Agenda• How & where C++ is supported

• When and why to use C++

• Introduction to the Windows (Phone) Runtime

• Sharing C++ code (demo)


How: Windows Phone C++ Support• Can be used in any Windows Phone App

• Visual Studio Express 2012/3 for Windows Phone

• Same C++ compiler & CRT used in Windows 8

• Subset of C++ 11 standard features


Sampling of C++ 11 Standard FeaturesRValue 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

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 apps can use native code…

XAML apps (8.1) XAML apps mixed with D3D and WinRT Pure native D3D apps/games C++ libraries: Dynamic Link Libraries, Static Libs WinRT C++ Components

• ...not all apps need to use native code

WP 7.0Silverlight

WP 7.5Silverlight

WP 8.0Silverlight

WP 8.1Silverlight

WP 8.1WinRT


Why stay on Windows Phone Silverlight?• Existing Code Investment

• Existing Install Base

• Not yet converged Camera Lenses VoIP Lock Screen Wallpaper. Clipboard API Simple Sound Effects (XNA) Run Under Lock Screen


Why Retarget to Windows Phone Silverlight 8.1?• Access to SD Cards

• Geofencing

• App to App SSO (Single Sign-On)

• 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 More Convergence Latest Tooling New Controls Future Investment

Same ECMA-335 standard as .NET Type-System Projections

CLR Projection Framework Projection


A Closer Look at What's Available

Direct3D with XAML" C++ application actually creates a C# main project and a separate Windows Runtime Component in C++.
