Xamarin RFID Nuget packages

Hello all,

I'm developing an Android (Xamarin) application with RFID for RFD2000, RFD8500, MC3300R etc etc. I'm following the developer guide (https://www.zebra.com/content/dam/zebra_new_ia/en-us/manuals/mobile-computers/rfid-sdk-for-android-dg-en.pdf ) and I wonder why there isn't a Nuget Packages instead of DLL.

Thank you for your time in advance,

Filippo
