Request Language Support: grammar "ASP.NET Razor" and extension "cshtml"

Hi, was wondering if support for the ASP.NET Razor language would be possible.

I've installed this package https://atom.io/packages/language-cshtml for the language support.

The beautifier for the HTML seems to to the trick (When selecting HTML as the grammar for the file) I just can't seem to get it auto-detecting when I followed the steps to add a new language to the package though (https://github.com/Glavin001/atom-beautify/wiki/Add-an-unsupported-language-using-an-existing-beautifier)

I've added a simple hello world snippet for testing

<div class="@(Model.Hello)">
  <span>
    @Html.Raw(Model.HelloWorld)

       @{
            //This is an inline code block
            var hellloWord = "Hello world";
           }   
   </span>
</div>

Any help would really be appreciated
