我在Visual Studio 2015中创建了Windows应用程序，而我的数据库在SQL Server 2008 R2中。我通过解决方案的属性窗口发布了它。
它在我的笔记本电脑上工作正常。但是，当我要在其他笔记本电脑上安装它时，它显示未处理的异常“底层提供商在打开时失败”。
我在其他笔记本电脑上安装了.NET Framework 4.5。我是否还必须安装SQL服务器？
有没有办法在不安装sql server的情况下成功安装我的应用程序？
编辑 - 这是我的例外。

************** JIT Debugging **************
To enable just-in-time (JIT) debugging, the .config file for this
application or computer (machine.config) must have the
jitDebugging value set in the system.windows.forms section.
The application must also be compiled with debugging
enabled.
For example:
<configuration>
<system.windows.forms jitDebugging="true" />
</configuration>
When JIT debugging is enabled, any unhandled exception
will be sent to the JIT debugger registered on the computer
rather than be handled by this dialog box.
