Avalonia Zafiro Development
This skill defines the mandatory conventions and behavioral rules for developing cross-platform applications with Avalonia UI and the Zafiro toolkit. These rules prioritize maintainability, correctness, and a functional-reactive approach.
Core Pillars Functional-Reactive MVVM: Pure MVVM logic using DynamicData and ReactiveUI. Safety & Predictability: Explicit error handling with Result types and avoidance of exceptions for flow control. Cross-Platform Excellence: Strictly Avalonia-independent ViewModels and composition-over-inheritance. Zafiro First: Leverage existing Zafiro abstractions and helpers to avoid redundancy. Guides Core Technical Skills & Architecture: Fundamental skills and architectural principles. Naming & Coding Standards: Rules for naming, fields, and error handling. Avalonia, Zafiro & Reactive Rules: Specific guidelines for UI, Zafiro integration, and DynamicData pipelines. Zafiro Shortcuts: Concise mappings for common Rx/Zafiro operations. Common Patterns: Advanced patterns like RefreshableCollection and Validation. Procedure Before Writing Code Search First: Search the codebase for similar implementations or existing Zafiro helpers. Reusable Extensions: If a helper is missing, propose a new reusable extension method instead of inlining complex logic. Reactive Pipelines: Ensure DynamicData operators are used instead of plain Rx where applicable.
