Xamarin Component Review Guidelines
- PDF for offline use
Let us know how you feel about this
The Component Store was launched in March 2013, as part of the Xamarin 2.0 launch, with the aim of helping developers get their apps built faster and to add great features without a lot of work. The store has a catalog of stunning UI controls, charts and graphs, beautiful themes, cloud services, and other powerful features that you can add to your app in minutes. The Component Store is integrated into both Xamarin Studio and Visual Studio so that components can be added to your app with just a few clicks. This document provides the rules and requirements that your component should comply with to ensure it is reviewed and approved as quickly as possible..
We opened the Xamarin component store in March 2013 as part of our Xamarin 2.0 launch. The component store allows talented developers to package and publish their code for other developers to integrate into their own projects improving the entire Xamarin ecosystem and making it an even better place to develop your mobile apps.
We have published these component review guidelines so that you can see how we review your components and what we are looking for. By reading them you can improve the speed of review and increase your chances of getting approved first time.
