InvalidOperationException：未知的连接字符串参数“SSLMode”

Question

我刚刚进入了一个 Asp.NET 网络项目，我正在尝试设置应用程序。当我运行应用程序并在 localhost 上调用端点时，我收到错误“InvalidOperationException: Unknown connection string parameter 'SSLMode'”。

这是完整的堆栈跟踪：

该项目使用 postgres 数据库和 dotConnect。该应用程序在其他同事的机器上运行得很好，但在我的机器上却不行：我们基本上使用的是相同类型的虚拟机。因此，我真的不想更改代码中的任何内容以使应用程序运行。我的机器上安装了 dotConnect。如果有人有类似的问题，我会很感激任何建议。谢谢！
