What exactly is ASP.NET?

ASP.NET is a Microsoft-created open-source web platform for creating modern online applications and services using .NET
ASP.NET is a cross-platform technology that works on Windows, Linux, Mac OS X, and Docker.

The .NET platform

.NET is a developer platform that consists of tools, programming languages, and frameworks that may be used to create a wide range of applications. The fundamental platform includes components that can be used in a variety of projects. .NET is extended with components for constructing various types of apps by platforms like ASP.NET.

The.NET platform includes the following features:
  • The programming languages C#, F#, and Visual Basic
  • The base libraries cover strings, dates, files/IO, and more.
  • Windows, Linux, macOS, and Docker editors and tools
ASP.NET expanded .NET

ASP.NET is a platform for implementing online applications that expands the.NET platform with tools and libraries.
The following are some of the features that ASP.NET brings to the.NET platform:

C# or F# is a base framework for processing internet traffic.
Razor is a web-page template for creating dynamic web pages in C#.
Model View Controller, for example, is a library for basic web patterns (MVC)
Multi-factor authentication and external authentication with Google, Twitter, and other services are included in this verification system, which also includes libraries, a database, and template pages for managing logins.
Extensions for the editor give syntax highlighting, code completion, and other features tailored to web page development.

Back-end code

Back-end code, such as business logic and data access, is written in C#, F#, or Visual Basic when utilizing ASP.NET.

You may access the wide ecosystem of packages and libraries available to all.NET developers since ASP.NET extends .NET. You can also create your own libraries that can be shared across all .NET-based applications.

C#, HTML, CSS, and JavaScript create dynamic pages.

Razor uses HTML and C# to provide a syntax for constructing dynamic web pages. Your C# code is analyzed on the server, and the resulting HTML output is sent to the customer.

JavaScript is the language used to write application code. ASP.NET interfaces with JavaScript frameworks and contains pre-configured themes for SPA frameworks such as React and Angular

Windows, Linux, macOS, and Docker are all supported.

On Windows, Linux, macOS, and Docker, ASP.NET apps can be written and run. The Visual Studio product series includes tools for developing.NET applications on any operating system. Many prominent editors also provide command-line tools and extensions.

What is ASP.NET Core?

If you're familiar with ASP.NET, you've probably heard of ASP.NET Core. The open-source and cross-platform version of ASP.NET is called ASP.NET Core. For all modern innovations, you should utilize ASP.NET Core. Prior to the release of ASP.NET Core, the Windows-only versions of ASP.NET were simply referred to as ASP.NET. Although ASP.NET Core receives the most of the development, previous versions continue to receive modest updates and bug fixes.
