我有一种情况，我们有一个使用便携式区域和T4MVC的解决方案，它有一个单独的 T4MVC 项目，其中为 7 个便携式区域和主 MVC3 应用程序生成了所有文件。我们已按照此处的说明进行操作，我们会在构建解决方案时自动生成类。

虽然在 VS2010 中，这在调试和发布版本中都可以正常工作，但我遇到问题的地方是我试图让它在 TeamCity 上运行。

我已按照此处在构建服务器上设置 T4 的说明进行操作，如果在构建服务器上运行 msbuild，我可以看到它能够启动 TextTemplate.exe 并查看生成文件，问题是它永远找不到文件进行改造。

在执行与在 TeamCity 上运行的相同构建脚本时，我设法在本地计算机上重现了相同的行为。

<?xml version="1.0" encoding="utf-8"?>
<Project ToolsVersion="4.0" xmlns="http://schemas.microsoft.com/developer/msbuild/2003" DefaultTargets="Build">

  <PropertyGroup>
    <Configuration>Release</Configuration>
    <TransformOnBuild>true</TransformOnBuild>
    <TransformFile>T4MVC\T4MVC.tt</TransformFile>
    <OverwriteReadOnlyOutputFiles>true</OverwriteReadOnlyOutputFiles>
  </PropertyGroup>


  <ItemGroup>
    <None Include="T4MVC\T4MVC.tt">
      <OutputFilePath>$(MSBuildProjectDirectory)\T4MVC</OutputFilePath>
    </None>
  </ItemGroup>

  <ItemGroup>
    <ProjectsToBuild Include="**\*proj" Exclude="ThemeGenerator\**" />
  </ItemGroup>

  <Import Project="$(MSBuildExtensionsPath)\Microsoft\VisualStudio\TextTemplating\v10.0\Microsoft.TextTemplating.targets" />

  <Target Name="Clean">
    <ItemGroup>
      <BinFiles Include="*\bin\*.*" />
    </ItemGroup>
    <Delete Files="@(BinFiles)" />
  </Target>

  <Target Name="Build" DependsOnTargets="Clean;Transform">
    <MSBuild Projects="@(ProjectsToBuild)"
             ContinueOnError="false"
             Properties="Configuration=$(Configuration)" /> 
  </Target>
</Project>

执行此操作时，我从 msbuild 中获得以下输出，并设置了 /v:diag：

看起来，在构建服务器上，T4 似乎无法找到它需要引用以生成必要类的项目。我尝试了输入文件夹和程序集引用的各种组合，但发现无法让 T4 “看到”它需要的文件。

有人知道如何解决这个问题吗？

坦率地说，我不确定你是否可以让它工作，因为 T4MVC 需要 VS 主机才能访问 DTE 对象模型。请参阅此相关线程：Using T4MVC with build script

如果 David Ebbo 是正确的，请在构建服务器上从命令行运行 VS (devenv.exe)。

例如，您也不能使用 msbuild 构建 .vdproj 安装程序项目，因此我们在构建服务器上从命令行运行 VS 来构建安装程序...
