SearchView query binding not working on mvvmcross 7.0
after updating my project mvvmcross 7.0 my searchView not works on, i tried to change searchView namespace with AndroidX, but with 7.0 either android.support.v7.widget.seearchView or androidx.appcompat.widget.searchView are not working.

This is output message and i cant solve this, i think it is about upgrading mvvmcross.
**(MvxBind) Failed to create target binding for binding Query for SearchString**
