Ifdef parts of code (lexical_cast and local_time_input_facet) which don't have non-boost replacement code yet. Couple using declaration additions to CoreTypes.h.
Do not use any Boost stuff explicitly (f.ex. boost::shared_ptr<T> = ...). Instead include CoreTypes.h which includes using declaration for either boost::shared_ptr or std::shared_ptr and do "shared_ptr<T> = ...".
