title: tslint is not working in visual studio code
body: <p>I installed the tslint add-on in top of my angularJS project in visual studio code.</p>
  
  <p>The issue that its not working, I can't see any error begin shown in the editor.</p>
  
  <p>I made sure the tslint add-on is enabled in the extensions tab.</p>
  
  <p>I checked in vscode settings and also tslint is enabled for typescript files.</p>
  
  <p>In tslint console I can see this warning:</p>
  
  <pre><code>[Warn  - 10:19:51 PM] vscode-tslint: Cannot read tslint configuration - 'Cannot read property 'findConfigurationPath' of undefined'
  </code></pre>
  
  <p>Can you please help me fix this issue?</p>
  
  <p>Thanks</p>
