title: Azure DevOps Trigger build on release/{version} branch
body: <p>For Azure DevOps, how can you automatically build when you create a release branch in the formation release/{version}?</p>
  
  <p>Looking at the triggers tab of a build, the filter allows me to select a branch, but that is only for pre-defined branches, and not a branch type / format.</p>
  
  <p>I don't know yet what the branch name will be as it will follow a version string format like release/{major}.{minor}.</p>
  
  <p>Any ideas how this can be achieved?</p>
