Designing and Versioning ASP.NET Core APIs

Good API design is critical in enterprise .NET Core systems.

Key practices:

1. Use resource-based URLs and HTTP verbs correctly.

2. Return appropriate status codes and problem details.

3. Implement API versioning (URL, header, or query-based).

Use libraries like ASP.NET API Versioning to manage multiple versions safely.

Architecture impact: Stable, versioned APIs allow independent evolution of clients and services.
