title: Using vb.net classes in c#
body: <p>How can I create a type in vb.net and use the type in c#?
  I guess I need to compile the vb project and add reference to the dll but have no idea if this is the   right way to do it, or the reference will be valid.
  Doing this is not for fun, we have some vb code and we're considering this option.</p>
