title: VS2010: Use namespace from another project within the solution?
body: <p>I have two projects within a single solution in Visual Studio 2010.  These projects are called Project1 and Project2.  Within these projects, two namespaces are defined, Namespace1 and Namespace2, respectively.</p>
  
  <p>Inside some code within Namespace2, I'd like to use some structs, classes, etc. which I've defined in Namespace1.  Is there any way to do this?</p>
