title: tf.exe checkin does not find any pending changes
body: <p>I'm trying a simple TFS 2015 checkin automation. I have a local workspace mapped to a local folder. In that folder, I added some files and deleted one. What I want is to checkin those changes</p>
  
  <p>I run this command</p>
  
  <pre><code>tf.exe checkin &lt;folder&gt; /recursive
  </code></pre>
  
  <p>The result (unexpected) is "no pending changes"</p>
  
  <p>If I run the following command</p>
  
  <pre><code>tx.exe status &lt;folder&gt;
  </code></pre>
  
  <p>I get the list of changes expected.</p>
  
  <p>If I look in Visual Studio source code explorer, I cannot see my changes but if I try to add items in the TFS folder, I can see new files.</p>
  
  <p>Can you help me to understand how I can automate this checkin scenario?</p>
  
  <p>EDIT : based on this <a href="https://stackoverflow.com/questions/34172812/check-in-delete-files-renamed-files-moved-files-to-tfs-using-command-line">SO thread</a>, it seems it is not possible to achieve this with local workspace. Can someone confirm?</p>
