title: Visual Studio won't make debug DLL
body: <p>Visual Studio won't make a debug DLL when I select Debug for the configuration.</p>
  
  <p>Instead it makes a release version.  The output window show it's making a release version, even with a Debug configuration selected.  The release DLL it produces has the current date.</p>
  
  <p>When I save the project in the Debug configuration and reload it, it has magically switched to the Release configuration.</p>
  
  <p>The project has been behaving for months, and this problem just started happening today.</p>
  
  <p>What's going on, and how can I make it produce a debug DLL?</p>
