Shiny.Contacts.Extensions.AI 5.2.1

Shiny Client for .NET

<img src="https://github.com/shinyorg/shiny/raw/master/art/logo.png" width="100" />

Shiny is a cross-platform framework designed to make working with device services and background processes easy, testable, and consistent while bringing things like dependency injection & logging in a structured way to your code!

Features

• Handles all of the cruft like Permissions, main thread traversal, persistent storage and app restarts
• Brings your infrastructure to the background
• Provides logging to ensure you know when your services fail in the background
• Gives a clean & testable API surface for your code
• Native AOT & trim-friendly across all modules
• Cross-platform: iOS, Android, Mac Catalyst, macOS, Windows, Linux, and Blazor WebAssembly (where the platform allows)

Modules

• Background Jobs - periodic background work backed by BGTaskScheduler (iOS), WorkManager (Android), COM-activated background tasks (Windows), and an in-process managed runner for Linux/macOS/Blazor WASM
• HTTP Transfers - resumable background uploads/downloads on NSURLSession (iOS), an HttpClient-driven managed loop with Range-based resume (Android, Windows, Linux, macOS, .NET base), and Service Worker Background Sync (Blazor WASM). Pause/resume support - pause stops a transfer without cancelling it (downloads continue from where they left off, uploads restart). First-class Azure Blob Storage and AWS S3 (SigV4) request builders included
• Data Sync - bidirectional JSON record sync over HTTP with the same platform tiers as HTTP Transfers: outbox + inbox on NSURLSession (iOS/Mac Catalyst), Foreground Service + HttpClient (Android), HttpClient + connectivity loop (Windows/Linux/macOS), and LocalStorage-backed HttpClient (Blazor WASM). Includes batched outbox, tombstones, conflict resolution, retry with exponential backoff, and AOT-safe serialization through Shiny.Json
• BluetoothLE Client - scan, connect, GATT, and L2CAP CoC on iOS/macOS, Android, Windows, Linux (BlueZ), and Blazor WebAssembly (Web Bluetooth)
• BluetoothLE Hosting - GATT server, advertising, iBeacon broadcasting, and L2CAP CoC listeners on iOS/macOS, Android, Windows, and Linux (BlueZ AF_BLUETOOTH sockets)
• Locations - foreground/background GPS, geofence monitoring, and motion-activity recognition (CMMotionActivity / ActivityRecognition)
• Contacts - cross-platform device contact access with CRUD and LINQ queries (iOS/Android)
• Local Notifications - scheduled, repeating, and geofence-triggered notifications on iOS/macOS, Android, Windows, and Linux (org.freedesktop.Notifications D-Bus)
• Push Notifications - native APNs/FCM, Firebase Cloud Messaging, Azure Notification Hubs, and Blazor (Web Push)
• Core - hosting, DI, key/value stores, object-store binding, lifecycle hooks, connectivity & battery monitoring, and the platform abstractions every Shiny module builds on

AI Tools

Optional *.Extensions.AI packages expose Shiny modules as Microsoft.Extensions.AI tool functions (AIFunctions) for LLM agents. You opt-in exactly which operations the model can see - a read/write allow-list you control on behalf of the agent (this is not an OS permission prompt; the underlying platform permissions must already be granted). Resolve the generated *AITools bundle from DI and pass .Tools to any IChatClient. All are AOT-compatible (hand-built schemas, no reflection).

• Shiny.Contacts.Extensions.AI - AddContactsAITools(...) → search_contacts, get_contact, and (write) create_contact, update_contact, delete_contact
• Shiny.Notifications.Extensions.AI - AddNotificationAITools(...) → reminder-framed list_reminders, and (write) create_reminder (one-time or daily), cancel_reminder
• Shiny.Locations.Extensions.AI - AddLocationAITool() → read-only get_current_location, get_distance_to, estimate_travel_time

builder.Services.AddContactStore();
builder.Services.AddContactsAITools(b => b.AddContacts(ContactAICapabilities.ReadWrite));

builder.Services.AddNotifications();
builder.Services.AddNotificationAITools(b => b.AddReminders(ReminderAICapabilities.ReadWrite));

builder.Services.AddGps();
builder.Services.AddLocationAITool();

// later, hand the tools to a chat client
var tools = sp.GetRequiredService<ContactAITools>().Tools;
var response = await chatClient.GetResponseAsync(messages, new ChatOptions { Tools = [.. tools] });
