Today marks the initial release of Mobilize.NET’s Silverlight bridge, which helps Windows Phone Silverlight app developers bring their WP Silverlight 8.x apps to the Windows 10 Universal Windows Platform (UWP). Announced at Build 2015, the Moblize.NET bridge is free and directly integrates into Visual Studio. The bridge currently maps the 700 most used APIs and handles transitioning your manifests, APIs, XAML, NuGet package references and async/await changes. More APIs and mappings will follow with future updates. Mobilize.NET has a much more in-depth post on the Silverlight bridge that goes into detail on the features, so here we share only a high-level overview of the tool.
Once you use the tool to bring your app to the UWP, your app will have all the power of a UWP app, including the ability to – from a single code base – run on a PC, phone, Xbox, HoloLens, or even a Raspberry Pi.
Running the bridge
Once installed, open up Visual Studio, load your WP Silverlight app, then right-click your project from the Solution Explorer and select the “Convert to UWP” option. Additionally, any project that is in the solution will be migrated.
Helping extend and improve the mappings
The Silverlight bridge does the migration with a feature named the Mapping Mechanism. All mappings bundled with the tool have been open sourced and published in a public GitHub repository (https://github.com/MobilizeNet/UWPConversionMappings). This way developers around the world can use them as a reference implementation to write their own.
The Silverlight bridge may not do a full transition as this is an initial preview now but the tool should get you most of the way. Since Silverlight is similar to UWP but not the same so most errors should be pretty straightforward to resolve. Once you fix compiler errors, you should be ready to start testing and adjusting your app.
The Building apps for Windows 10×10 article series has some helpful guidance on building apps. Topics range from building responsive UIs, speech, live tiles, to how to help get your app promoted in the Store.
