  • 11. Windows 8.1 & Windows Phone 8 Sharing technique Separate UI and app logic using the Model-ViewViewModel pattern Share functionality using Portable Class Libraries Share code with Add as Link Share using Windows Runtime Components Sharing XAML UI Conditional compilation with preprocessor directives When to use This guidance is applicable to many app types, but particularly to apps that have a XAML UI. Separation allows you to write the app logic and to concentrate on user experience design separately. An added benefit is that your app logic is more likely to be common for your app on both platforms, and therefore is a great candidate for code sharing using the rest of the techniques described here. Model-View-ViewModel (MVVM) is a great way to achieve this separation. Windows Phone 8 and Windows 8 share the same .NET Framework engine. In a XAML app, most of your app logic will be written in managed code. If you are using the MVVM design pattern, you have the potential to share your viewmodel and potentially your model. Note that Portable Class Libraries are a .NET Framework concept and don’t support C++. Use this technique for code that is non-portable and therefore can’t be implemented in a Portable Class Library. For example, Windows Phone 8 and Windows 8 can use the common Windows Runtime API surface to harness the power of each platform for networking, proximity, in-app purchase, and many other features. Portable Class Libraries don’t support Windows Runtime API. Instead, you can abstract this non-portable code, which is common to both platforms, into a class that can be shared using Add as Link in Visual Studio. In C++ projects files are added to projects as linked files by default. In addition to consuming the common Windows Runtime API available on both platforms, you can write your own Windows Runtime Component to make your functionality available in all supported languages. This can be written in C++ and consumed by C# or VB. This is a very useful technique for language interoperability or for when you want to write compute-intensive code in C++ and use it in all languages. The UI in Windows Phone 8 and Windows 8 is written in XAML. However, the XAML implementations are not portable between the platforms. But you can isolate some of your custom basic UI building blocks into UserControls and share those classes as linked files that will be compiled for each platform. This technique is limited and should be used only for simple, reusable parts of your UI. The core of your UI should be built and tailored separately for each platform. If you have functionality that’s implemented differently for Windows Phone 8 and Windows 8, you can use conditional compilation to compile the code suitably for each platform. You can’t use conditional compilation in a Portable Class Library.

  • 16. Windows 8.1 & Windows Phone 8 But today we will not talk about responsive or cross device development or pattern’s, just want that you keep in mind that there are diferences and even if we want a ap for wp and windowa we can still use HTML 5 in Windows. Becouse even using xaml we may not have/want a total app reuse.
  • 17. Windows 8.1 With HTML “It also means that you’ll be able to leverage existing investments in JavaScript libraries and CSS template repositories: writing a native app doesn’t force you to switch frameworks or engage in expensive porting work. That said, it is also possible to use multiple languages to write an app, leveraging the dynamic nature of JavaScript for app logic while leveraging languages like C# and C++ for more computationally intensive tasks” Kraig Brockschmidt
