title: Visual Studio is skipping to every other line while debugging
body: <p>I try to step through my code now, Visual Studio skips every other line.  </p>
  
  <p>(I know it is every other because when I have a ForEach loop it will hit the lines that it skipped on later iterations.)</p>
  
  <p>Is there any logical reason for Visual Studio to skip every other line? </p>
  
  <p><strong>UPDATE:</strong> I have added a youtube video of this happening <a href="http://www.youtube.com/watch?v=CIWelNpWUcE&amp;feature=youtu.be" rel="nofollow">here</a>.  This only happens in this one solution.  I have tried rebuilding, cleaning then rebuilding... I am at a loss for what to do.</p>
  
  <p><strong>UPDATE:</strong> Several comments have asked for a code sample.  I am posting one, but I really don't think the code is the issue.  I have many thousands of lines of code and it is skipping lines anywhere I put a breakpoint.</p>
  
  <p>Here is a code sample just incase it could somehow matter:</p>
  
  <pre><code>foreach (string commentText in comment.CommentLines)
  {
      // Set the base path for this segment
      basePath = rootPath + XPathsForComment.OrderRoot.Expression + "[@Id='" + index + "']/";
      // Sequence
      XPathToXML.Set(document, basePath + XPathsForComment.Sequence.Expression, commentIndex.ToString());    
      // Comment Type
      XPathToXML.Set(document, basePath + XPathsForComment.TypeCode.Expression, CommentCodes.CommentCode);    
      // Comment
      XPathToXML.Set(document, basePath + XPathsForComment.TextAttribute.Expression, commentText);
      // Empty xmlns
      XPathToXML.Set(document, basePath + XPathsForComment.XmlnsAttribute.Expression, "");
      commentIndex++;
      index++;
  }
  </code></pre>
  
  <p>Things I have tried:</p>
  
  <ul>
  <li>Rebooting</li>
  <li>Deleting the Folder that holds the source and getting it from Source Control again.</li>
  <li>Switching from Debug to Release and back to Debug (doing cleans an Rebuilds each time)</li>
  <li>Clean and Rebuild in Debug.</li>
  </ul>
