我创建了Vishal Joshi发布的另一个替代方案，其中将构建动作更改为内容的需求被删除，并实现了对ClickOnce部署的基本支持。我说基本，是因为我没有彻底测试它，但它应该在典型的ClickOnce部署场景中工作。

该解决方案由一个MSBuild项目组成，一旦导入到现有的windows应用程序项目(*.csproj)，将构建过程扩展到考虑app.config转换。

你可以在Visual Studio App.config XML Transformation上阅读更详细的解释，MSBuild项目文件可以从GitHub下载。

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>

So I ended up taking a slightly different approach. I followed Dan's steps through step 3, but added another file: App.Base.Config. This file contains the configuration settings you want in every generated App.Config. Then I use BeforeBuild (with Yuri's addition to TransformXml) to transform the current configuration with the Base config into the App.config. The build process then uses the transformed App.config as normal. However, one annoyance is you kind of want to exclude the ever-changing App.config from source control afterwards, but the other config files are now dependent upon it.

  <UsingTask TaskName="TransformXml" AssemblyFile="$(MSBuildExtensionsPath)\Microsoft\VisualStudio\v$(VisualStudioVersion)\Web\Microsoft.Web.Publishing.Tasks.dll" />
  <Target Name="BeforeBuild" Condition="exists('app.$(Configuration).config')">
    <TransformXml Source="App.Base.config" Transform="App.$(Configuration).config" Destination="App.config" />
  </Target>

你可以为每个配置使用一个单独的配置文件，例如app.Debug。config, app.Release.config，然后在项目文件中使用配置变量:

<PropertyGroup>
    <AppConfig>App.$(Configuration).config</AppConfig>
</PropertyGroup>

这将根据您正在构建的配置创建正确的ProjectName.exe.config文件。

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

只是对现在到处张贴的解决方案做了一点改进:

<UsingTask TaskName="TransformXml" AssemblyFile="$(MSBuildExtensionsPath)\Microsoft\VisualStudio\v$(VisualStudioVersion)\Web\Microsoft.Web.Publishing.Tasks.dll" />

也就是说，除非你打算永远使用当前的VS版本
