title: C# application doesn't run if out of build folder
body: <p>I'm having a weird problem. </p>
  
  <p>I made a C# "Windows Forms Application" project from VS2012. It has some 3rd party DLL linked. The build was fine and I had no problem to run the exe file which was right in project's build folder, ie \myproject\bin\Debug\x.exe. But if I copied out the exe to anywhere and double click the exe, it didn't run any more. I tried this on my own PC and other's PC as well. </p>
  
  <p>I am using windows 8 and .NET 4.5.</p>
  
  <p>Please shed some light to me.</p>
