title: Cannot Assign Work Items to Releases in Azure DevOps
body: <p>I come from using Rally and Pivotal Tracker. In both I could assign work items to Releases as a planning tool, and to have a historical record of those work items that were deployed. </p>
  
  <p>Even with all the highly-specific guidance from Microsoft about Azure DevOps, it is silent how to organize work against future Releases. I can't see a place to even associate a work item to a Release. Is there something I am missing in all the documentation, or is there some workaround strategy more robust than just using tags to pro-actively plan against releases? Or is Microsoft's expectation that I use some separate product management tool to manage work items against Releases?</p>
