title: Code auto-complete does not work for one specific class
body: <p>Like the title says, my code isn't auto completing in one specific class in my project which is really terrible for a beginning programmer like me.</p>
  
  <p>I've tried both <kbd>Ctrl</kbd> + <kbd>Alt</kbd> + <kbd>Space</kbd> and going to Tools -> Text Editor -> C# -> IntelliSense.  Here "Show completion list after a character is typed" is checked.</p>
  
  <p>Note: <kbd>Ctrl</kbd> + <kbd>Alt</kbd> + <kbd>Space</kbd> does work in other classes, if that is of any help.</p>
  
  <p>The relevant code is:</p>
  
  <pre><code>namespace AudioDevices.Devices
  {
      class CdDiscMan : DisplayAudioDevice
      {
          private readonly int mBSize = 700;
          private bool isEjected = false;
  
          public CdDiscMan(int serialId)
          {
              base.SerialID = serialId;
          }
  
          public void Eject()
          {
              isEjected = !isEjected;
          }
  
          public int MbSize
          {
              get { return mBSize; }
          }
          public bool IsEjected
          {
             get { return isEjected; }
          }
      }
  }
  </code></pre>
  
  <p>Upon request, a class in which the auto-complete still functions:</p>
  
  <pre><code>namespace AudioDevices
  {
  
  public class Track
  {
      private category style;
      private int id;
      private string name, artist, albumSource;
      private Time length;
  
  
      public Track()
      {
  
      }
      public Track(int id)
      {
          this.id = id;
      }
      public Track(int id, string name)
      {
          this.id = id;
          this.name = name;
      }
      public Track(int id, string artist, string name)
      {
          this.id = id;
          this.artist = artist;
          this.name = name;
      }
  
      public string GetLength()
      {
          return length.ToString();
  
      }
      public int GetLengthInSeconds()
      {
          return length.Seconds +
              (length.Minutes * 60) +
              (length.Hours * 3600);
      }
  }
  }
  </code></pre>
