# Application Services

The project relies heavily on dependency injection to provide specialized services. These are split into game-logic services (`Immortal`) and infrastructure services (`Website`).

## Game Logic Services (`Services.Immortal`)

- **IBuildOrderService (`BuildOrderService`)**: Manages build order creation, editing, and calculations.
- **IEconomyService (`EconomyService`)**: Handles calculations related to resource generation and expenditure.
- **IEconomyComparisonService (`EconomyComparisonService`)**: Compares different economic scenarios.
- **IEntityFilterService (`EntityFilterService`)**: Provides logic for filtering game entities based on various criteria.
- **IImmortalSelectionService (`ImmortalSelectionService`)**: Manages the current selection of the "Immortal" (faction/hero).
- **ITimingService (`TimingService`)**: Calculates timings for unit production and upgrades.
- **IMemoryTesterService (`MemoryTesterService`)**: Supports the memory tester mini-game.

## Infrastructure Services (`Services.Website`)

- **IStorageService (`StorageService`)**: Wraps LocalStorage to provide persistent state management for the application.
- **INavigationService (`NavigationService`)**: Manages application-level navigation and state.
- **ISearchService (`SearchService`)**: Powers the global search functionality.
- **IEntityDialogService (`EntityDialogService`)**: Controls the display of unit/building detail dialogs via portals.
- **IMyDialogService (`MyDialogService`)**: A wrapper around MudBlazor's dialog service for simplified use.
- **IToastService (`ToastService`)**: Provides a unified way to show notifications (toasts).
- **IDataCollectionService (`DataCollectionService`)**: Handles anonymous usage analytics.
- **IPermissionService (`PermissionService`)**: Manages user permissions or experimental feature toggles.

## Service Registration

All services are registered in `Program.cs`. Example:
```csharp
builder.Services.AddScoped<IBuildOrderService, BuildOrderService>();
builder.Services.AddScoped<IStorageService, StorageService>();
```
In Blazor WebAssembly, `AddScoped` effectively acts as a singleton for the session.
