SlowCheetah transform fails using Visual Studio Online

We're using SlowCheetah to do app.config transforms for a project. However, when trying to move the build process to Visual Studio Online, I can no longer build the solution. The build fails because the .dll.config file cannot be found. I believe this is caused by SlowCheetah.

Here's what we're using: SlowCheetah 2.5.10.6. As the build template I'm using the TfvcTemplate.12.xaml process. My NuGet version is 2.8 and Package Restore is enabled for the solution.

I've come across a few similar issues but most solutions apply to VS2012 or older versions of SlowCheetah and NuGet.

Update June 17

After looking more carefully at the log file generated by MSBuild, I found that the transform succeeds, and when my project is built, I see this line in the log: Copying file from "obj\Release\Assembly.Worker.csproj-sc.App.config" to "C:\a\bin\Assembly.Worker.dll.config".

However, I also have an Azure cloud service project, which is built next. Here's where the build fails.

This is what I find in the log: C:\a\src\ProjectFolder\Assembly.Azure\Assembly.Azure.ccproj(101,5): error MSB3030: Could not copy the file "..\Assembly.Worker\bin\Release\Assembly.Worker.dll.config" because it was not found.

So apparently SlowCheetah creates a transformed config file and saves it as a .csproj-sc.app.config file, while the Azure project looks for a normal app.config file. Interestingly, building the Azure project locally works fine.

That's likely a bug in Azure targets then. If it doesn't work with SlowCheetah it will fail with BCL NuGet pkg as well since they use the same technique to update app.config. – Sayed Ibrahim Hashimi

In the end I fixed the problem by changing the SlowCheetah.Transforms.targets file in the Properties folder.

At line 157 I inserted the following code to copy the transformed file to the path that Azure expects:

<Copy Condition=" '$(_Sc_HasAppConfigTransform)'=='true' "
  SourceFiles="$(__SC_IntermediateAppConfig)"
  DestinationFiles="$(MSBuildProjectDirectory)\bin\Release\$(MSBuildProjectName).dll.config"
  SkipUnchangedFiles="true" ContinueOnError="false" />
