Is this structure compatible with cross-platform .NET development?

Absolutely. By separating the Core logic and ViewModels into standard .NET Class Libraries, you ensure that the bulk of your code remains platform-agnostic while Avalonia handles the UI layer.

What is the benefit of the Abstractions layer in this structure?

The Abstractions layer houses interfaces and abstract classes, allowing for dependency inversion. This makes the code more modular and enables easy replacement of concrete implementations with mock objects during testing.

Does this skill support the MVVM pattern?

Yes, it specifically enforces MVVM by separating ViewModels into a dedicated .NET Class Library that remains independent of the UI framework, enhancing portability and testability.

How does it handle custom Avalonia controls?

The skill recommends using a dedicated .UI library for ControlTheme-based custom controls and an .AvaloniaLib for reusable UserControls, ensuring a clean separation between app logic and visual components.

Developer Tools

Organizes AvaloniaUI solutions using standardized naming conventions and clean architecture principles for scalable desktop applications.

About

This skill provides specialized guidance for architecting robust AvaloniaUI applications by enforcing a modular project structure. It helps developers implement the Dependency Inversion Principle through an Abstractions layer, separate business logic from the UI using the MVVM pattern, and organize reusable components and services effectively. It is particularly useful when starting new Avalonia projects or refactoring existing monoliths into a maintainable, testable multi-project solution following .NET best practices.

Key Features

Facilitates Dependency Inversion for easier unit testing and mocking
Implements industry-standard naming conventions for Avalonia projects
Sets up a layered architecture including Abstractions, Core, and ViewModels
Provides a clear project dependency hierarchy to prevent circular references
Guides the creation of decoupled AvaloniaServices and Custom Control Libraries
6 GitHub stars

Use Cases

Refactoring a single-project Avalonia app into a modular, testable architecture
Defining clear boundaries between UI-specific code and pure business logic
Scaffolding a new enterprise-grade AvaloniaUI solution from scratch
