使用对象作为关键字时.Net MemoryCache未命中

var cacheKey = myObject.Id.ToString(); // 使用 ID 作为键

public class MyObject
{
    public int Id { get; set; }
    public string Name { get; set; }

    public override bool Equals(object obj)
    {
        if (obj is MyObject other)
        {
            return Id == other.Id && Name == other.Name;
        }
        return false;
    }

    public override int GetHashCode()
    {
        return HashCode.Combine(Id, Name);
    }
}

var cacheItemPolicy = new CacheItemPolicy
{
    AbsoluteExpiration = DateTimeOffset.Now.AddMinutes(10) // 10分钟后过期
};

memoryCache.Set(cacheKey, myObject, cacheItemPolicy);

using System;
using System.Runtime.Caching;

public class Program
