On the one hand, ASP.NET Core is a continuation of the ASP.NET platform development. But on the other hand, it is not just another release. The release of ASP.NET Core actually means a revolution of the entire platform, its qualitative change.

ASP.NET Core is now entirely an opensource framework. All the source files of the framework are available on GitHub.

ASP.NET Core can run on top of the cross-platform .NET Core environment, which can be deployed on major popular operating systems: Windows, Mac OS, Linux. And thus, with ASP.NET Core, we can create cross-platform applications. And although Windows as an environment for application development and deployment still prevails, but now we are no longer limited to this operating system. That is, we can run web applications not only on Windows, but also on Linux and Mac OS. And for web application deployment we can use traditional IIS or cross-platform web server Kestrel.

Due to the modularity of the framework, all necessary components of a web application can be loaded as separate modules through the Nuget package manager. In addition, unlike previous versions of the platform, there is no need to use the System.Web.dll library.

ASP.NET Core includes the MVC framework, which combines the functionality of MVC, Web API and Web Pages. In previous versions of the platform, these technologies were implemented separately and therefore contained a lot of duplicate functionality. Now they are united in one program model ASP.NET Core MVC. And Web Forms are completely gone.

In addition to combining the above technologies into one model, a number of additional features have been added to MVC.

One such feature is tag helper, which allows you to more seamlessly combine html syntax with C# code.

ASP.NET Core is characterized by extensibility. The framework is built from a set of relatively independent components. And we can either use the built-in implementation of these components, or extend them using the inheritance mechanism, or create and use our own components with their own functionality.

Dependency management and project configuration have also been simplified. The framework now has its own lightweight container for dependency enforcement and there is no longer a need to use third-party containers such as Autofac, Ninject. Although they can also continue to be used if desired.

As a development toolkit, we can use the latest releases of Visual Studio, starting with Visual Studio 2015. In addition, we can create applications in the Visual Studio Code environment, which is cross-platform and can run on Windows, Mac OS X and Linux.

The new HTTP pipeline, which is based on Katana components and the OWIN specification, is now used to process requests. And its modularity makes it easy to add your own components.

This framework provides many tools for developing web applications, including:

• standalone web pages;
• web services;
• state management;
• authentication;
• authorization;
• caching;
• error handling and much more.

History of ASP.NET

The ASP.NET platform originated at the dawn of the Internet – in the 1990s. The first web pages were purely informative and therefore static. But quite quickly there was a need to add interactive elements to them. For example, forms for sending data to the server, chat rooms or shopping carts.

Then Microsoft began to develop tools for designing dynamic web pages. As a result, the company released the first version of Active Server Pages (ASP) in 1996. It was a server-side platform for creating dynamic Web pages in the VBScript or JScript scripting language.

At first, the first version of ASP was quite popular, but after a few years it became outdated and no longer met the modern (at that time) requirements of web development. Therefore, in 2000 Microsoft started working on a new version of the technology. Work on the next release of ASP began with renaming the project to ASP+.

ASP+ came out faster and more scalable, and it fixed problems related to security, state management, and deployment.

But the main innovation in ASP+ was the support of the C# language, introduced by Microsoft in 2000. Moreover, C# has become the main tool for creating web applications on the .NET platform.

In 2002, ASP.NET was released with the .NET Framework 1.0 platform. It provided developers with a powerful toolkit, including new tools such as:

• ASP.NET Web Forms;
• ASP.NET MVC;
• ASP.NET Web API.

ASP.NET became popular and sought after among web developers because it was flexible. It allowed the creation of complex Web applications that could handle large amounts of data and work with a variety of external sources, including databases.

Building on the ASP.NET project, in 2016 Microsoft released a new version of the platform called ASP.NET Core. The developers provided better performance, smaller application size, and compatibility with different operating systems including Linux and macOS.

One of the key changes in ASP.NET Core is a reworking of the architecture and underlying concepts. Instead of using Application Domain, ASP.NET Core uses namespaces and assemblies to organize and manage application code.

In addition, ASP.NET Core provides integrated support for building microservice applications and APIs. This opens the door for developers to design scalable applications.

ASP.NET working principle

• first comes the request from the client;
• when the user sends a request to the web server, ASP.NET accepts this request and starts processing it;
• there is a chain of handlers that can perform different tasks, for example, checking authorization or processing form data;
• ASP.NET then executes code on the server that can generate HTML, CSS, JavaScript, and other data to send back to the client;
• after generating the pages ASP.NET sends it back to the client as a response to its request.

Next, the platform maintains state between requests and responses, such as the use of cookies or sessions. State can be used, for example, to store user information to avoid re-authenticating each time a request is made.
