title: MSBuild Click-Once issues with manifest
body: <p>I am getting the following error when I publish my ClickOnce application with MSBuild. I have a pre-publish task which copys the correct app.config file into the project before the publish and this is the only thing that I think could be causing this error. How can I correct this?</p>
