title: Amazon.Util.EC2InstanceMetadata returns null
body: <p>I Upgrade EC2 to IMDSv2 and since then some of the functionality of EC2 and I can not use IMD (Instance meta data) class</p>
  <p>For example:
  I can't get the region name:
  <code>Amazon.Util.EC2InstanceMetadata.Region</code>
  It returns null,
  actually I get null for instance id either:
  <code>Amazon.Util.EC2InstanceMetadata.InstanceID</code></p>
  <p>Has anyone encountered a problem? Or know of ways to solve it, or find alternative ways to achieve region and so on?</p>
