title: Why do my toolbox items disappear in Visual Studio 2008?
body: <p>I'm working on a solution that contains multiple projects targeting Windows Mobile 5 and standard Windows applications.</p>
  
  <p>Lately when opening up a form in designer the common UI controls (textbox, button, label, etc etc...) have vanished leaving only the controls defined within the project.</p>
  
  <p>Resetting the toolbox has no effect.  A google search suggested deleting the toolbox temp files in the <code>Local Settings\Application Data\Microsoft\VisualStudio\9.0</code>, however this was only successful in bringing back the default controls for Windows Mobile 5.  The WinForms controls are still mysteriously missing.</p>
  
  <p>Also, if I right-click and <em>Select All</em> on the toolbox, all of the WinForms controls do in fact come up, however they're all grayed out.</p>
  
  <p>Has anyone else experienced this?</p>
