title: Build only projects which are changed in a solution -Azure CI pipeline - YAML
body: <p>I have multiple projects under a solution,</p>
  
  <pre><code>ProjectA.csproj
  projectB.csproj
  projectC.csproj
  </code></pre>
  
  <p>I have created a YAML CI build pipeline for this solution with trigger from Master Branch</p>
  
  <p>"trigger: - Master"</p>
  
  <p>Whenever a check-in happens to Master for any of the project above, it triggers the CI pipeline and create artifacts for all the above individual projects.</p>
  
  <p>Question - can I only build projects which have changes using the same single YAML file for the solution?</p>
