TFS Builder Server missing config file - msbuild

Question

I have a project that builds without errors on our build server (2012). The issue is we are not getting the transformed app.config.
Using transform preview I see that the transform works correctly. In the .csproj file, I see that the app.config and all of the transforms are added and transform on build are set to true.
<ItemGroup>
<None Include="App.config">
<TransformOnBuild>true</TransformOnBuild>
</None>
<None Include="App.Debug.config">
<DependentUpon>App.config</DependentUpon>
<IsTransformFile>True</IsTransformFile>
</None>
<None Include="App.DEV1.config">
<DependentUpon>App.config</DependentUpon>
<IsTransformFile>True</IsTransformFile>
</None>
<None Include="App.PROD.config">
<DependentUpon>App.config</DependentUpon>
<IsTransformFile>True</IsTransformFile>
</None>
<None Include="App.QA1.config">
<DependentUpon>App.config</DependentUpon>
<IsTransformFile>True</IsTransformFile>
</None>
<None Include="App.Release.config">
<DependentUpon>App.config</DependentUpon>
<IsTransformFile>True</IsTransformFile>
</None>
<None Include="App.UAT1.config">
<DependentUpon>App.config</DependentUpon>
<IsTransformFile>True</IsTransformFile>
</None>
Other projects in the build have the correct config files. Here is a relevant section of the build log.
10:53:46.166 66>Target "_CopyAppConfigFile: (TargetId:2226)" in file "C:\Windows\Microsoft.NET\Framework64\v4.0.30319\Microsoft.Common.targets" from project "D:\1_91\Sources\Path1\Path2\Path3\projname.csproj" (target "CopyFilesToOutputDirectory" depends on it):
Building target "_CopyAppConfigFile" completely.
Output file "D:\1_91\Binaries\Path3\projname.exe.config" does not exist.
Task "Copy" (TaskId:1543)
Copying file from "App.config" to "D:\1_91\Binaries\Path3\projname.exe.config". (TaskId:1543)
Done executing task "Copy". (TaskId:1543)
It does not find the transformed config and so it replaces it with the default config. What could I try to fix this issue?

Answer 1

I installed Configuration Transformation and it installed the transform instructions to the csproj file.
