title: How to make WPF projects build on run?
body: <p>In Visual Studio 2012 I want my projects to build on run. Typically I'd do this via </p>
  
  <p>Options> Projects and Solutions > Build and Run > Always build when project is out of date.</p>
  
  <p>For all my other solutions Winforms, MVC, class libraries, etc this happens but not with WPF projects.
  How can I make this the default behaviour in WPF?</p>
