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

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 RuntimeWhy 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
