Answer 1

What worked for me is using : LifeStyle BoundTo

    container.Register(Component.For()
            .ImplementedBy()
            .LifeStyle.BoundTo());

Graph :

     public class ViewModelAConductor 
     {
         private List rootViewModels = new List();
         public ViewModelAConductor()
         {
              ViewModelA a1 = container.Resolvce(); 
              rootViewModels.Add(a1);

              ViewModelA a2 = container.Resolvce(); 
              rootViewModels.Add(a2); 
         }
     }

     public class ViewModelA
     {
          ViewModelB viewModelB;
          IService service;

          public ViewModelA(IService service,ViewModelB viewModelB) 
          {
              this.service = service;
              this.viewModelB = viewModelB;
          }               
     }

     public class ViewModelB
     {
          ViewModelC viewModelC;
          IService service;

          public ViewModelA(IService service,ViewModelC viewModelC) 
          {
              this.service = service;
              this.viewModelC = viewModelC;
          }               
     }  

     public class ViewModelC
     {
          IService service;

          public ViewModelA(IService service) 
          {
              this.service = service;                 
          }               
     }  

All ViewModels injected under the Graph of a1 have the same instance of IService.

All ViewModels injected under the Graph of a2 have the same instance of IService.
