title: Xamarin android No resource identifier found for attribute in package
body: <p>I'm currently working on an android core app using xamarin, I have installed android support design 23.4.0.1, and Android.Support.v7.AppCompat 23.4.0.1</p>
  
  <p>And the problem I'm having right now is in this lines:</p>
  
  <pre><code>    app:headerLayout="@layout/nav_header"
      app:menu="@layout/menu_navigation"
  </code></pre>
  
  <p>With the error "No resource identifier found for attribute in package" </p>
  
  <p>I was reading some of the questions already answered in here, but still can't fix the error, maybe because I'm using xamarin, I don't know. </p>
  
  <p>Full code in question:</p>
  
  <pre><code>&lt;?xml version="1.0" encoding="utf-8"?&gt;
