使用 WIX 安装 Windows 服务后实体框架出错

Question

我使用 Visual Studio 2012 创建了一个 Windows Servicec 项目，包括 Entity Framework 6 以连接到我的数据库。我添加了一个新的 WIX 项目来创建安装包。

如果我在调试模式下运行项目（在 Visual Studio 的本地），它工作正常。但是安装后服务返回如下错误：

No connection string named 'MyEntities' could be found in the application config file.

我是 Windows 安装 XML (WIX) 的新手，我不知道如何解决这个问题。 我认为 Product.wxs 有问题，或者 WIX 项目中有问题...

这是 Product.wxs：

    <?xml version="1.0" encoding="UTF-8"?>
<!-- The name of the product -->
<?define Name = "MyService" ?>
<!-- The manufacturer, for setup package publisher and folder info -->
<?define Manufacturer = "MyCompanyName" ?>
<!-- The version number of this setup package-->
<?define Version = "1.0.1" ?>
<!-- UpgradeCode must be unique and not changed once the first version of the program is installed. -->
<?define UpgradeCode = "{1240E0CD-B3D2-44A7-B064-11B3C0709D69}" ?>

No connection string named 'MyEntities' could be found in the application config file.

这意味着没有找到名为“MyEntity”的连接字符串。所以，我假设一个 .confg 文件丢失了。通常，服务用来获取此类信息的配置文件名为“YourAppName.exe.config”。 将此文件从项目文件夹复制到安装文件夹 /Program Files/Manufacturer/Name 文件夹。 你会解决的。
