Agenda• How & where C++ is supported
• When and why to use C++
• Introduction to the Windows (Phone) Runtime
• Sharing C++ code (demo)
#CDays14 – Roma - 23, 24 e 25 Settembre 2014
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
#CDays14 – Roma - 23, 24 e 25 Settembre 2014
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
C++11 Features in Visual C++ 11

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++
#CDays14 – Roma - 23, 24 e 25 Settembre 2014
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
#CDays14 – Roma - 23, 24 e 25 Settembre 2014
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
#CDays14 – Roma - 23, 24 e 25 Settembre 2014
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…
#CDays14 – Roma - 23, 24 e 25 Settembre 2014
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++.
