I've inherited a Xamarin Android app, and I'm not fully familiar with the way it works. For a class I'm creating, I want to use the packages Android.Content and System.Environment, however neither are available (when I start typing they don't show up in the code completion dropdown).
I'm wondering what determines the available packages for an application, and how to make more available?
Okay it took me a while to find this information, even though it's probably common knowledge.
To add packages, in Xamarin, right-click on the "References" directory under your project and select "Manage References". Then from this dialog, select whatever package that you need to add.
