如何在linq中使用异步

public async Task<List<string>> GetNamesAsync()
{
    using (var context = new MyDbContext())
    {
        var names = await context.Users
            .Where(u => u.IsActive)
            .OrderBy(u => u.Name)
            .Select(u => u.Name)
            .ToListAsync();
        
        return names;
    }
}

using System.Data.Entity;
using System.Linq;
using System.Threading.Tasks;

public static class LinqExtensions
{
    public static async Task<List<T>> ToListAsync<T>(this IQueryable<T> query)
    {
        return await Task.Run(() => query.ToList());
    }
}
