Also, I have notice that I need to referr to the folder location in the "font-awesome.css" where to find the directory if you created one to hold all the font-awesome files. You can check that to make sure that its looking in the correct place and also make sure you have reference with 'bundles' in the App_Start and Shared/_Layout.cshtml
@font-face {
font-family: 'FontAwesome';`enter code here`
src: url('../Content/fonts/fontawesome-webfont.eot?v=4.2.0');
src: url('../Content/fonts/fontawesome-webfont.eot?#iefix&v=4.2.0') format('embedded-opentype'), url('../Content/fonts/fontawesome-webfont.woff?v=4.2.0') format('woff'), url('../Content/fonts/fontawesome-webfont.ttf?v=4.2.0') format('truetype'), url('../Content/fonts/fontawesome-webfont.svg?v=4.2.0#fontawesomeregular') format('svg');
font-weight: normal;
font-style: normal;
