title: VSTS Build Task - How To Generate Dropdown List from Result Set
body: <p>As part of my VSTS build/release definition set up, I would like to populate a dropdown list from the results of a preceding query. For instance, I want the query to return a list of all packages from an external repository and let's just say there are a total of 10 packages stored in that repository. </p>
  
  <p>I then want the entire array of 10 packages displayed in a dropdown list, thereby ensuring that they can then be selected individually.</p>
  
  <p>How can I accomplish this?</p>
