Initial commit of refactor of better/more efficient in terms of mem and performance properpty selectors for our models, this also yields a much cleaner syntax. I have discovered one issue now which is that the PropertyChanged event now fires before the property value is actually set, this is why the lambda syntax existed before. Instead we can use a ref property for the SetPropertyValueAndDetectChanges methods which will work much nicer - and also potentially have less allocations.
