Consuming and Creating Xamarin.Forms Plugins

There are many native platform features that exist across all platforms but have slightly different APIs. One way for developers to use these features is by creating an abstract cross-platform interface, and then implementing that interface in the various platforms. The Xamarin.Forms application then accesses these platform implementations using DependencyService.

Developers can share this work by writing a plugin and publishing it to NuGet.


Many cross-platform features previously available only through plugins are now part of the open-source Xamarin.Essentials library. These features include: battery status, compass, motion sensors, geolocation, text-to-speech, and a lot more. In the future, Xamarin.Essentials will be the primary source of cross-platform features for Xamarin.Forms applications. Although developers can still create and publish plugins, consider contributing to Xamarin.Essentials.

Finding and Adding Plugins

The Xamarin community has created many cross-platform plugins compatible with Xamarin.Forms. A large collection can be found at:

Xamarin Plugins

Creating plugins

It's also possible to create and publish your own plugins as Nuget packages (and Xamarin Components). Many existing plugins are open-source so you can review their code to understand how they have been writtern.

For example, the list of plugins below are all open source, and they correspond to some samples in the DependencyService section:

  • Text-to-Speech by James Montemagno – GitHub and NuGet
  • Battery Status by James Montemagno – GitHub and NuGet

Those Github projects can provide a good starting point for creating your own cross-platform plugins, as do these instructions for creating a plugin for Xamarin.

Structuring Cross-Platform Plugin Projects

Although there are no particular requirements for designing a NuGet package, there are some guidelines for creating a package for cross-platform apps.

In the past, a cross-platform plugin generally consisted of the following components:

  • PCL with an Interface that represents the API for the plugin,
  • iOS, Android, and Universal Windows Platform (UWP) class libraries with an implementation of the Interface.

Read James Montemagno's blog post describing the process of creating plugins for Xamarin.

More recently, plugins can be be created with a single multi-targeted platform. This approach is discussed in James Montemagno's blog post. This approach is used in James Montemagno's plugins linked above, and is also the format used in Xamarin.Essentials.

It is a preferable to avoid referencing Xamarin.Forms directly from a plug-in. This can create version-conflict issues when other developers attempt to use the plug-in. Instead try to design the API so that it can be used by any Xamarin or .NET application.

Publishing NuGet Packages

NuGet packages have a nuspec file, which is an xml file that defines which parts of your project are published in the package. The nuspec file also includes information about the package, such as id, title, and authors.

See NuGet's documentation for more information about creating and publishing NuGet packages.
