Make any text file that contains html treated as an html file Follow

I am developing with asp.net MVC and I am not looking for code completion for .net syntax, or anything .net related. I am simply looking for a way for WebStorm to treat my cshtml file as html.  I am newer to WebStorm, and see that I can inject languages, but can't find this option for entire files.  I can just change the extension back and forth from cshtml to html when in WebStorm, but I am hoping for an easier method.
