Will this help me move away from Xamarin.Forms?

Absolutely. It contains specific rules to prevent the generation of 'using Xamarin.Forms' namespaces and guides you toward the equivalent native MAUI implementations.

How does the skill know which version I am using?

The skill follows a reasoning framework that mandates reading your .csproj file to identify TargetFrameworks and PackageReferences before writing any code.

Does this skill support the latest .NET 10 releases?

Yes, it is specifically curated with a mapping table for .NET 10, including the transition from ListView to CollectionView and the removal of the legacy Device class.

Does it support alternative MAUI frameworks like MauiReactor?

Yes, the skill includes specific guidance for MauiReactor v3+ and Blazor Hybrid, ensuring you use the correct syntax for state management and web resource interception.

Mobile Development

Ensures .NET MAUI code remains current by preventing the use of deprecated, obsolete, or legacy Xamarin.Forms APIs during code generation and review.

The .NET MAUI Current APIs skill serves as an essential guardrail for modern cross-platform development, specifically designed to stop AI coding agents from generating outdated or non-functional code. By implementing a strict reasoning framework, it forces the AI to first detect the project's Target Framework (TFM) and NuGet library versions before suggesting code. It provides an extensive migration mapping for .NET 10, identifying traps like deprecated ListViews, the obsolete Device class, and legacy Compatibility namespaces, ensuring your mobile applications are built on the most stable and performant foundations available.

Key Features

01Version-aware library scanning for CommunityToolkit, MauiReactor, and Blazor Hybrid

02Enforcement of async-first naming conventions and native MAUI platform APIs

03Strict blocking of legacy Xamarin.Forms namespaces and compatibility wrappers

04Comprehensive mapping from deprecated controls like ListView and Frame to modern replacements

0580 GitHub stars

06Automatic Target Framework (TFM) detection for .NET 8, 9, and 10 projects

Use Cases

01Migrating existing .NET MAUI codebases to the latest .NET 10 standards

02Generating new UI layouts and logic that avoid common 'obsolete API' traps

03Performing automated code reviews to identify and replace deprecated Device and Animation calls
