title: WinForm application doesn't start outside Visual Studio 2010
body: <p>I have a WinForm application written with VS2008 and .NET 3.5. This application runs well from Visual Studio 2008 and outside (when VS2008 is closed, simple double-click on the EXE boots the application). </p>
  
  <p>I decided this morning to migrate everything to VS2010 and .NET 4 (updated the target framework). Everything compiles and the application runs from VS2010 (click on the play button - in debug as well as in release). However, when I try to launch the application from explorer.exe, I see "Blabla has stopped working... Windows is checking...". </p>
  
  <p>How can I debug such issue? I cannot attach the debugger since the application is not even started.</p>
  
  <p>Thanks!</p>
