Challenges with Typescript Integration in Visual Studio 2013

Currently diving into typescript as a newbie while going through the Angular tutorial using Visual Studio 2013 for work, which is also new to me. The frustrating part is that Visual Studio seems to be assuming I am going to use a different language (judging by the red dots and squiggly underlines) which makes it quite challenging and annoying to write and read code.

Despite all the code being accurate and functional, I am strictly following a tutorial so most of it is just copy-pasting.
