out of range exception but index is in range! wp 7.1
===

Ever since I converted my project from the 7.0 to 7.1, I have been getting really weird errors.  for instance:

  

    List<bool> locks = new List<bool>(11);
    locks[0] = true;

it throws an argument out of range exception on the second line, but when i put my mouse on locks it shows it has 11 elements all of which are initialized to false.
