This package is deprecated moving forward. A new package has been uploaded that is no longer a C# port of the library, but a direct binding of the Java code:
Xamarin.Google.Android.Vending.Expansion.Downloader

There are several breaking changes, although the API is fairly similar - mostly namespace/type changes. All the changes are documented here, along with their replacements:
