我有一个连接到SQL Server数据库的控制台应用程序（托管在同一网络中的专用win计算机上），使用.Net核心编写（使用Visual Studio Code），它在Windows上工作得非常好。在Ubuntu/Visual Studio上从.Net Core连接到SqlServer代码
在Ubuntu上运行Visual Studio代码的代码库无法连接到SQL Server实例，说它无法找到服务器。
我可以ping通SQL Server IP并从中获得响应。
另外我可以使用1433端口上的telnet连接到SQLServer实例。
另外，我也按照建议从nuget中提取了System.Data.Common和System.Data.SqlClient，并在建议的连接字符串中设置了MultipleActiveResultSets = False。
只是为了保持完整性，这是试图连接代码：
var connection = new SqlConnection(myConnectionString);
connection.Open();
这是堆栈跟踪：
Unhandled Exception: System.Data.SqlClient.SqlException: A network-related or instance-specific error occurred while establishing a connection to SQL Server. The server was not found or was not accessible. Verify that the instance name is correct and that SQL Server is configured to allow remote connections.

任何想法？
感谢
你的连接字符串是什么样的？您是否使用SQL身份验证？如果您的连接字符串正在使用Windows身份验证而不是SQL身份验证，那么您可能会遇到问题。 –
我正在使用SQL身份验证。 “SERVERIP \\ MSSQLSERVER，1433; Database = DBName; User = UIsername; Password = password; MultipleActiveResultSets = False” –
