title: Visual Studio 2015 highlighting / intellisense stops working after dependency rebuilt
body: <p>While working on two Visual Studio solutions, one of which depends on the other, if I build the dependency the other 'master' project seems to lose track of the dependency, but only as far as intellisense and syntax highlighting.</p>
  
  <p>So the master project can compile just fine but the red squigglies will tell me that any types defined in the dependency don't exist. If I close and reopen the solution (or unload and reload the project) things return to normal, until such time as I need to make a change in the dependency again.</p>
  
  <p>Has anyone encountered similar issues and if so is there a solution other than having to close and reopen Visual Studio or unload and reload the project?</p>
