For user components, a UserControl is provided

it can have layout inside and functionality focused on support 
for composite user components.

That's how GTK works. Layouts can be provided separately, anchors 
is the simplest one, boxes is the most flexible.

ViewModel (MVVM), while View will remain single-threaded.
