在Windows 10上本地运行可以正常运行，在Windows Server 2012 R2上运行它会引发以下异常。
代码完全相同，部署完成后我没有将本地文件复制到服务器进行验证。
我在Github的消息来源中四处寻找，希望找到答案，但到目前为止一直无法找到任何线索。最近在服务器上发生的事情只是.NET 4.6的安装，但应用程序始终是为.NET 4.6构建的，现在才开始抛出此异常。在.NET安装之后重新启动（只是为了确定）也已完成。

//Set to -99 since value might range from -5 to max int. Enables inserts with the default sentinel value.
