It contains the specifications for the .Net supported languages and implementation of language integration. Classes, interfaces, structures, and enumerated values, which are collectively called types. This way, the server becomes aware of the overall application state and operates in a two-tiered connected way. ASP.NET works on top of the HTTP protocol, and uses the HTTP commands and policies to set a browser-to-server bilateral communication and cooperation. Database application – must have SQL database knowledge. Now for processing of the file, it is redirected to the script engine for the further task by the webserver.

Microsoft also provides Visual Studio Code, a lighter-weight IDE and editor, which is free for everyone, including corporations. ASP.NET is built on the CLR which allows the programmers to execute its code using any .NET language(C#, VB etc.). An open-source web application framework developed by Microsoft in web development design is ASP.Net. The application is developed on the server-side and helps in making dynamic web pages. ASP.Net is written in .Net languages and has an Apache license.

The ASP.NET Component Model technology gives us full freedom to control our development and can be used anywhere, whether it is a small or big project. As it is managed by Microsoft, it can never be yesterday’s technology as Microsoft has invested a lot in its development and community. So as a whole, we can say ASP.NET will undoubtedly be the tool of choice for most Web developers for the next five to ten years. ASP.NET executes a web page using the object-oriented programming approach.

  • For example, you might have an ASP.NET API that interacts with your React frontend.
  • After you have learned the theoretic basics of ASP.NET, we can now move to the practical part!
  • Whether you use Blazor Server or Blazor WebAssembly is up to you.
  • Blazor WASM is responsive and fast, and can even be deployed as a static site served with just NGINX.
  • Blazor WebAssembly basically takes the entire server as well as the .NET runtime and runs it on top of WASM.
  • Not only this, ASP.NET applications can be accessed with all of the popular databases, MySQL, MariaDB, Postgres, Microsoft SQL Server, CouchDB, and MongoDB.

Blazor Desktop should be released in November of 2021 with .NET 6’s first preview. Library – The .NET Framework includes a set of standard class libraries. The most common library used for web applications in .net is the Web library. The web library has all the necessary components used to develop.Net web-based applications. ASP.Net applications can also be written in a variety of .Net languages.

Assembly is a logical unit consisting of the assembly manifest, type metadata, IL code, and a set of resources like image files. ASP.NET is used to produce interactive, data-driven web applications over the internet. It consists of a large number of controls such as text boxes, buttons, and labels for assembling, configuring, and manipulating code to create HTML pages. The future of ASP.NET technology is very bright and great in accordance with the coming years as it has become today’s leading platform for web development. As the .net core is open source and it is really growing rapidly, we can say it has a very vast and developing scope in the future. Interpreted code is not directly executed by the machine, but must be read and interpreted each time before being executed.

The error indicates that the runtime will not convert a double to an int without explicit type casting. This type of type casting is known as explicit type casting because you must write explicit code to perform the type casting. Following these steps will create a new .NET Core console application project in Visual Studio 2022. We’ll use this project to work with type conversions in the subsequent sections of this article.


This explains why you cannot have both implicit and explicit operators in a class. Although an implicit cast is more convenient to use, an explicit cast provides better clarity and readability of your code. This makes it uniquely positioned to compete with frameworks like React, as it’s essentially the first true competitor to JavaScript for client web applications. Blazor is a new web framework from Microsoft designed to compete with industry-leading platforms like React.

They plan to completely get rid of the dependence on a browser and JavaScript and just run a native container with a web view that’s .NET all the way down. Blazor Server, which works like React Server Side Rendering and does most of the processing on the server. If you have a backend that requires high performance, C# will also run a lot faster than JavaScript. Even though JS is by no means slow and has improved a lot over the years, it will still end up less performant than C#, which actually runs pretty close to native C++ performance. And get a daily digest of news, geek trivia, and our feature articles. An ASP.NET page is nothing more than a text file with the extension .aspx.

Programming models

In the beginning, there was just ASP.NET, which can be used to make all sorts of web applications. There was ASP.NET MVC (Model-View-Controller), which creates data-driven web pages, and ASP.NET WebAPI, which specializes in backend APIs. These were recently merged into a unified package with the modernized ASP.NET Core.

So ASP.Net can remember the cart items and pass it over to the purchase page. Code Behind Mode – This is the concept of separation of design and code. By making this separation, it becomes easier to maintain the ASP.Net application. There will be another file called MyPage.aspx.cs which would denote the code part of the page.

This gives the websites a lot of strength and versatility. ASP.NET is a web framework designed by Microsoft Inc. that is extensively used to build robust web applications. In this article, we will analyze why ASP.NET should be chosen over other accessible web frameworks. The following code snippet shows how you can take advantage of the explicit operator to convert an Author instance to an instance of AuthorDto class. The following code snippet shows how you can take advantage of the implicit operator to convert an Author instance to an AuthorDto instance.

So Visual Studio creates separate files for each web page, one for the design part and the other for the code. The ASP.NET runtime transforms the .aspx page into an instance of a class, which inherits from the base class page of the .Net framework. Therefore, each ASP.NET page is an object and all its components i.e., the server-side controls are also objects. ASP.NET makes the internet as a software platform much easier to manage web programming.

ASP.NET AJAX – An extension with both client-side as well as server-side components for writing ASP.NET pages that incorporate Ajax functionality. This will create your private key file; in this example, the filename is test-prvkey.pem. Joydip Kanjilal is a Microsoft MVP in ASP.Net, as well as a speaker and author of several books and articles. He has more than 20 years of experience in IT including more than 16 years in Microsoft .Net and related technologies. The following two methods show how you can convert an Author instance to an AuthorDto instance and convert and AuthorDto instance to an Author instance. In the “Additional information” window shown next, choose “.NET 7.0 ” as the framework version you want to use.

Blazor Server vs. Blazor WebAssembly

In this chapter, you will see some basic fundamental of the .Net framework. This is only relevant when you get involved in complex / advanced deployments. The application server inside IIS comes into asp net usage play when you set permissions and thread pools for a particular website (dedicated / non dedicated) etc. ASP.NET web forms extend the event-driven model of interaction to the web applications.

Can You Use Blazor on Desktop (Electron)?

The basic architecture of the ASP.Net framework is as shown below. There are some standalone Application Servers for Windows Web based applications. It is the technology used for working with data and databases. It provides access to data sources like SQL server, OLE DB, XML etc. The ADO.NET allows connection to data sources for retrieving, manipulating, and updating data.

At W3Schools every example displays the hidden ASP code. This will make it easier for you to understand how it works. At W3Schools you will find complete ASP references about built-in objects and components, and their properties and methods. When a browser requests a normal HTML file, the server just returns the file. Our “Show Example” tool makes it easy to learn ASP, because it shows ASP code with parallel HTML output. ASP.Net is a framework which is used to develop a Web-based application.

Build & Deploy an ASP.NET Core App to Azure App Service

On IIS6.0 and lower, pages written using different versions of the ASP framework cannot share session state without the use of third-party libraries. This does not apply to ASP.NET and ASP applications running side by side on IIS 7. With IIS 7.0, modules may be run in an integrated pipeline that allows modules written in any language to be executed for any request.

That’s why we termed ASP.NET as a subset of the .NET Framework. The request of a dynamic Web page differs much from the static one. After the server has received the inquiry, it will be send to the ASP.NET engine. If the file exists, ASP.NET will not simply send the content back, instead it will create a new dynamic page that will be send back to the client. This dynamic page can look different from user to user.
