title: convert int to wstring
body: <p>I want to convert an integer value (int) to std::wstring. What is the best way to do this? I'm developing for windows phone so I would rather avoid using external libraries (such as boost::lexical_cast). I'm looking for something simple, preferably one line of code that just assigns the int to the wstring.</p>
  
  <p>Any help would be appreciated.</p>
