Upgrading Your ASP.NET Core 1.x Web API to 2.0
ASP.NET Core 2.0 introduced significant improvements—but upgrading legacy 1.x APIs requires understanding breaking changes and new patterns. This focused course walks you through the migration process step-by-step, ensuring your APIs remain stable and leverage modern performance gains.
AIU.ac Verdict: Essential for backend engineers maintaining ASP.NET Core 1.x codebases who need a structured upgrade path. Kevin Dockx’s hands-on approach covers real migration scenarios, though you’ll need existing ASP.NET Core fundamentals to get maximum value.
What This Course Covers
The course tackles the core migration landscape: breaking changes between versions, dependency injection shifts, routing updates, and middleware configuration differences. You’ll work through practical scenarios including API endpoint refactoring, authentication/authorisation adjustments, and testing strategies post-upgrade.
Beyond syntax changes, Dockx emphasises performance optimisation opportunities in 2.0—caching improvements, response compression, and async/await patterns. You’ll apply these concepts to real API scenarios, ensuring your upgraded services perform better than their 1.x predecessors.
Who Is This Course For?
Ideal for:
- Backend engineers: Managing ASP.NET Core 1.x APIs in production who need a clear upgrade roadmap without downtime risks
- Technical leads: Planning team migrations and needing to understand scope, timeline, and potential pitfalls before committing resources
- Full-stack developers: Responsible for both API and client-side code who want to understand 2.0’s breaking changes and their downstream impact
May not suit:
- ASP.NET Core beginners: This assumes solid 1.x knowledge; start with core fundamentals before tackling migration-specific content
- Greenfield project teams: Building new APIs from scratch should skip this and learn 2.0+ directly—migration context won’t apply
Frequently Asked Questions
How long does Upgrading Your ASP.NET Core 1.x Web API to 2.0 take?
The course runs 1 hour 17 minutes. Most engineers complete it in one focused session or split across two shorter sittings.
Do I need ASP.NET Core 1.x experience to benefit?
Yes—this course assumes you’re already working with 1.x APIs. If you’re new to ASP.NET Core, build foundational knowledge first.
Will this course cover upgrading to versions beyond 2.0?
No, this focuses specifically on the 1.x-to-2.0 migration. Principles apply to later upgrades, but version-specific changes aren’t covered.
Can I apply this to APIs currently in production?
Absolutely—Dockx covers migration strategies designed for live systems, including testing approaches and rollback considerations.
