How to remove error about glyphicons-halflings-regular.woff2 not found

Question

ASP.NET MVC4 Bootstrap 3 application is running from Microsoft Visual Studio Express 2013 for Web IDE.

Chrome console shows always error

http://localhost:52216/admin/fonts/glyphicons-halflings-regular.woff2
Failed to load resource: the server responded with a status of 404 (Not Found)

This file exists in the fonts directory in the Solution Explorer. Build action is set to "Content" and Copy to Output directory is "Do not copy like in other font files". Bootstrap 3 is added to the solution using NuGet. How to fix this so that this error does not occur? Application shows Glyphicon and FontAwesome icons properly. This error always occurs at application startup.

This problem happens because IIS does not know about woff and woff2 file mime types.

Solution 1:

Add these lines in your web.config project:

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

Solution 2:

On IIS project page:

Step 1: Go to your project IIS home page and double click on MIME Types button:

Step 2: Click on Add button from Actions menu:

Step 3: In the middle of the screen appears a window and in this window you need to add the two lines from solution 1:
