title: Visual Studio not showing typescript errors
body: <p>I am running into s strange problem. I have VS2013 installed with typescript. When I click on save button of a <code>.ts</code> file, the ts compiler is invoked, but VS does not show any ts errors. If the compiler fails I just get a message <code>"Input file contained semantic errors"</code>. </p>

  <p>Now I don't know where the errors are. Does someone know how to fix this, so I can see the actual errors?</p>
