title: How to find top 10 files changed most frequently in a period from TFS 2015 Version Control?
body: <p>My team uses TFS 2015 as an ALM and Version Control system,I want to analyse which files change most frequently.</p>
  
  <p>I found TFS didn't have this functionality out of the box, but TFS2015 has a REST API to query Changesets for files, like this below：</p>
  
  <pre><code>http://{instance}/tfs/DefaultCollection/_apis/tfvc/changesets?searchCriteria.itemPath={filePath}&amp;api-version=1.0
  </code></pre>
  
  <p>There are thousands of files in my Project Repository, querying it one by one is not a good idea, are there any better solution to this question?</p>
