title: VS2015 Angular2 intellisense not working
body: <p>I'm using Visual Studio 2015 Community and working on an Angular2 application. Recently I updated Typescript to version 2.0.3 and since then IntelliSense and formatting are not working for Typescript nor Angular2. Editor recognizes keywords, but I cannot see Angular2 types, cannot Go To Defenition, etc. </p>
  
  <p>During an update of Typescript, I changed System Environment variable for Typescript from <code>C:/.../Typescript/1.0</code> to <code>C:/.../Typescript/2.0</code>.</p>
  
  <p>I tried reverting it back, but with no success. Some of the workarounds included re-installing Visual Studio, but I cannot do that. </p>
  
  <p>Does anyone know what could be done to fix the issue?</p>
