You can access all the material of the Pharo Mooc at http://mooc.pharo.org
If you can something in C# you should be able to do it in Pharo simply too.
I do not understand your City<-District notation but if it means that
a city has many districts
here is the way we express it in Pharo
Object subclass: #City
instanceVariableNames: 'districts'
City >> initialize
super initialize.
districts := OrderedCollection new.
City >> addDistrict: aDistrict
districts add: aDistrict
Object subclass: #District
instanceVariableNames: '...'
You may want to read my latest book on Understanding OOP in Pharo
available at http://books.pharo.org
Good luck
