Which version of .NET is this optimized for?

While the pattern works for older versions, the provided code specifically targets .NET 7 and later, utilizing modern C# features like file-scoped namespaces and global usings.

How does this implementation handle performance?

The base classes utilize a Lazy singleton pattern, ensuring that converter instances are instantiated only when needed and reused across the application to minimize memory footprint.

Does this skill support MultiValueConverters?

Yes, the skill includes specialized base classes and implementation examples for both standard IValueConverter and IMultiValueConverter interfaces.

Why use MarkupExtension for converters instead of StaticResource?

It allows you to use converters directly in XAML (e.g., {local:MyConverter}) without needing to define them in a ResourceDictionary first, which reduces code volume and prevents resource key naming conflicts.

デザインツール

Simplifies XAML development by implementing IValueConverter as a MarkupExtension to eliminate redundant resource dictionary declarations.

概要

This skill provides a streamlined pattern for WPF and .NET developers to implement IValueConverters and IMultiValueConverters directly within XAML attributes using MarkupExtensions. By bypassing the traditional StaticResource declaration requirement in resource dictionaries, it significantly reduces boilerplate code, minimizes XAML clutter, and leverages a built-in lazy singleton pattern. It is ideal for teams looking to standardize UI logic and improve the maintainability of complex desktop application interfaces.
