Questions tagged [xamarin-community-toolkit]

The Xamarin Community Toolkit is a collection of Animations, Behaviors, Converters, Effects and Controls for mobile development with [xamarin-forms]. It simplifies and demonstrates common developer tasks building iOS, Android, and UWP apps with Xamarin.Forms.

The Xamarin Community Toolkit is a deep collaboration between the Xamarin community and the Xamarin team at Microsoft.

When Xamarin.Forms 5 was released, a few “experimental” features were the first to make their way to the toolkit. This includes the beloved C# UI Extensions, MediaElement, and Expander controls. There is much more to the toolkit though as the community has been contributing tons of great new controls and helpers.

One of the toolkit’s goal is to gather as many of those behaviors, converters, and effects that you keep copying from one project to another. This Toolkit wants to aggregate all of these into a single package so it will become your one-stop library that has it all.

The Toolkit will also be a place where you can find brand new controls. Some of them come from PRs to Xamarin.Forms that couldn’t be included in the main package, some our controls maintainers donating their controls, and some are just brand-new things!
