract int DeviceId { get; set; }
}
public partial class ActualLinqGeneratedEntity : DeviceEntityBase
{
}
In a generic method I am querying DeviceEnityBase derived entities with:
return unitOfWork.GetRepository<TEntity>().FindOne(x => x.DeviceId == evt.DeviceId);
where TEntity has a contraint that is it a DeviceEntityBase. This query is always failing with an InvalidOperationException with the message "Class member DeviceEntityBase.DeviceId is unmapped". Even if I add some mapping info in the abstract base class with
[Column(Storage = "_DeviceId", DbType = "Int", Name = "DeviceId", IsDbGenerated = false, UpdateCheck = UpdateCheck.Never)]
