如何使FluentAssertions shouldbeequivalent当比较时检查类型

我有两个字典，我希望内容不相等，因为字典包含不同类型的值。但是下面的测试通过了

[Scenario]
public void DictionariesWithDifferentTypesShouldBeEquivalent(
    Dictionary<string, object> firstDictionary, 
    Dictionary<string, object> secondDictionary)
{
    "Given a dictionary"
        .f(() => firstDictionary = new Dictionary<string, object> 
                    {
                        { "latency", 0 },
                        { "errorMessages", new string[0] },
                        { "lastChanged", new DateTime(635272310930829706) },
                        { "query", new string[0] },
                        { "items", new string[] { "foo", "bar" } },
                        { "name", "Bob" },
                        { "number", 3 },
                        { "updateInterval", 10 },
                    });
    "And a second dictionary with same values but of differing types"
        .f(() => secondDictionary = new Dictionary<string, object> 
                    {
                        { "latency", 0L },
                        { "errorMessages", new object[0] },
                        { "lastChanged", new DateTime(635272310930829706) },
                        { "query", new string[0] },
                        { "items", new string[] { "bar", "foo" } },
                        { "name", "Bob" },
                        { "number", 3 },
                        { "updateInterval", "10" },
                    });
    "When I check for equivalency"
        .f(() => { });
    "Then the dictionaries should be equivalent"
        .f(() => firstDictionary.ShouldBeEquivalentTo(secondDictionary));
}

如果这是预期的行为，我如何设置一个流畅的断言规则来检查类型匹配?

我已经研究了使用MatchingRule和AssertionRule，但在这两种情况下，我似乎都无法访问主题和预期的原始类型。看起来主题已经被转换成预期的类型。例如，在上面的示例中，第一个字典中的updateInterval应该已经被转换为字符串，以便与第二个字典进行比较。

谢谢你的帮助，
