Foreign Key properly set but can't access the data through foreign key

Hello, It's my first post on this forum, hoping for a positive response. 

I am attaching the relevant code for you guys to dig out the issue.

.CSHTML File (I am using this syntax to display the data)

  
              @Html.DisplayFor(modelItem => item.Manufacturers.Manufacturer)  
            
            
              @Html.DisplayFor(modelItem => item.CA.CAName)  
            
ListDinghies Action in Controller

public async Task ListDinghies()  
        {  
            return View(await _context2.Dinghies.ToListAsync());  
        }  
AddDinghies Post Action in Controller

public async Task AddDinghies([Bind("id,Name,OlympicBoat,Type,TypeCrew,TypePurpose,Length,Beam,Draft,SailAreaUpwind,GennakerSailArea,SpinnakerSailArea,SAOptional,SAOptional2,Weight,PYS,ImagePath,CrewPersons,CrewWeight,Description,DesignBy,DesignYear,OlympicSectionViewSwitch,ManufacturerID,ClassAssociationID")] Dinghies dg)  
        {  
            if (ModelState.IsValid)  
            {  
               //_context2.Manufacturers.Include(e => e.Manufacturer).FirstOrDefault(m => m.id == );  
                _context2.Add(dg);  
                await _context2.SaveChangesAsync();  
                return RedirectToAction(nameof(Index));  
            }  
            return View(dg);  
        }  
Dinghies.cs (Only showing section where foreign keys and navigation properties are added)

[ForeignKey("Manufacturers")]  
        public int ManufacturerID { get; set; }  
        public Manufacturers Manufacturers { get; set; }  
  
        [ForeignKey("CA")]  
        public int ClassAssociationID { get; set; }  
        public CA CA { get; set; }

        [DisplayName("Country: ")]  
        public string Country { get; set; }  
  
        [Column(TypeName = "nvarchar(50)")]  
        [DisplayName("Telephone: ")]  
        public string Telephone { get; set; }  
    }  
}  

I have searched a lot on internet but couldn't find the solution, I believe only an expert can figure out the problem. Thanks
