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>

我尝试了几种解决方案，下面是我个人发现的最简单的一个。 Dan在评论中指出，原来的帖子属于Oleg sych -谢谢，Oleg!

以下是使用说明:

1. 将每个配置的XML文件添加到项目中。

通常你会有调试和发布配置，所以把你的文件命名为App.Debug.config和App.Release.config。在我的项目中，我为每种环境创建了一个配置，所以您可能想尝试一下。

2. 卸载项目并打开.csproj文件进行编辑

Visual Studio允许您在编辑器中编辑.csproj文件——您只需要首先卸载项目。然后右键单击它并选择Edit <ProjectName>.csproj。

3.绑定程序。*。配置文件到主App.config

找到包含所有App.config和App.*的项目文件部分。配置引用。你会注意到它们的构建动作被设置为None，这是可以的:

<None Include="App.config" />
<None Include="App.Debug.config" />
<None Include="App.Release.config" />

接下来，让所有特定于配置的文件都依赖于主App.config，这样Visual Studio就可以像对设计器和代码隐藏文件一样对它们进行分组。

将上面的XML替换为下面的XML:

<None Include="App.config" />
<None Include="App.Debug.config" >
  <DependentUpon>App.config</DependentUpon>
</None>
<None Include="App.Release.config" >
  <DependentUpon>App.config</DependentUpon>
</None>

4. 激活转换魔法(对于VS2019等Visual Studio版本仍然是必要的)

在文件结束后

<Import Project="$(MSBuildToolsPath)\Microsoft.CSharp.targets" />

在期末考试之前

</Project>

插入以下XML——请注意，要进行正确的转换需要两个步骤:

  <UsingTask TaskName="TransformXml" AssemblyFile="$(MSBuildExtensionsPath32)\Microsoft\VisualStudio\v$(VisualStudioVersion)\Web\Microsoft.Web.Publishing.Tasks.dll" />
  <Target Name="BeforeBuild" Condition="Exists('App.$(Configuration).config')">
    <!-- Generate transformed app config and replace it: will get the <runtime> node and assembly bindings properly populated -->
    <TransformXml Source="App.config" Destination="App.config" Transform="App.$(Configuration).config" />
  </Target>
  <Target Name="AfterBuild" Condition="Exists('App.$(Configuration).config')">
    <!-- Generate transformed app config in the intermediate directory: this will transform sections such as appSettings -->
    <TransformXml Source="App.config" Destination="$(IntermediateOutputPath)$(TargetFileName).config" Transform="App.$(Configuration).config" />
    <!-- Force build process to use the transformed configuration file from now on.-->
    <ItemGroup>
      <AppConfigWithTargetPath Remove="App.config" />
      <AppConfigWithTargetPath Include="$(IntermediateOutputPath)$(TargetFileName).config">
        <TargetPath>$(TargetFileName).config</TargetPath>
      </AppConfigWithTargetPath>
    </ItemGroup>
  </Target>

现在你可以重新加载项目，构建它，享受App.config转换!

FYI

确保你的App.*。配置文件有如下正确的设置:

<?xml version="1.0" encoding="utf-8"?>
<configuration xmlns:xdt="http://schemas.microsoft.com/XML-Document-Transform">
     <!--magic transformations here-->
</configuration>

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。

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')">

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>
