使用WIX安裝Windows服務後，實體框架出現錯誤

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。使用WIX安裝Windows服務後，實體框架出現錯誤

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}" ?>

您的可執行文件只有一個，您還需要部署ParodosServices.exe.settings。你最好（長話題......）把它放在一個單獨的組件中。請注意，在這裏沒用，卸載程序已經做到了，不需要告訴它。 –

幷包括您的exe文件可能具有的任何dll依賴關係。 –

@AdrianoRepetti你是什麼意思，「你的可執行文件只有一個，你還需要部署ParodosServices.exe.settings。你最好（長話題......）把它放在一個單獨的組件中。」？ – pasluc74669

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。
