We have a native c++ class that is serialized perfectly using * boost::serialization*. Now we want to change some of its member fields to *property*, so we could use them in *PropertyGrids*. When we changed the class definiction to *ref class X*, we got a huge number of these compilation errors: #1: error C2893: Failed to specialize function template 'boost::archive::text_oarchive &boost::archive::detail::interface_oarchive<Archive>::operator <<(T &)' d:\someAddress\someFile.cpp 58 #2: error C2784: 'std::basic_ostream<_Elem,_Traits> &std::operator <<(std::basic_ostream<_Elem,_Traits> &,const std::_Smanip<_Arg> &)' : could not deduce template argument for 'std::basic_ostream<_Elem,_Traits> &' from 'boost::archive::text_oarchive' d:\someAddress\someFile.cpp 58 We have a lot of tiny classes here, so it would be a pain to write a wrapper for each of them! Here is the sample class we used: ref class gps_position2 { public: template<class Archive> void serialize(Archive & ar, const unsigned int version) { ar & seconds; } public: gps_position(){}; gps_position(float s) { this->seconds = s; } property float seconds; }; And here is the main test code: int main() { std::ofstream ofs("out.txt"); gps_position2 g(24.567f); // save data to archive { boost::archive::text_oarchive oa(ofs); // write class instance to archive oa << g; } // ................ return 0; } Is it even possible to use *boost::serialization* with managed classes? p.s. If we change the class usage code to this: ... gps_position2^ g = gcnew gps_position2(24.567f); ... then we get only 1 error: error C2027: use of undefined type 'boost::STATIC_ASSERTION_FAILURE<x>' D:\path\to\Boost\boostw\boost\archive\detail\check.hpp 60
