title: Visual Studio: How to build only some projects
body: <p>My VS solution has many projects.
  I am currently only working on some of them so I want CTRL+SHIFT+B to only build some.
  What's the best way to do it?</p>
  
  <p>I thought about creating a new configuration but I would need to check it in and it does not seem right. I don't care if it will be only a "local" setting on my machine.</p>
