title: Visual Studio 2013 Set as start up project does not change the project
body: <p>I have several projects in the solution. When I set the "Set as start up project" (In VS 2013) to the Console application project and when I hit F5, it sets the start up project to a particular class library project (Class Library 1). I cannot change the start up project from "Class Library 1" to anything else. I tried to change the start up project by right clicking the project as well as right clicking the solution and then set the start up project from there.</p>
  
  <p>When I set the start up project as the "Console App1" project, it indicates that it has been selected properly (bold the project name). But once I hit F5, it tries to execute "Class Library 1" (bold the Class Library project) and gives an error (A project with Output Type of Class Library cannot be started directly). </p>
  
  <p>I tried to delete the .suo file and open up the solution, still I am getting the issue. 
  Where is the start up project details are stored? Could not find any clue inside the sln file as well. Any ideas? </p>
