How to load navigation properties on an IdentityUser with UserManager

Question

I\'ve extended IdentityUser to include a navigation property for the user\'s address, however when getting the user with UserManager.FindByEmailAsync

Answer 1

Unfortunately, you have to either do it manually or create your own IUserStore where you load related data in the FindByEmailAsync method:

public class MyStore : IUserStore, // the rest of the interfaces
{
    // ... implement the dozens of methods
    public async Task FindByEmailAsync(string normalizedEmail, CancellationToken token)
    {
        return await context.Users
            .Include(x => x.Address)
            .SingleAsync(x => x.Email == normalizedEmail);
    }
}

Of course, implementing the entire store just for this isn't the best option.

You can also query the store directly, though:

UserManager userManager; // DI injected

var user = await userManager.Users
    .Include(x => x.Address)
    .SingleAsync(x => x.NormalizedEmail == email);
