  # We should cache the .dotnet directory to avoid a .NET banner being
  # printed, and we should cache the main directory because there is a
  # generated main.csproj file that is needed by .NET. Finally we
  # should cache the .nuget directory as well as the build artifacts
  # inside main to avoid a 30s initial compile time.
  #
  # We could optimize further but I don't feel like it right now.
