As long as there’s a programmatic way to access data on the site, REST or not, you can create a front-end for it. Also, it’s probably not really RESTful.
the app speak for itself before trying to think of ways to make money off it. And whatever you do, provide a way for people to try before they buy or offer in-app upgrades.

client class Create a repository to manage working with the API client and any local storage solutions Register the two services with Caliburn Inject and consume the repository in your view models
response content, we’ll throw. Then, we deserialize the response content (using JSON.NET in this case) and returning the expected type. Gotcha: “Root Element” Example response from server { "legislator": { "first_name": "Kamran", "last_name": "Ayub" } }
own services Your repository and client can be PerRequest but I’ve used Singleton for my app. Since the main page is a Panorama, I’ve also made that a Singleton as well. SettingsModel is used to store cacheable settings, so that’s a Singleton.
ctor In addition, you can inject other view models as well, either as an instance public MyRepsViewModel(SettingsModel settings) or a factory that generates new instances: public MyRepsViewModel(Func<SettingsModel> settingsFactory)
and storage. Expose public observable properties Due to differences in the API for WP7/WP8, you might need to use compile constants. LongListSelector differs for each platform.
Set up any fake data you want in the ctor. Use Caliburn’s InDesignMode to determine whether or not to set up your mocked data. You will see your fake data populated in the design-time view in Visual Studio, making it way easier to design! Design-Time Binding
etc.) Avoid using event messaging for internal events (single VM) Be cognizant of other events triggering your events and plan accordingly Don’t modify the message contents (keep it immutable) Order of subscribers shouldn’t matter

easily using extension methods In a POST-Redirect-GET pattern, it works a little differently in a native app environment but the same logic applies. Redirect then raise a message:
