Yammer Chat was a standalone app focused on the private messaging experience of Yammer. Originally built by Yammer as a promising experiment but for iOS only, this project offered the same feature set (and design...) to Windows Phone users.
The app was released in 2014 and ran for about a year.
Project is composed of Universal packages (reusable between phone and eventual desktop app) and Windows Phone-specific modules (with "WP").
Notable features include a dependency injection framework (see Bootstrapper.cs), tests, realtime updates, adoption of the async/await syntax and extensive use of interfaces.
A neat trick is the pattern of IProgressIndicator.Show() returning an IDisposable (implemented as an action hiding the indicator), coupled with feature code putting that call from within a using construct like so:
using (this.progressIndicator.Show())
{
await this.identityStore.LoginAsync(token);
...
} // No need to worry about forgetting to hide the progress indicator; the Show() method's IDisposable gets called automatically- Generic API service with cancellable async REST methods & domain-specific wrappers
- Plugin interfaces (serialization, file pickers, settings, ...)
- Network & app models, parsers
- Repositories (identity, users, threads, ...)
- BaseViewModel enabling databinding
- Domain-specific view models
- Screens
- Custom controls
- Platform implementations of plugin interfaces
- Standalone module responsible for the Live Tile unread count
Great app. Love it loads.
