Asp.net InvalidOperationException:未知的连接字符串参数'；SSLMode'；

我刚进入一个Asp.NET web项目，我正在尝试设置应用程序。当我运行应用程序并调用本地主机上的端点时，我得到错误“InvalidOperationException:未知连接字符串参数'SSLMode'

以下是完整的堆栈跟踪：

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，但在我的机器上运行得不好：我们基本上使用的是相同类型的虚拟机。正因为如此，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，我将感谢任何建议。谢谢

问题是，即使我有许可证信息，我的机器上也没有安装devart。。。关闭

PostgreSQL的连接字符串是否已准备就绪，或者您正在对此进行更改？异常是清除，表示它不是连接字符串的属性。但事实上是这样。问题是，即使我有许可证信息，我的机器上也没有安装devart。。。结束
