body: <p>Microsoft Documentation explains the use of parameters in Yaml Pipeline jobs as</p>
  
  <pre><code># File: azure-pipelines.yml
  trigger:
  - master
  
  extends:
      template: simple-param.yml
      parameters:
          yesNo: false # set to a non-boolean value to have the build fail
  </code></pre>
  
  <p>But instead of statically specifying the value of yesNo: I'd prefer to load it from a completely separate json config file. Preferably a json file that both my Build Job and my Application could share so that parameters specified for the Application could also be used in the Build Job.</p>
  
  <p>Thus the question:
  How do I load values from a .json file into a Devops Yaml Pipeline Parameter?</p>
