This is a forever work in progress Xamarin.Forms Android project which is intended to feature most of the new features that makes the upcoming Microsoft Surface Duo phone unique. It will use the awesome German Dr. Windows as data source for its articles.

This is neither an offical Dr. Windows app nor anything other than a highly motivated playground to dive deep into the Xamarin.Forms ecosystem with a dedicated usecase in mind.

It will target only Android devices and it's meant to include all other aspecs of Xamarin development such as a configurared continuous integration and analytics powerd by the Azure App Center.

This project is written and owned by a beginner and meant for beginners. It would be perfect if experts could mentor the project - but this is just a mind in the clouds.

If you are looking for the siblings app that's based on the UWP ecosystem to work with the Surface Neo, please see the GitHub repository tscholze/uwp-road-to-surface-neo. This project is currently on hold due to some emulator requirements that I cannot fulfill at the ment.

• Windows 10 / macOS
• Visual Studio 2019 (for Mac)
• Installed Xamarin Visual Studio plugins

• The Surface Duo will usw two navigation pages, master on the left screen and detail on the right, as the main indicator how to display an app on two screens -> Nope it works a little bit diffrent

• Microsoft OneNote as information storage around the idea of the app
• Microsoft Teams to clarify open question with the Dr. Windows team
• Visual Studio Code for all, except source code editing, writings like mark down files
• Git Bash for Git operations outside of Visual Studio
• Adobe XD to protoyp the UI

• Good looking, hopefully (in my opinion)
• Utilizes Surface Duo features
• Utilizes App Center features
• Ticker with latest tweets of @drwindows_de
• Lists articles of Dr. Windows
• Lists videos of Dr. Windows Youtube Channel
• Detail article view
• Share functionality

I'm not a skilled user interface designer nor I have an eye for beauty, but the app should look mostly like the following concepts.

Running on a Microsoft Surface Duo

I used the free, but required an Adobe ID, application Adobe XD to create the protoyp views.

• Using the Page.Navigation(...) feature instead of the new url-based Shell.GoToAsync(...)
• Using the native asset management instead of the embedded images one. The not successful feature implementation can be found via: deadend/embedded-images
• No more gradients - updated UI of the app to use solid colors instead of blue-ish gradients

This app is purely build for having fun! All features have room for improvements or could be done more elegant. This app was and will be never meant to run in production-like environments.

Feel free to improve the quality of the code. It would be great to learn more from experienced C#, Xamarin and Azure developers. Please use the "default" workflow of contributing to this project.

1. Open an issue and describing your idea or bug finding
2. Fork repository
3. Fix bug / add enhancement in well named feature branch with issue number (e.g. user.name/2-added-app-icon)
4. Add the issue number to your commit message (e.g. #2 Added new app icon)
5. Create pull request (PR) from your feature branch to this master branch
6. Please keep in touch with your PR to answer upcoming questions
7. If your PR got merged, check if you are listed in the "Authors" section of the readme
