InvalidOperationException：记录读取器索引不同步

Question

我有使用 mongodb 作为后端的 asp.net 核心应用程序。

最近，我开始收到此错误，而数据库或代码没有任何更改。

这是我浏览 API 时遇到的完整错误

An error occurred while starting the application.

事实证明，该问题与连接字符串和我的驱动程序版本有关。

C# MongoDB 驱动程序依赖于DNSClient.Net 包，它用于对连接字符串进行 DNS 查找。

由于我使用旧版本的驱动程序，它不支持 mongo db 的 SVR 连接字符串，我必须在 mongodb 中使用非 SVR 连接字符串。
