Do not mix. Hazardous.

Use lambda expression#include "stdafx.h"#include <string>#include <iostream>int _tmain(int argc, _TCHAR* argv[]){ [ ]( std::string const &str ) // argument { std::cout << str << std::endl; } // define function ( “Hello World!“ ); // call function return 0;}

[] : lambda-capture() : argument{} : function - source code() : call function

Use lambda to PPL task, STL and so on

Use smart pointers変数名

Windows Runtime variable

^ (hat)

COM cariable Microsoft::WRL::ComPtr

the others std::shared_ptr / std::unique_ptr

Automatic type deductionUse return valueauto decoder = make_shared<BitmapDecoder^>(nullptr);

And Use data collectionfor (auto file : files){ auto photo = ref new Photo(file, ……);}

Be aware of overhead for type conversionref class　 via Platform/Windows namespace

For exsample You use as a Windows::Foundation::Collections::Vector^ std::vectorvector<AAA^> vec_a;b = ref new Vector<AAA^>(std::move( vec_a ));for move semantics

to understand your app's .winmd outputref class

-> on the premise of public->.winmd that contains metadata for all the public ref types-> beyond the ABI permeter!

Don’t expose to unnecessary classTo use the ref class for cross-language interop
