在EntityframeworkCore中使用异步/等待的最佳方式

using Microsoft.EntityFrameworkCore;
using System.Collections.Generic;
using System.Linq;
using System.Threading.Tasks;

public class MyDbContext : DbContext
{
    public DbSet<User> Users { get; set; }

    public async Task<List<User>> GetUsersAsync()
    {
        return await Users.ToListAsync();
    }
}

using Microsoft.EntityFrameworkCore;
using System.Threading.Tasks;

public class MyDbContext : DbContext
{
    public DbSet<User> Users { get; set; }

    public async Task SaveUserAsync(User user)
    {
        Users.Add(user);
        await SaveChangesAsync();
    }
}

using Microsoft.EntityFrameworkCore;
using System.Collections.Generic;
using System.Threading.Tasks;

public class MyDbContext : DbContext
{
    public DbSet<User> Users { get; set; }

    public async Task DeleteUsersAsync(List<User> users)
    {
        Users.RemoveRange(users);
        await SaveChangesAsync();
    }
}
