WCF Modernization: CoreWCF or gRPC?

Overview

Hi everyone, I recently put together a guide on modernizing legacy WCF applications, and I'd appreciate some feedback from developers who have been through this transition.

The article covers:

• Best practices for testing existing WCF services before migration
• Common challenges when maintaining legacy WCF applications
• When CoreWCF is a good fit
• When it makes more sense to adopt gRPC
• Factors to consider before starting a migration project

Goals

My goal wasn't to suggest that every WCF application should be migrated immediately. Instead, I wanted to provide a practical framework for evaluating the available options based on business and technical requirements.

Questions for the Community

I'd love to hear from the community:

• Are you still maintaining WCF services?
• If you've migrated, did you choose CoreWCF, gRPC, or another approach?
• What was the biggest challenge during your migration?

Looking forward to hearing your experiences and learning from the community.
