ASP.NET Core Overview – Ek Modern Web Framework

Aaj hum baat karne wale hain ek aise framework ki jo aapke web development experience ko next level pe le ja sakta hai – ASP.NET Core.

Ye ek modern, cross-platform, open-source framework hai jo high-performance web apps, APIs, IoT apps, aur mobile backends banane ke kaam aata hai. Ye traditional ASP.NET ka complete re-written version hai – fast, lightweight aur flexible.

 Kya Hai ASP.NET Core?

ASP.NET Core ko .NET Core ke upar build kiya gaya hai aur ye modular architecture follow karta hai. Matlab – jo chahiye, wahi load karo.

• No extra bloat

• High performance

• Smaller memory footprint

• Easy maintenance

Chahe aapki app cloud pe ho ya local server pe – ASP.NET Core dono jagah easily run kar sakti hai.

 Kyun Use Karein ASP.NET Core?

Yahan kuch solid reasons hain jo ASP.NET Core ko ek excellent choice banate hain modern app development ke liye:

1. Cross-Platform Support

Windows, Linux, ya Mac – koi bhi OS ho, ASP.NET Core wahan run karega.

2. Performance Beast

Old System.Web.dll ki dependency hata di gayi hai. Sirf required packages use karo – faster requests, better scalability.

 3. Built-in Dependency Injection

Inbuilt IoC container se app maintain karna aur test karna bohot easy ho jaata hai.

4. Front-End Friendly

React, Angular, Bootstrap – sab integrate ho sakta hai easily. Modern UI frameworks ke sath full support!

5. Host Anywhere

IIS ho ya Apache ya Nginx – ASP.NET Core app har jagah host ho sakti hai.

6. Code Reusability

Ek hi library ko .NET Framework, Mono jaise alag environments me reuse kar sakte ho.

 7. Side-by-Side App Versions

Multiple versions ki apps ek hi machine pe run kar sakti hain without conflicts.

8. Small Deployment Size

.NET Core ke sath aata hai, jo kaafi lightweight hai. Toh deployment size bhi chhota hota hai.

ASP.NET Core is Truly Cross-Platform

ASP.NET Core apps self-hosted hoti hain using Kestrel, jo internal web server hai. External web servers (like IIS, Apache) reverse proxy ka kaam karte hain.

Web Request Flow:

1. Client se request → IIS/Apache

2. Forward hoti hai → Kestrel

3. Middleware handle karta hai

4. Response milta hai → Client

Simple and efficient!

ASP.NET Core Versions Timeline

ASP.NET originally 2002 me launch hua tha. 2016 me aaya ASP.NET Core – aur tab se game change ho gaya!

Microsoft ne .NET 5 ke baad se ASP.NET Core ko simplify karke ASP.NET hi bolna shuru kar diya, lekin technology wahi Core wali hai.
