When performing a build you may receive the following error.
error MSB4057: The target "PipelineTransformPhase" does not exist in the project.
Either the path is wrong in your .csproj file or your missing the Microsoft.WebApplication.Targets file on your build server.
If its missing on your build server simply just copy it over from your local machine, from and to the same location.
