Now when i converted from 4.3 to final 4.4 (build 7229) it broke my app in section where i using Mapper.Transform to convert real Entity object to mirror DTO object.

Method Mapper.Transform throws error The type Model.MyEntity hasn't been registered., but when i debug app then in quickwatch window variable of type MappingDescription passed to Mapper contains in property SourceTypes my entity Model.MyEntity and also in property TargetTypes contains my DTO type Model.MyEntityDto.

Stack trace (but i dont think its helpfull here):

   at Xtensive.ObjectMapping.Model.MappingDescription.ThrowTypeHasNotBeenRegistered(Type type)
   at Xtensive.ObjectMapping.GraphTransformer.RegisterEnumerable(Object source, Type sourceSystemType)
   at Xtensive.ObjectMapping.GraphTransformer.Transform(Object source)
   at Model.Logic.Repository.AsDto[TResultDto](EntityBase entity)

Please help, because this error breaks down my application!
