Intro:
Many developers are still confused: should they prepare with .NET Core or stick with the classic .NET Framework for interviews?
In 2025, which one are hiring managers more likely to care about? Let’s break it down simply.

🔹 .NET Framework (The Old Guard)

Windows-only

Mature and stable ecosystem

Still used in many enterprise companies

Useful if you’re working with legacy projects

🔹 .NET Core (The Modern Hero)

Cross-platform (Windows, Linux, macOS)

High performance

Designed for cloud-native apps

Microsoft is focusing all future updates on it

🔥 Interview Perspective

If you’re preparing for new projects or modern companies → focus on .NET Core

If you’re targeting enterprise/legacy environments (banking, insurance, government IT) → knowing the .NET Framework is still valuable

🧠 Simple Analogy

Think of .NET Framework as an old Ambassador car 🚗
and .NET Core as a Tesla ⚡
The Ambassador still runs, but the future belongs to Tesla.

✅ Conclusion

If you can only pick one for 2025 → learn .NET Core.
But if you also know .NET Framework, it gives you bonus points in interviews.
