title: Getting "type or namespace name could not be found" but everything seems ok?
body: <p>I'm getting a:</p>
  
  <blockquote>
    <p>type or namespace name could not be found</p>
  </blockquote>
  
  <p>error for a C# WPF app in VS2010. This area of code was compiling fine, but suddenly I'm getting this error. I've tried removing the Project Reference and the <code>using</code> statement, shutting VS2010 and restarting, but still I have this issue.</p>
  
  <p>Any ideas why this might be occurring, where it seems like I'm doing the right thing re Reference &amp; <code>using</code> statement?</p>
  
  <p>I also noted in VS2010 that intellisense for that namespace is working ok, so it seems like VS2010 has the project reference and is seeing the namespace on one hand, but during compile doesn't see it?</p>
