  Hello to all, I downloaded T4 Dto Template from Code Library. I modified the template to suit my need, but somenthing draw my attention. From what I see in the Dto objects only the 1:many relationship is mapped, the many:1 isn't.
  
  Why is this done? How does Telerik recommends creating Dto object using the template from code library or there is another way?
  Thanks in advance,
  LordRevan007

  Hello LordRevan007,
  
  This DTO template generates only the "collection" part of 1:N associations. For M:N associations, only one of the association ends is generated, which is a collection as well. If the second end was generated in parallel, this would easily lead to errors because of cyclic references during serialization of the object graph. And this is actually the main reason for generating the code this way.
  Hope that helps.
