Visual Studio 开发环境中的连接字符串出现相同错误

我们的开发数据库服务器最近获得了自签名证书，因此它自动变得不可信。这导致了上面提到的登录错误。我添加TrustServerCertificate=True到我的连接字符串中，现在它可以工作了。

"Server=TheServerAddress; Database=TheDataBase; User Id=TheUsername; Password=ThePassword; TrustServerCertificate=True"

注意：不建议在生产环境中使用此证书配置。

这为我解决了这个问题。这似乎是 Microsoft.Data.SqlClient 版本 2 中的重大更改。请参阅 https://erikej.github.io/sqlclient/efcore/2020/06/22/sqlclient-2-breaking-changes.html (2认同)
