ASP.NET Core

ASP.NET Core is a free, open-source, cross-platform framework for building modern, cloud-based, and internet-connected applications, such as web apps, APIs, and microservices. It is a redesign of the classic ASP.NET framework, optimized for performance, modularity, and deployment flexibility across Windows, Linux, and macOS. It integrates with modern development practices like dependency injection, configuration management, and middleware pipelines.

Also known as: ASP Core, DotNet Core Web Framework, ASP.NET 5+, AspNetCore, ASP.NET Core MVC

🧊Why learn ASP.NET Core?

Developers should learn ASP.NET Core when building scalable, high-performance web applications and APIs, especially in enterprise environments or cloud-native architectures using Microsoft technologies. It is ideal for scenarios requiring cross-platform deployment, microservices, real-time applications with SignalR, or integration with Azure services, offering advantages like built-in security, minimal overhead, and support for modern front-end frameworks like React or Angular.

.NET Core is a free, open-source, cross-platform framework for building modern applications, including web, cloud, mobile, desktop, IoT, and AI solutions. It is developed by Microsoft and supports multiple programming languages like C#, F#, and Visual Basic, with a modular architecture that enables high performance and scalability. It includes a runtime, libraries, and tools for developing and deploying applications on Windows, Linux, and macOS.

It is designed to be modular, high-performance, and runs on Windows, Linux, and macOS.

.NET Framework is a proprietary software framework developed by Microsoft that runs primarily on Windows. It provides a large class library called Framework Class Library (FCL) and language interoperability across several programming languages, enabling developers to build a wide range of applications, including desktop, web, and mobile. It includes features like memory management, security, and exception handling, and supports languages such as C#, VB.NET, and F#.

.NET MAUI is Microsoft's open-source (MIT-licensed) UI framework, the direct successor to Xamarin.Forms (Xamarin itself retired May 1, 2024, forcing migration). Current release is .NET MAUI 10, shipped alongside .NET 10 on November 11, 2025; latest servicing patch is 10.0.80 (June 24, 2026). Free, distributed with the .NET SDK, maintained by Microsoft on GitHub (dotnet/maui, 23.3k stars). Architecturally it wraps native platform controls (UIKit/AppKit, Android Views, WinUI 3) instead of rendering its own control set the way Skia-based rivals do. Native AOT compilation has been available (opt-in, via the PublishAot MSBuild property, applied on `dotnet publish` only) for iOS/Mac Catalyst builds since .NET 9 — it is not the default build path. Android has no Native AOT option at all; it still runs on Mono AOT, with CoreCLR slated to become the default mobile runtime across Android, iOS, and Mac Catalyst starting .NET 11. .NET 10 added a compile-time XAML source generator. Targets iOS, Android, Windows, and macOS (Mac Catalyst) only — no Linux or WebAssembly target. Current version/status: 10.0.80 (June 24, 2026) — .NET MAUI 10, shipped with .NET 10 GA Nov 11, 2025. License: MIT. Maintained by Microsoft (open source, dotnet/maui on GitHub).

.NET MAUI (Multi-platform App UI) is a cross-platform framework for building native mobile and desktop applications using C# and XAML. It allows developers to create a single codebase that can target Android, iOS, macOS, and Windows, leveraging the .NET ecosystem and providing a unified development experience. It is the evolution of Xamarin.Forms, integrated directly into the .NET platform.
