title: Typescript 1.8 version in Aurelia Framework
body: <p>I am using Aurelia framework. Last night I updated typescript from 1.7 to 1.8 version.</p>
  
  <p>Now I am getting a lot of errors in the error list tab of visual studio.</p>
  
  <p>Errors like:</p>
  
  <pre><code>node_modules/typescript/bin/lib.core.d.ts(83,5): error TS2300: Duplicate identifier 'configurable'.
  node_modules/typescript/bin/lib.core.d.ts(84,5): error TS2300: Duplicate identifier 'enumerable'.
  node_modules/typescript/bin/lib.core.d.ts(85,5): error TS2300: Duplicate identifier 'value'.
  node_modules/typescript/bin/lib.core.d.ts(86,5): error TS2300: Duplicate identifier 'writable'.
  </code></pre>
  
  <p>There are around 20k errors.</p>
  
  <p>I added code to exclude folders in the tsconfig.json but somehow visual studio is not ignoring those folders.</p>
  
  <p>Below are the snapshot for the jspm_packages folder and npm folder.

  <p>Thanks in advance.</p>
