title: How to configure Azure DevOps Pipeline decorators to run pre-tasks in classic pipelines?
body: <p>We have a custom Azure DevOps extension to in order to inject SonarQube pipeline tasks into every definition using the Pipeline Decorator feature. These tasks are a mixutre of both <strong><em>pre</em></strong> and <strong><em>post</em></strong> tasks. </p>
  
  <p>In YAML defined pipelines, the tasks run perfectly, however in Classic pipeline definitions, only the <strong><em>post</em></strong> tasks run, although the classic and YAML pipelines are defined identically (steps, agents, demands, variables etc.).</p>
  
  <p>As this is a relatively new feature of Azure DevOps, there is a lack of documentation, especially regarding classic pipelines.</p>
  
  <p>Is there something that we could possibly be missing for this to happen?</p>
