title: How do I demand a 64-bit agent?
body: <p>In the documentation for Azure Pipelines, it allows for <code>demands</code> to be provided which will force a task to select an agent with <code>capabilities</code> that meet the demands.</p>
  
  <p>However, I can't find a definitive list of the capabilities provided by the Microsoft-hosted agents.</p>
  
  <p>How can I specify a demand that will only allow for 64-bit agents?</p>
