This has been discussed before - http://mono-for-android.1047100.n5.nabble.com/Resources-in-Class-Library-project-td5658638.html
And it seems like this might be becoming real - atsushieno/MonoDroid.Dialog@2c7c5da
If it is, then:
This is now done for CrossUI (Dialog)
Still need to consider if it should be done for the MvxBinding xml file
Placing this 'on hold' - no urgent need to do it for the single MvxBinding.xml file
The MvxBinding Attributes already have been included in the binding library. CrossUI also include its own sources. Closing.
