title: Can't locate MLContext
body: <p>I'm following the ML.Net cookbook "<a href="https://github.com/dotnet/machinelearning/blob/master/docs/code/MlNetCookBook.md#what-if-my-training-data-is-not-in-a-text-file" rel="nofollow noreferrer">What if my training data is not in a text file</a>."</p>
  
  <p>The code includes the line:</p>
  
  <pre><code>var mlContext = new MLContext();
  </code></pre>
  
  <p>However, the class <code>MLContext</code> is not found. How can I resolve that problem?</p>
