title: Remove DACPAC reference files from project and reference and generate pre-build
body: <p>I have a SQL server database project that I am building using Visual Studio.  The project contains 4 DACPAC references.  The DACPAC files are currently part of the github repository, so could in theory become stale as time goes on.</p>
  <p>I'd like to avoid the references becoming stale and not have to store the files in the repo.</p>
  <p>Therefore, my question consists of 2 parts:</p>
  <ol>
  <li><p>I think I can generate the referenced Dacpacs when developing locally by issuing a pre-build set of commands such as SQlPackage - can anybody think of other approaches that may work?</p>
  </li>
  <li><p>Am I able to do something similar in Azure Devops as a pre-build step, or as part of the build process?</p>
  </li>
  </ol>
