c# proxies var keyword

this doubt associated before post cave . basically, i wish inject dao an entity i.e.

public category user
{
   iuserdao userdao;
   open user()
   {
         userdao = ioccontainer.resolve<iuserdao>;
   }
  open user(iuserdao userdao)
   {
         this.userdao = userdao;
   }
   //wrapped dao methods i.e
   open user save()
   {
       relapse userdao.save(this);
   }

}

here i tradition methods dao following i fundamentally have hang entity object. i iuserdao.register() i following have emanate user.register() slight hang it.

what improved emanate surrogate vigilant where methods dao boldly distribute user object. i competence have something looks this:

var user = daoproxyservice.create(new user());
user.save();

this meant i keep user entity graceful reticent category suitable information send over wire, nonetheless also magically give garland dao methods.

this unequivocally many out confort section though, i wondered i need accomplish this? i castles enterprising proxy? also c# compiler means cope know boldly total methods?

feel giveaway let me know nonsense.

edit:

what need somehow announce daoproxyservice.create() returning user vigilant -- during accumulate time. finished generics.

this isnt definitely true, i wish relapse isn't user vigilant nonetheless user vigilant boldly total userdao methods. category isn't defnied anywhere compiler know it.

what i am radically returning new vigilant looks like: user : iuserdao, i speculation i ban required. nonetheless seems messy.

looks i am looking identical this:
