使用.net创建了一个非常简单的Windows窗体应用程序，并连接到本地MDF文件以进行基本的CRUD操作。这一切都在我的电脑上按预期工作。
我已将此应用程序传递给朋友进行测试（非开发机器）并且运行它时遇到问题..
System.Data.SqlClient.SqlException (0x80131904): 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. (provider: SQL Network Interfaces, error: 52 -
Unable to locate a Local Database Runtime installation. Verify that SQL
Server Express is properly installed and that the Local Database
Runtime feature is enabled.) --->
我认为他们还需要安装SQL Express才能使其正常工作吗？
