How does it handle authentication during migration?

The guide provides patterns for bridging legacy JWT authentication with modern schemes, ensuring the service layer can forward credentials correctly during the transition.

What is the Strangler Pattern in this context?

It is a strategy for incrementally replacing legacy .NET controllers with new Minimal API endpoints, using feature flags to safely route traffic between the old and new systems.

Which frameworks does this guide support?

It specifically focuses on migrating from .NET Framework (Express-Web-API) to .NET 6+ (Actions.API) using the MediatR request/handler pattern.

Does this guide include testing procedures?

Yes, it outlines a four-phase TDD process: capturing real behavior, creating red tests, implementing green code, and final strangler integration.

API 开发

Guides the gradual migration of legacy .NET controllers to modern Minimal APIs using the Strangler Fig pattern.

关于

This skill provides a comprehensive framework for incrementally replacing legacy .NET Framework systems with modern .NET 6+ architectures. It offers specific implementation patterns for controller strangling, feature flag-driven routing, and MediatR-based handler patterns, ensuring zero downtime and reliable rollback capabilities during high-risk API migrations. By following the included TDD-driven process, developers can maintain behavioral parity while modernizing their backend infrastructure.
