使用WIX安裝Windows服務後，實體框架出現錯誤

Question

我使用Visual Studio 2012創建了Windows Servicec項目，其中包括實體框架6以連接到我的數據庫。我添加了一個新的WIX項目來創建一個安裝包。

如果我以調試模式（從Visual Studio本地）運行項目，它工作正常。但在安裝後，該服務將返回followning錯誤：

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

我是新的Windows安裝XML（WIX），我不知道如何解決這個問題。 我認爲有在WiX工程不對勁的Product.wxs，或somewere ...

這裏是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}" ?>

    </Product> 
</Wix> 

任何幫助，將不勝感激... 提前致謝。

Answer 1

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

這意味着沒有找到名爲「MyEntity」的連接字符串。所以，我假設一個.confg文件丟失。通常，服務用來獲取這種信息的配置文件被命名爲「YourAppName.exe.config」。 將此文件從項目文件夾複製到安裝文件夾/ Program Files/Manufacturer/Name Folder。 你會解決。
