title: Error: Configuration element is not declared
body: <pre><code>?xml version="1.0" encoding="utf-8" ?&gt;
  ****&lt;configuration&gt;****
      &lt;startup&gt; 
          &lt;supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.5" /&gt;
      &lt;/startup&gt;
  &lt;/configuration&gt;
  </code></pre>
  
  <p>The above is one part of encoding in my program, which gives a error. Error is in the second line, which shows me something like a blue lined, </p>
  
  <blockquote>
    <p>configuration element is not declared</p>
  </blockquote>
  
  <p>For what reason it happens like this?</p>
