Summary

When I upgraded to the MongoDB.Driver 3.0.0, I couldn't connect to the replica set cluster(ver: 8.0.1) I created locally using Docker. I created a minimal reproducible demo on GitHub, which includes my docker-compose configuration file.

Exception Message:

“System.TimeoutException”类型的异常在 System.Private.CoreLib.dll 中发生，但未在用户代码中进行处理
