Why is [ObservableProperty] required to be inline?

The skill enforces inline placement to maintain code density and provide a consistent visual style that differentiates simple properties from multi-attribute declarations.

Does this support command implementation?

Yes, it includes patterns for RelayCommand and NotifyCanExecuteChangedFor to handle both synchronous and asynchronous UI actions.

How does this skill handle MVVM boilerplate?

It utilizes CommunityToolkit.Mvvm source generators to automatically generate backing fields and RaisePropertyChanged logic from simple field attributes.

Which .NET versions is this compatible with?

It is designed for modern .NET (Core/5+) environments that support the latest CommunityToolkit.Mvvm features and C# source generators.

Developer Tools

Implements the MVVM pattern in WPF applications using CommunityToolkit.Mvvm and C# source generators for clean, boilerplate-free code.

About

This skill provides standardized guidelines and implementation patterns for building robust WPF applications with the CommunityToolkit.Mvvm library. It focuses on leveraging modern C# source generators via the ObservableProperty attribute to eliminate manual property change notifications and command boilerplate. By enforcing specific attribute placement rules—such as keeping ObservableProperty inline—it ensures high code readability and consistency across ViewModel implementations, helping developers transition from legacy MVVM approaches to modern, attribute-driven development.

Key Features

Standardized attribute placement for improved code readability
