title: Adding additional files to Azure Build Pipeline
body: <p>I have an Azure DevOps Pipeline which pulls from a repository and builds a Visual Studio web project. This is then published to an App Service.</p>
  <p>I have several sensitive configuration files which are not included in the repository (or the VS project) and are stored as 'Secure Files' within the Azure DevOps system.</p>
  <p>I need to include these files in the 'Config/Secure' folder for the package that gets published (within the zip file). I can download them, but no matter what I try, I cannot get these files to be included in the deployment zip file. They only appear in the 'drop' file system and thus I can't seem to deploy them to the Web App.</p>
  <p>Does anyone have any ideas how I can do this? Thanks in advance and Pipeline YAML below:</p>
