title: How to fix Error: "Could not find schema information for the attribute/element" by creating schema
body: <p>I have a windows forms application written in VS2010 with C# and get the following errors in the <code>app.config</code> file:</p>
  
  <pre class="lang-none prettyprint-override"><code>Message 4   Could not find schema information for the attribute 'name'
  Message 8   Could not find schema information for the attribute 'name'
  Message 12  Could not find schema information for the attribute 'name'
  Message 5   Could not find schema information for the attribute 'serializeAs'
  Message 15  Could not find schema information for the element 'CCP_Utility.Settings1'
  Message 2   Could not find schema information for the element 'CCP_Utility.Properties.Settings'
  Message 3   Could not find schema information for the element 'setting'
  Message 1   Could not find schema information for the element 'userSettings'
  Message 6   Could not find schema information for the element 'value'
  </code></pre>
  
  <p>What do I have to change in the code to fix this issue? Where can I edit what's in <code>CCP_Utility.Settings1</code> and <code>CCP_Utility.Properties.Settings</code> ?</p>
  
  <p>Here's the <code>app.config</code> code: </p>
