title: Visual Studio generates "Settings1.Designer.vb" when I change a configuration setting
body: <p>Sometimes (not always), when I edit a setting in the "My Project" page, when I add one or edit a value from there, I get an error : <code>'Settings is ambiguous between declaration in Modules '&lt;project&gt;.My.MySettingsProperty' and '&lt;project&gt;.My.MySettingsProperty'</code></p>
  
  <p>Visual Studio creates a duplicate of <code>My Project\Settings.Designer.vb</code>, and registers both of them in the <code>.vbproj</code> file.</p>
  
  <p>When this happens, I need to delete Settings.Designer.vb, remove the "1" in Settings1.Designer.vb, and remove the references to it in the vbproj file.</p>
  
  <p>It also happens when I edit a Telerik ORM model (a designer.vb file copied to designer1.vb), with the added problem that in that case, the designer.vb file is empty afterwards.</p>
  
  <p>Here is another description of the problem, by somebody else (who doesn't have an answer since 2009 except mine) : <a href="http://social.msdn.microsoft.com/Forums/en-AU/vbide/thread/29e7b9ff-5cdc-456b-9d2f-bc85145e8eaf" rel="noreferrer">http://social.msdn.microsoft.com/Forums/en-AU/vbide/thread/29e7b9ff-5cdc-456b-9d2f-bc85145e8eaf</a></p>
  
  <p>Can you think of a possible source, but more importantly, of a possible fix ?</p>
  
  <p>I'm using Visual Studio 2008 Standard, and this problem did not happen a few months ago.</p>
  
  <p>Thanks</p>
