I've decided against using the JSON approach since the model conversion is so basic as to be worthless in a real application. You essentially have to have a JSON file that maps precisely to the model with no exceptions which requires a very trivial model. I'm going back to XAML :(
How do I use Data Binding with XAML Apps, MVVM & JSON Sample Data?

The Universal App template has sample data in JSON and a SampleDataSource that loads that JSON file and provides a model. This is nice but I'm using MVVM and I need the PropertyChange Notifications.
My aim is this
DesignTime
- Load Sample Data from a json file (my webservice provides data in JSON so this is super helpful)
- Display the sample data in my UI
RunTime
- Load JSON (well PBF really) data from my live webservice
- Display Real Data in my UI
I'm struggling to understand how the databinding is meant to work in design time.
Should I have code to load and process the JSON into a model?
My JSON converts into my DataModel not my ViewModel, is this supported in the SampleData infrastructure?
