This answer will not solve your problem directly, but first of all I recommend you to outsource the filling of the ViewModel at least to the controller (Because otherwise it will recreate the DBContext every time the constructor is called). A ViewModel should only contain data - no logic. And secoundly I would use the DBContext in an Using statement

ViewModel:

public class LookUpViewModel
    {    
        [Required]
        public virtual IEnumerable tblCurrentLocations { get; set; }

        [Required]
        public virtual IEnumerable tblStreams {  get;  set; }

Controller:

public ActionResult Foo()
{
    LookUpViewModel ViewModel = new LookUpViewModel();
    using(RosterManagementEntities rosterManagementContext = new RosterManagementEntities())
    {
        ViewModel.tblCurrentLocations = from o in rosterManagementContext.tblCurrentLocations select o;
        ViewModel.tblStreams = from o in rosterManagementContext.tblStreams select o; 
    }

    return View(ViewModel);
}
