c# - 我无法在另一台电脑上运行我的应用程序

Question

我用 C# 编写了一个程序，我使用数据库作为本地数据库和 Entity Framework 。我完成了程序并创建了一个安装程序项目来部署它。我将数据库 (.sdf) 文件包含到安装程序项目中的模型文件夹中，并将所有 dll 文件包含到 C:\Program Files\Microsoft SQL Server Compact Edition\v3.5 的 Application 文件夹中

我的连接字符串在 App.Config 文件中是这样的:

    <configuration>
  <connectionStrings>
    <add name="ApplicationEntities" connectionString="metadata=res://*/Model.Model1.csdl|res://*/Model.Model1.ssdl|res://*/Model.Model1.msl;provider=System.Data.SqlServerCe.3.5;provider connection string=&quot;Data Source=|DataDirectory|\Model\ApplicationDatabase.sdf&quot;" providerName="System.Data.EntityClient" />
  </connectionStrings>
</configuration>

当我在任何其他电脑上安装程序并运行程序时，我遇到了这样的异常:

************** 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.

我在网上找遍了，没有找到任何解决方法。你能帮帮我吗？

您必须在计算机上安装 SQL Server Compact 3.5 运行时。您可以将压缩版的安装程序包含到您自己的安装程序中。
