如何访问引用其他对象的 AppUser 属性？ （ASP.NET/EFCore）

Question

I have an AppUser class that inherits from IdentityUser and contains an Inventory object:

public class AppUser : IdentityUser
    {
        public InventoryModel? Inventory { get; set; }
    }

I've been using this line to get the current user with all their properties:

var user = await _userManager.GetUserAsync(User);

Any primitive data types I put in AppUser can be accessed this way, but it seems to be lazy loading and not bringing the inventory along with it. I have manually queried my database and I see that the user I'm getting has an Inventory.InventoryId of 14 (primary key identifier for the Inventory class), but when I use the above statement to get the user, their Inventory is always null.

Is there some kind of ".Include()" that can be used with GetUserAsync? Is there another way I should be doing this?

For anyone with this same issue looking for a quick fix:

As Eldar suggested, I injected the ApplicationDbContext and then did something like this:

//get lazy-loaded current user using the usermanager

var lazyUser = await _userManager.GetUserAsync(User);


//get current user with includes using the ApplicationDbContext
//and the Id from the current user I already grabbed

var user = await _context.AppUsers.Where(u => u.Id == lazyUser.Id)
                                  .Include(u => u.Inventory)
                                  .SingleOrDefaultAsync();

It's pretty inelegant but technically it accomplish what I wanted to accomplish.
