title: VS2010SP1: Project always out of date when debugging
body: <p>I experienced this problem in VS2010 before, and solved it looking at this <a href="https://stackoverflow.com/questions/2762930/vs2010-always-thinks-project-is-out-of-date-but-nothing-has-changed">SO question</a>. However, now that I upgraded my VS to SP1, it appeared again. I tried to solve it the same way, enabling C++ projects logging and using <a href="http://technet.microsoft.com/en-us/sysinternals/bb896647" rel="nofollow noreferrer">DebugView</a>. But I can't get to see any output in DebugView, no matter what I do. I also tried raising the Build output verbosity (Tools->Options->Projects and Solutions->Build And Run), but couldn't find any clue.</p>
  
  <p>As in the original problem, the projects reported as out of date are always unmanaged C++ projects. The solution has C#, VB.NET, C++/CLI and C++ projects. What I'm trying to run is a VB.NET exe which uses some C++ projects through C++/CLI wrappers.</p>
  
  <p>Any hint on how to troubleshoot this?</p>
  
  <p><strong>UPDATE</strong>: Solved it with a clean checkout. However, it's a shame that there is no longer a way to troubleshoot this kind of errors...</p>
