3. How to program? Windows Store Apps for C++/CX

4. OS process Dev Env WindowsStoreApps(UI XAML) http://msdn.microsoft.com/ja-jp/library/windows/apps/jj160326.aspx http://msdn.microsoft.com/ja-jp/library/windows/apps/jj160326.aspx Windows Kernel Services Windows RuntimeWin32 and COM CRT STLPPL App container ( package manifest ) UI controls ( XAML ) App-defined ref classes for cross- language interop Implimentation class (C++ native) VS Project Template C++/CX Do not mix. Hazardous.

5. Use lambda expression #include "stdafx.h" #include 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

6. Use smart pointers 変数名 Windows Runtime variable ^ (hat) COM cariable Microsoft::WRL::ComPtr the others std::shared_ptr / std::unique_ptr

7. Automatic type deduction Use return value auto decoder = make_shared (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 use as a Windows::Foundation::Collections::Vector^ std::vector vector vec_a; b = ref new Vector (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 the public ref types -> beyond the ABI permeter! Don’t expose to unnecessary class To use the ref class for cross-language interop
