Twilio Rest API 引发错误：无法从程序集"Twilio，版本=1.0.0.0，区域性=中性，公钥令牌=空"加载类型"Twilio.TwilioClient"

Question

这是我在 C# ASP.Net Mvc 项目中运行的代码。 引发的错误标识它是在闭大括号 (}( 处抛出的。

public ActionResult SendSms()
{
const string accountSid = "ACCOUNT_SID";
const string authToken = "AUTH_TOKEN"; 
TwilioClient.Init(accountSid, authToken);
var to = new PhoneNumber("+NUMBER");
var from = new PhoneNumber("+NUMBER");
var message = MessageResource.Create(
to: to,
from: from,
body: "This is a test.");
return Content(message.Sid);
}

我也尝试过使用

TwilioRestClient restClient = new TwilioRestClient(accountSid, authToken);

代替 TwilioClient.Init(...(; 命令。 会产生相同的错误。 下面是错误和堆栈跟踪：

我做错了什么？ 我使用的是 Twilio 版本 5.13.4、VS 2017 和 Windows 8。 我也完全看不到消息是如何发送的，TwilioClient 是否只是寻找一个 MessageResource 对象并发送它？ 也许我对此的误解是它不起作用的原因，但我准确地遵循了本教程 https://www.youtube.com/watch?v=ndxQXnoDIj8(我假设(并且仍然会产生错误。 直接从 Twilio 站点的不同 c# 实现会产生相同的错误。

更新：我注意到视频中Twilio的版本号是5.3.0，并回溯到该版本号，但发生了相同的错误。

一个潜在的原因是，如果你把你的项目命名为"Twilio"。
