title: Visual Studio : build not referenced plugin project
body: <p>I'm working on a WPF application that loads plugin assemblies on runtime.</p>
  
  <p>My solution contains the host app (wpf app set as startup project) and the plugin as another project (class library).
  The plugin project references the host app.</p>
  
  <p>My problem is that since the host app doesn't reference the plugin project, the plugin project is not built when I click "Start" and I need to manually build it each time I modify it before I start the host app.</p>
  
  <p>In the "Project dependencies" of my solution, I cannot add my plugin project to the dependencies of my host app since VS says it would create a circular reference (it wouldn't since my host app doesn't really need the plugin to compile or work).</p>
  
  <p>Is there a way to tell VS I want the plugin project built when I click Start (if the plugin project is out of date), even if it's not a real reference ?</p>
  
  <p>Thanks,
  Regards.</p>
