    推荐答案

    我测试了UWP应用和SQL Server 2008 R2，并且可以重现您的问题。我还用相同的代码片段，相同的SQL Server配置测试了UWP app与SQL Server 2017之间的连接，它工作得很好。因此，作为一种解决方法，我强烈建议您将SQL Server升级到2017，因为SQL Server 2008 R2已经过时了。

    I tested the connection between UWP app and SQL server 2008 R2, and can reproduce your issue. I also tested the connection between UWP app and SQL server 2017, with the same code snippet, same configuration for SQL server, it worked very well. So that as a workaround I strongly recommend you to upgrade the SQL server to 2017 since SQL server 2008 R2 is already out of date that not supported.

    此外，不要忘记，您在上面的说明中没有提到它。

    Additionally, don't forgget to Enable TCP/IP Network Protocol for SQL Server which you didn't mention it in above description.
