Road to Surface Duo Xamarin App (#rTsd)

This is a 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.

Build status

Service Status
AppCenter Badge



Xamarin.Forms container that includes all shared functionality and features.


Android wrapper and platform-specifc implementations like custom rendereres, effects or assets.


  • Finding a usecase
  • Write down a motivation (e.g. Readme)
  • Write an email to to get soon(tm) more information
  • Concept roughly an user interface
  • Get the project (template) up and running
  • Getting into important Xamarin / C# pattern
  • Write first MVP code
  • Write tests
  • Leverage CI with tests and test deployment




  • 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

Other programms I used

  • 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


  • Lists articles of Dr. Windows
  • Good looking, hopefully (in my opinion)
  • Utilizes Surface Duo features
  • Utilizes App Center features

UI concepts

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.

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

Keep in mind

This app is purely build for having fun! All features have room for improvements or could be done more elegant.
