5. Use lambda expression • [] : lambda-capture • () : argument • {} : function - source code • () : call function #include "stdafx.h" #include <string> #include <iostream> int_tmain(intargc, _TCHAR* argv[]) { [ ]( std::string const &str ) // argument { std::cout << str << std::endl; } // define function ( “Hello World!“ ); // call function return 0; } Use lambda to PPL task, STL and so on

6. Use smart pointers

7. Automatic type deduction Use return value auto decoder = make_shared<BitmapDecoder^>(nullptr); And Use data collection for (auto file : files) { auto photo = ref new Photo(file, ……); }

8. Be aware of overhead for type conversion ref class via Platform/Windows namespace For exsample You useas a Windows::Foundation::Collections::Vector^ std::vector vector<AAA^> vec_a; b= ref new Vector<AAA^>(std::move( vec_a )); for move semantics

9. to understand your app's .winmd output ref class -> on the premise of public ->.winmd that contains metadata for all thepublicreftypes -> beyond the ABI permeter! Don’t expose to unnecessary class To use the ref class for cross-language interop
