title: No pdb generated in Visual Studio 2015
body: <p>I've got a solution that works fine when I open it in VS2013 (Ultimate), but when I open it in VS2015 (Enterprise), two of the projects don't generate debug information. </p>
  
  <p>One project is an MVC 5 app and the other is a class library. All projects in the solution are set to .net 4.5 and all are set to debug mode</p>
  
  <p>The advanced settings for both projects are set to full and appear to compile without issue, yet when I open the Debug > Windows > Modules window while the site is running, these two binaries have "Binary was not built with debug information" in their Symbol Status (every other binary in the solution loads symbols correctly)</p>
  
  <p>I've deleted the bin/obj folders, cleared temporary asp.net files, restarted both VS and windows(10) and no luck</p>
  
  <p>This is affecting other team members, so it doesn't appear to be an issue with my environment</p>
  
  <p>Also, if I compile in VS2013, VS2015 will use the pdb's without problem, it just won't generate them for itself</p>
  
  <p>I'm assuming this is a setting/feature/bug somewhere in VS2015, but i'm not sure what else I can check/change to get this sorted out</p>
  
  <p>EDIT: The web project has it's web.config set to debug="true" and it isn't being affected by config transforms</p>
