title: Visual Studio not displaying compile time errors in editor
body: <p>For example, when I write:</p>
  
  <pre><code>string x = "turtle";
  x.Go();
  </code></pre>
  
  <p>There is no red squiggly line detecting the absence of the Go() method on String.</p>
  
  <p>Only when I compile does the error get detected.</p>
  
  <p>I've just upgraded to Windows 7, I have Visual Studio 2008.</p>
  
  <p>In my old environment the errors were detected before the actual compile.</p>
  
  <p>Is there a setting that I am missing?</p>
  
  <p>EDIT: "Tools -> Options -> Text Editor -> C# -> Underline errors in the editor" is checked.</p>
  
  <p>I dont have the "Live Semantic" option. Maybe I need to go to SP1?</p>
