+@rem We can't do just "nuget restore" because restoring a .sln solution doesn't work
+@rem with nuget 3.X. On the other hand, we need nuget 2.12+ to be able to restore
+@rem some of the packages (e.g. System.Interactive.Async), but nuget 2.12
+@rem hasn't been officially released.
+@rem Please note that "Restore nuget packages" in VS2013 and VS2015 GUI works as usual.
