Architecture

This page defines the architectural patterns and layering used in the GregCore Modmanager.

Current State

• GregCore Modmanager is the Avalonia UI-based desktop application.
• It targets .NET 9 for optimal performance and cross-platform compatibility.

Layering

The project follows a strict 4-layer separation:

1. Presentation: Avalonia UI and ViewModels.
2. Domain: Business logic and interfaces.
3. Infrastructure: Steam API, Telemetry, and Persistence.
4. Extensions: MelonLoader plugins (.NET 6).

Migration Strategy

1. Keep MAUI app functional while introducing Avalonia in parallel.
2. Move reusable business logic from MAUI-only concerns into shared services.
3. Replace page-by-page UI workflows in Avalonia.
4. Transition packaging and release channels to multi-platform outputs.

Design Constraints

• Compact information density for usability.
• Keyboard-first interaction patterns.
• Strict Steam publish cooldown enforcement.
• Fully custom window chrome to avoid duplicate title bars.
