Not Required.It's needed in the earlier version of visual studio not need now as described in the Article

The Visual Studio SDK provides a Developer Load Key (DLK) that makes it possible for VSPackages to load without a PLK during development

And if we still need the PLK then it will be generated from this website http://msdn.microsoft.com/en-us/vstudio/cc655795
