ASP.NET Vs ASP.NET Core

ASP.NET and ASP.NET Core are two frameworks developed by Microsoft for building web applications. While they share some similarities, they also have some significant differences.

In this article, we will explore the differences between the two frameworks in detail based on the points listed below.

• Architecture
• Cross-Platform Support
• Performance
• Dependency Injection
• Configuration
• Middleware
• Web Forms Or Razor Pages.

Let's see in detail ASP.NET Vs ASP.NET Core

Architecture:

ASP.NET is built on the .NET Framework and uses the "System.Web" namespace. It follows a monolithic architecture, which means that all the components of the application are tightly coupled.
ASP.NET Core, on the other hand, is built on .NET Core and uses the "Microsoft.AspNetCore" namespace. It follows a modular architecture, which means that it allows developers to use only the components they need and leave out the rest.

Cross-Platform Support:

ASP.NET is primarily designed to run on the Windows operating system. While it is possible to run ASP.NET applications on other platforms using Mono, it is not officially supported.
ASP.NET Core, however, is designed to be cross-platform and can run on Windows, Linux, and macOS. This makes it a more versatile framework that can be used on a wider range of platforms.

Performance:

ASP.NET Core is faster and more lightweight than ASP.NET. This is because it has been optimized for performance and uses a modular architecture that allows for better scalability and faster response times.

Dependency Injection:

ASP.NET Core has built-in support for dependency injection, which makes it easier for developers to manage dependencies and make their code more testable.

ASP.NET does not have built-in support for dependency injection, although it is possible to use third-party libraries to achieve this functionality.

Configuration:

ASP.NET Core allows for configuration files to be stored in different formats, including JSON, XML, and INI files. It also supports environment-specific configuration files, which makes it easier to manage configuration settings across different environments.
ASP.NET, on the other hand, only supports XML configuration files, which can be more difficult to work with.

Middleware:

ASP.NET Core uses middleware to handle requests and responses. Middleware is a pipeline of components that process requests and can be added or removed as needed.
ASP.NET does not have middleware and instead uses HTTP modules and handlers to process requests.

Razor Pages:

ASP.NET Core introduces Razor Pages, which are a new way of building web pages using a page-based programming model. Razor Pages provide a simpler way of building web applications, especially for small to medium-sized applications.
ASP.NET does not have Razor Pages, and instead uses the Web Forms model for building web pages.

To Summarised, while ASP.NET and ASP.NET Core share some similarities, they also have significant differences.

ASP.NET is built on the .NET Framework, is primarily designed for Windows, and follows a monolithic architecture. ASP.NET Core is built on .NET Core, is cross-platform, follows a modular architecture, and is faster and more lightweight. ASP.NET Core also has built-in support for dependency injection, supports configuration files in multiple formats, uses middleware for handling requests, and introduces Razor Pages for building web pages.
