title: How to upgrade EF Core Tools
body: <p>When I <code>add-migration</code> i got this warning:</p>
  
  <pre><code>The EF Core tools version '2.1.1-rtm-30846' is older than that of the runtime '2.1.4-rtm-31024'. Update the tools for the latest features and bug fixes.
  </code></pre>
  
  <p>I haven't found any information how can I update this, except with updating DotNET Core SDK, but this hasn't worked for me.</p>
