How & where C++ is supported

When and why to use C++

Introduction to the Windows (Phone) Runtime

Sharing C++ code (demo)

agenda

how: windows phone C++ support

Can be used in any Windows Phone App

Visual Studio Express 2012/3 for Windows Phone

Visual Studio 2015 Community Edition

Same C++ compiler & CRT used in Windows 8 / 10

Subset of C++ 11 standard features

sampling of C++ 11 standard features

RValue references Forward declared enums Bidirectional fences

static_assert Alignment Data-dependency ordering

Auto Standard-layout and trivial types exception_ptr

Trailing return types Extended friend declarations Thread-local storage

Lambdas Local and unnamed types as template arguments __func__

Decltype Range-based for-loop C99 preprocessor

Right angle brackets override and final long long

extern templates Minimal GC support Strongly typed enums

nullptr Atomics

C++11 Features in Visual C++ 11

Announcing the Visual C++ Compiler November 2013

why use C++

Reusability: You have some legacy code around that you really don't want to rewrite but still use in your app

Portability: You want to use the code you're about to write on multiple platforms

Performance: You really are in need for these last bits of performance benefits and know what you're doing

Personal Preference: You are a developer who really favors C++ over e.g. C# or you have significantly better skills in C++

where you can use C++

All Windows Phone 8 / 10 apps can use native code…XAML apps (8.1)XAML apps mixed with D3D and WinRTPure native D3D apps/gamesC++ libraries: Dynamic Link Libraries, Static LibsWinRT C++ Components

Access to SD Cards

Geofencing

App to App sharing

And much more…

windows (phone) runtime

Why learn about WinRT?WinRT is used in the application model

C++ code called from XAML uses WinRT

Phone Platform APIs are built using WinRT
