title: '&' in password illegal character in web.config file
body: <p>I have a web.config file, in connection string attribute, I have an '&amp;' in password which creates error in parsing web.config file.</p>
  
  <p>code:</p>
  
  <pre><code>&lt;connectionStrings&gt;
      &lt;clear/&gt;
  
      &lt;add name="FamefaceDB" connectionString="Data Source=ec2-204-236-162-54.us-west-1.compute.amazonaws.com;Initial Catalog=famefacedb;User ID=Administrator;Password= t2kfPcn6?D&amp; "/&gt;
    &lt;/connectionStrings&gt;
  </code></pre>
  
  <p>The '&amp;' in password is illegal and says hexadecimal value is illegal in XML file.</p>
  
  <p>Is there any solution to this?</p>
