Font-Awesome error 404 on fonts

Better yet, add this section to your web.config and then those mime types will be automatically added to IIS on any server you deploy to. (The remove is to avoid a duplicate mime type error in case they are already there)

  <system.webServer>
    <staticContent>
      <remove fileExtension=".woff" />
      <mimeMap fileExtension=".woff" mimeType="application/font-woff" />
      <remove fileExtension=".woff2" />
      <mimeMap fileExtension=".woff2" mimeType="font/x-woff" />
    </staticContent>  
  </system.webServer>
