如何使用新的 VS 2010 配置转换并将它们应用到其他 .config 文件? [英] How to use the new VS 2010 configuration transforms and apply them to other .config files?

问题描述

我已经在我的 web.config 中为我的 connectionStrings 等设置了一些配置转换.但是我已经将我的 web.config 的某些区域分离到单独的文件中，例如 appSettings.config.

I have setup some configuration transforms in my web.config for my connectionStrings, etc. But I have separated out some areas of my web.config into separate files, ex) appSettings.config.

如何配置 Visual Studio 和 MSBuild 以对这些额外的配置文件执行配置转换?

How can I configure Visual Studio and MSBuild to perform config transformations on these additional config files?

我已经按照 web.config 的方法在我的 web 应用程序项目文件中将文件关联在一起，但不会自动应用转换.

I have already followed the approach of the web.config to relate the files together within my web application project file, but transformations are not automatically applied.

<ItemGroup>
    <Content Include="appSettings.Debug.config">
        <DependentUpon>appSettings.config</DependentUpon>
    </Content>
</ItemGroup>

推荐答案

默认情况下，管理转换的目标 (TransformWebConfig) 仅适用于 web.config 文件.

By default the target managing the transformation (TransformWebConfig) works only on web.config file.

要使其在您的 appSettings.config 文件上运行，您必须:

To make it work on your appSettings.config file you'll have to :

• 将文件的 Build Action 设置为 Content
• 使用 ProjectConfigFileName=appSettings.config 和 Configuration=$(Configuration) 调用 MSBuild 目标 TransformWebConfig.

• Set the Build Action of your file to Content
• Call the MSBuild target TransformWebConfig with ProjectConfigFileName=appSettings.config and Configuration=$(Configuration).

要在 web.config 文件转换后为 appSettings.config 调用 MSBuild TransformWebConfig 目标，您需要在项目文件结束:

To call MSBuild TransformWebConfig target for appSettings.config just after the transformation of web.config files, you need to add this at the end of your project file :

<PropertyGroup>
  <!-- Name of your custom config file -->
  <ConfigFileName>appSettings.config</ConfigFileName>
</PropertyGroup>

<PropertyGroup>
  <!-- 
      This property is used to handle circular dependency between
      TransformWebConfig and our custom target TransformAppConfig
  -->
  <FirstRun Condition="$(FirstRun) == ''">true</FirstRun>
</PropertyGroup>

<!-- This target will be called one time after a call to TransformWebConfig -->
<Target Name="TransformAppConfig" 
        AfterTargets="TransformWebConfig"
        Condition="$(FirstRun) == 'true'">

  <MSBuild Projects="$(MSBuildProjectFile)"
           Targets="TransformWebConfig"
           Properties="ProjectConfigFileName=$(ConfigFileName);
                       Configuration=$(Configuration);
                       FirstRun=false"/>
</Target>

<!-- 
    This target will be called one time before PreAutoParameterizationWebConfigConnectionStrings 
    to add $(ConfigFileName) to autoparameterization step
-->
<Target Name="AddToAutoParameterizationStep" 
        BeforeTargets="PreAutoParameterizationWebConfigConnectionStrings">
  <ItemGroup>
    <_WebConfigsToAutoParmeterizeCS Include="@(FilesForPackagingFromProject)"
                           Condition="('%(FilesForPackagingFromProject.Filename)%(FilesForPackagingFromProject.Extension)'=='$(ConfigFileName)') And !%(FilesForPackagingFromProject.Exclude)">
      <TransformOriginalFile>$(AutoParameterizationWebConfigConnectionStringsLocation)original\%(DestinationRelativePath)</TransformOriginalFile>
      <TransformOutputFile>$(AutoParameterizationWebConfigConnectionStringsLocation)	ransformed\%(DestinationRelativePath)</TransformOutputFile>
      <TransformScope>$(_PackageTempDir)\%(DestinationRelativePath)</TransformScope>
    </_WebConfigsToAutoParmeterizeCS>
    <_WebConfigsToAutoParmeterizeCSOuputFiles Include="@(_WebConfigsToAutoParmeterizeCS->'%(TransformOutputFile)')">
    </_WebConfigsToAutoParmeterizeCSOuputFiles>
  </ItemGroup>   
</Target>
