title: base type is not CLS-compliant in Third Party Control
body: <p>I have a control that I purchased.  When I tried to inherit from the control I get this message:</p>
  
  <pre>Warning: 'MyNamespace.MyFile': base type 'Mooseworks.UI.MwTextBox' is not CLS-compliant</pre>
  
  <p>Is there any way around this besides asking the vendor of my control to make their control CLS compliant?</p>
