## What is ASP.NET?
ASP.NET is a fundamental web development platform used to create websites, applications, and web services. It is the integration of HTML, CSS, and JavaScript. Originally ASP.net was released in 2002. The first version of Asp.Net deployed was 1.0. The Recent Version of Asp.Net is 4.6.

Asp.Net works on HTTP (Hypertext Transfer Protocol) and uses the HTTP commands and policies to set a browser-to-server bilateral communication.

ASP.NET is a part of the Microsoft .NET Framework. The following image shows the component stack.

1. Web Forms: ASP.NET web forms extend the event-driven model of interaction to web applications. It is used to develop an application with data access and also provides server-side and event to create an application.

2. Asp.Net MVC: The ASP.NET MVC web development framework employs the MVC design pattern. Unlike ASP.NET, where the view is predetermined, .NET MVC separates app functionality, view data, and model data. It enables you to use critical features like URL authorization, Windows and form authentication, data caching, output management, state management, configuration system, and many more.

3. Asp.Net Web Pages: It is used to create dynamic web pages. It combines server code with HTML in a fast way.

The following table illustrates each development model.

2. Library - The .NET Framework is a set of a standard class library of reusable classes, interfaces, and value types for ASP .NET development process and system functionality

3. Common Language Runtime (CLR) - The CLR is used to perform code activities. Activities include exception handling and garbage collection mostly.

## What Is ASP.NET Core?

Asp.net Core is a new version of Asp.net released by Microsoft. It is an open-source platform used to develop a web framework and can be executed with different browsers like Windows, Mac, or Linux. ASP.Net Core is a new version of asp.net. It is a free open source that can run on different OS like Mac, Windows, and Linux. It was originally launched as ASP.NET 5 but later it was renamed to ASP.NET Core and still with the same name.

Now that you are perfectly aware of the key distinctions between ASP.NET Core vs ASP.NET, there are certain questions that many experts still get confused about. Let’s go through them.

## Is .NET Core and ASP.NET Core the same?
Many individuals get puzzled when they discover about .Net Core vs Asp.Net Core. Even though they seem similar but there is a small yet critical difference between them.

ASP.NET Core is a web-specific framework used for API and web app development. It is simply implemented on top of .NET CORE.

While .NET Core is a general-purpose programming framework for app development.

## Difference between .NET vs .NET Core
Another difference where individuals get confused is .NET vs .NET Core.

.NET framework is an open-source and leading modern web and app development platform with impeccable support for cross-platform compatibility while .NET CORE is an upgraded version of ASP NET framework.

Another difference where individuals get confused is .NET vs .NET Core.

Understanding the differences between ASP.NET vs .NET Core and ASP.NET Core vs .NET Core is essential especially when you try to pick .NET as your career.

ASP.NET development has established itself as a standard in the world of cutting-edge technologies, convincing clients to embrace it for commercial efforts. ASP NET framework has gained new levels of flexibility and increased performance with its newest foundation, .NET Core while remaining a tried-and-true framework and a cornerstone for top-notch web app development.

Let's delve into the key disparities between these two frameworks: .NET vs ASP.NET Core.

## Key Features of ASP.NET Framework:
ASP.NET is a rich ecosystem for [custom software development](https://www.ifourtechnolab.com.au/custom-software-development-company) offering WebForm features and MVC architecture support. Although this framework provides you with such amazing features, it also has the limitation of being supported by just the Windows platform.

However, the newest version of the ASP.NET framework, .NET Core, has cross-platform compatibility, making .NET even more secure. This is the most important difference between asp.net and asp.net core that everyone should be aware of.

## Advantages of ASP.NET Core Over ASP.NET:
Enhanced modularity: ASP.NET Core helps you with enhanced modularity that makes developers easily use the components they require.

**Cross-platform support:** ASP NET CORE is open-source in nature and offers you amazing features. What makes it even more interesting is its cross-platform compatibility support. This allows developers to build projects of various requirements scenarios.

**Lightweight and high performance:** The platform is lightweight and known for delivering high performance. This platform helps you with seamless speed and scalability for your business application.

**Remarkable security:** ASP.NET Core offers both built-in and third-party identity providers to manage authentication. You may enhance project security using CORS management, HTTPS enforcement, app secrets, and so on.

## Conclusion
In conclusion, learning the key differences between ASP.NET and ASP.NET Core is essential to make effective decisions during .NET web development. Of course, these two frameworks belong to the so-called ASP.NET ecosystem and have similar goals of creating robust and dynamic web applications, they exhibit distinct features catering to different development scenarios.

Ultimately, the choice between .NET and .NET Core hinges on project requirements, technical constraints, and long-term goals. Evaluating factors such as platform compatibility, performance demands, development team expertise, and deployment environment will guide the decision-making process.

As the technology landscape continues to evolve, both frameworks will play distinct roles, ensuring that developers have the tools they need to build powerful and responsive web applications.
