Can I perform an incremental migration while keeping the app functional?

Yes, the skill includes a 'Dual Targeting' section that shows you how to target both .NET Framework and modern .NET simultaneously using conditional compilation.

How does it handle breaking changes like the removal of BinaryFormatter?

It identifies deprecated APIs and suggests modern alternatives, such as migrating from BinaryFormatter to System.Text.Json or other secure serializers.

Does it support the latest versions of .NET?

Absolutely. The skill provides guidance and templates for migrating to .NET 6, .NET 8, and even previews for .NET 10.

Can this skill help with WinForms interop during migration?

Yes, it provides specific project file configurations (UseWindowsForms: true) to ensure legacy interop remains functional in a modern WPF environment.

Does it support automated migration tools?

It provides instructions for using the 'try-convert' tool for automated initial passes, followed by manual steps for complex project cleanup.

Developer Tools

Guides the modernization of legacy WPF applications from .NET Framework to modern .NET 6+ environments.

About

This skill provides a structured framework for upgrading legacy Windows Presentation Foundation (WPF) applications to modern .NET versions (6, 8, and beyond). it streamlines the transition from the old MSBuild project format to the modern SDK-style format, manages NuGet package migrations, and identifies breaking API changes. It offers detailed patterns for dual-targeting during gradual migrations and helps developers implement modern C# features like nullable reference types and file-scoped namespaces to improve code quality and performance.

Key Features

Automated and manual SDK-style project file conversion
Dual-targeting configuration for incremental migration strategies
Breaking change resolution for removed APIs like BinaryFormatter and Remoting
Optimized deployment patterns for Self-Contained and Single-File publishing
Modern .NET feature implementation including Nullable and Global Usings
6 GitHub stars

Use Cases

Modernizing legacy project structures to the latest SDK-style formats
Migrating WCF client and WinForms interop code to modern desktop standards
Upgrading enterprise WPF applications from .NET Framework 4.8 to .NET 8 or 10
