这现在可以与本文中处理的Visual Studio AddIn一起工作:SlowCheetah - Web。config转换语法现在适用于任何XML配置文件。

You can right-click on your web.config and click "Add Config Transforms." When you do this, you'll get a web.debug.config and a web.release.config. You can make a web.whatever.config if you like, as long as the name lines up with a configuration profile. These files are just the changes you want made, not a complete copy of your web.config. You might think you'd want to use XSLT to transform a web.config, but while they feels intuitively right it's actually very verbose. Here's two transforms, one using XSLT and the same one using the XML Document Transform syntax/namespace. As with all things there's multiple ways in XSLT to do this, but you get the general idea. XSLT is a generalized tree transformation language, while this deployment one is optimized for a specific subset of common scenarios. But, the cool part is that each XDT transform is a .NET plugin, so you can make your own. <?xml version="1.0" ?> <xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="1.0"> <xsl:template match="@*|node()"> <xsl:copy> <xsl:apply-templates select="@*|node()"/> </xsl:copy> </xsl:template> <xsl:template match="/configuration/appSettings"> <xsl:copy> <xsl:apply-templates select="node()|@*"/> <xsl:element name="add"> <xsl:attribute name="key">NewSetting</xsl:attribute> <xsl:attribute name="value">New Setting Value</xsl:attribute> </xsl:element> </xsl:copy> </xsl:template> </xsl:stylesheet> Or the same thing via the deployment transform: <configuration xmlns:xdt="http://schemas.microsoft.com/XML-Document-Transform"> <appSettings> <add name="NewSetting" value="New Setting Value" xdt:Transform="Insert"/> </appSettings> </configuration>

建议的解决方案将不工作时，类库配置文件引用从另一个项目(在我的情况下，它是Azure工作项目库)。它不会将正确转换后的文件从obj文件夹复制到bin\##configuration-name##文件夹。为了使它在最小的变化下工作，你需要将AfterCompile target改为BeforeCompile:

<Target Name="BeforeCompile" Condition="exists('app.$(Configuration).config')">

我写了一个很好的扩展来自动化app.config转换，就像在Web应用程序项目配置转换中构建的那样

这个扩展的最大优势是，你不需要在所有的构建机器上安装它

在Visual Studio中从市场安装“配置转换工具”并重新启动VS.你也可以看到app.config的菜单预览转换。

根据我的经验，我需要使环境特定的东西是像连接字符串、appsettings和通常的smpt设置。配置系统允许在单独的文件中指定这些内容。所以你可以在app.config/web.config中使用这个:

 <appSettings configSource="appsettings.config" />
 <connectionStrings configSource="connection.config" />
 <system.net>
    <mailSettings>
       <smtp configSource="smtp.config"/>
    </mailSettings>
 </system.net>

我通常所做的是将这些特定于配置的部分放在单独的文件中，放在名为ConfigFiles的子文件夹中(取决于是在解决方案根目录中还是在项目级别中)。我为每个配置定义一个文件，例如smtp.config.Debug和smtp.config.Release。

然后你可以像这样定义一个预构建事件:

copy $(ProjectDir)ConfigFiles\smtp.config.$(ConfigurationName) $(TargetDir)smtp.config

在团队开发中，您可以通过在约定中包含%COMPUTERNAME%和/或%USERNAME%来进一步调整。

当然，这意味着目标文件(x.config)不应该放在源代码控制中(因为它们是生成的)。你仍然应该将它们添加到项目文件中，并将它们的输出类型属性设置为“始终复制”或“如果更新则复制”。

简单，可扩展，适用于所有类型的Visual Studio项目(控制台，winforms, wpf, web)。
