title: MVC Application is extremely slow to build
body: <p>I am working on a Visual Studio MVC-4 project. It takes approximately 2 minutes to build the solution, which makes no sense. It is a small solution with 5 projects, with few (less than a few hundred) files in each project. To compare, we have a project which is 10-15 times the size of this project (Web forms), which builds in less than 3 seconds on my computer.</p>
  
  <p>I have heard we migrated from MVC2 to MVC4, and the team remembers the solution was much faster before the migration, but they can't exactly remember it.</p>
  
  <p>It is not only on my computer, but the rest of the computers on the team. I am pretty sure it is in the solution file somehow.</p>
  
  <p>We only have 1 post build event, and it has no effect to remove it.</p>
  
  <p>Any ideas about what to do?</p>
  
  <p><strong>What I have tried</strong></p>
  
  <p><em>Symbols</em>:</p>
  
  <p>I read a post here on SO, about setting symbols to run locally instead of server. I've done that:</p>

  <p><em>Enable "just my code"</em>
  Make sure only my code is debugged:</p>

  <p><em>Deleting temp folders</em></p>
  
  <p>Deleted all the different temp folders around on my computer.</p>
  
  <p><strong>Solution file</strong></p>
