Slides claim 80 percent of XAML code usable for Windows desktop, mobile apps
More evidence of Microsoft's merging of the Windows and Windows Phone lines has allegedly surfaced. Leaked images claimed to be from a Microsoft slideshow about the project appears to show it is working towards "Universal Store" apps, namely apps that use the same basic code base, but can be produced to work on both the mobile and desktop versions of Windows.
The images from the @AngelWZR Twitter account claim there would be two Visual Studio UI projects for code, both working from the same "business logic." Two AppX packages would be produced, which can be submitted to the Windows Phone Store and Windows Store for download and use by customers. A second slide for "Converged UI Controls" claims Windows and Windows Phone will share common elements, reports CNET, with developers able to reuse approximately 80 percent of XAML code between the two different versions, saving time with development.
The leaked slides come shortly after the company invited developers to use a new SDK for Windows Phone 8.1, which also showed evidence of a future product line merge.
