title: Error using Settings file.
body: <p>I'm trying to use a settings file in VS 2013 to store the text of textBox1.Text and then re-input it when you open the application again. </p>
  
  <p>I have it setup like this. </p>
  
  <p>Settings file is here: <a href="http://i.gyazo.com/e3aef293c3b8dbdfab269718de81a310.png" rel="noreferrer">http://i.gyazo.com/e3aef293c3b8dbdfab269718de81a310.png</a></p>
  
  <p>On public Form1() I have this to read the text. </p>
  
  <pre><code>    textBox1.Text = Properties.Settings.Default.aaa;
  </code></pre>
  
  <p>then on saving it I have it like this.</p>
  
  <pre><code>    if (checkBox1.Checked)
      {
          Properties.Settings.Default.aaa = textBox1.Text;
      }
  </code></pre>
  
  <p>But I get the error</p>
  
  <pre><code> 'WindowsFormsApplication1.Properties.Settings' does not contain a definition for 'aaa' and no extension method 'aaa' accepting a first argument of type 'WindowsFormsApplication1.Properties.Settings' could be found (are you missing a using directive or an assembly reference?)
  </code></pre>
  
  <p>Thanks for the help.</p>
