title: C# Multiple projects reference the same dll - Whats the easy way to update the dll?
body: <p>I'm curious how others do it, or if there's an easier way...</p>
  
  <p>I'm having multiple projects which are referencing the same DLL i.e. nhibernate.dll.
  Those dlls are stored in version folders like NHibernate-3.2.0. 
  If a new version comes out and we are going to upgrade to it, we create a new version folder and need to update all referencing projects to the new dll.</p>
  
  <p>Is there some easier way to do that? Like some central project (lets call it REF_PROJ) which references nhibernate and all other projects are only referencing REF_PROJ? 
  So the updating of the new version has only be done at one central place, the REF_PROJ.</p>
