Compression Filter on MVC Page is not working

Question

I have a MVC5 Web Application. I used Compression Filter on my controller from This Site

Everything works but looks like still my page is not compressed. I use YSlow Chrome extension to check my page but it reports that GZip compression is not applied on my page. I'm testing my web app in VS 2015 (debug mode) using IIS Express.

Am I doing something wrong? or YSlow extension is wrong?

In your web.config:

<?xml version="1.0" encoding="utf-8"?>
<configuration>
  <system.webServer>
    <urlCompression doStaticCompression="true" doDynamicCompression="true" />
    <httpCompression>
      <dynamicTypes>
        <clear />
        <add enabled="true" mimeType="text/*"/>
        <add enabled="true" mimeType="message/*"/>
        <add enabled="true" mimeType="application/x-javascript"/>
        <add enabled="true" mimeType="application/javascript"/>
        <add enabled="true" mimeType="application/json"/>
        <add enabled="false" mimeType="*/*"/>
        <add enabled="true" mimeType="application/atom+xml"/>
        <add enabled="true" mimeType="application/atom+xml;charset=utf-8"/>
      </dynamicTypes>
      <staticTypes>
        <clear />
        <add enabled="true" mimeType="text/*"/>
        <add enabled="true" mimeType="message/*"/>
        <add enabled="true" mimeType="application/javascript"/>
        <add enabled="true" mimeType="application/atom+xml"/>
        <add enabled="true" mimeType="application/xaml+xml"/>
        <add enabled="true" mimeType="application/json"/>
