Step 3 Using Infragistics controls
Next, you will add the Infragistics controls to the solution. Right-click on the project, and then click Manage NuGet Packages for Solution. Change the package source to Infragistics (Local). On the Browse tab, select the Infragistrics.XF.Gauges package. Specify the package for the Android app and then add the package.
After the package has been added to the solution, the Infragistics Toolbox will be updated with the Xamarin.Forms controls. These are additional components that you can drag and drop to create fully configured XAML code without having to write any.
Another feature of using the toolbox to add components is that the required namespaces for components will also be added when dragging a component onto the XAML screen. For example, if you drag and drop the XamRadialGauge control, not only will the gauge XAML populate, the Infragistics namespace will also be created in the ContentPage element.
The necessary namespace will be automatically created based on the control that you drag and drop. Add the XamPieChart control to the XAML to see the changes in the namespace.
