title: VSIX - Cannot load file or assembly of a referenced dll
body: <p>My question is very similar to <a href="https://stackoverflow.com/questions/12110135/vsix-package-doesnt-include-referenced-projects-dependencies">this one</a>, only that the answer and work-around are not working for me.  Also I am in Visual Studio 2012.</p>
  
  <p>I have a VSPackage which is referencing another project, which is dependent on other dlls.  Everytime time I run my package in debug I get an exception that the other dlls cannot be found.  They are in the output directory, and they are signed.</p>
  
  <p>I tried referencing them directly by the VSPackage project to no avail.</p>
  
  <p>Thoughts?</p>
