ASP.NET is a server-side, open-source web application framework. Developed by Microsoft that allows developers to create applications and web pages for PC as well as mobile devices.
It was first introduced to the market in January 2002 with version 1.0 of the .NET Framework.
ASP.Net works at the top of the HTTP protocol and uses HTTP policies and commands to set the browser for server collaboration and communication.
ASP.NET is part of the Microsoft .NET platform, the code is written using reusable and extensible components or objects in the .NET framework.
What is ASP.NET Core?
ASP.NET Core is the latest version of ASP.NET that runs on every computing platform such as macOS, Linux, and Windows. It is open source like ASP.NET, developed by Microsoft. It allows developers to develop web services, dynamic content-driven sites and web applications.
Why should I use ASP.NET?
There are several reasons to use ASP.NET when creating an application or website. Multiple language support, low cost, and speed are the main reasons for using it.
ASP.NET has a built-in Windows server environment, which requires less setup and configuration than other web development platforms.
The Applications built into ASP.net are far more efficient and faster than websites built with PHP. Because whenever the ASP.NET application is configured, which means the code is compiled into the object code and then executed. Once the code is compiled, it will be quickly and repeatedly run to the .net platform.
Architecture and Components of ASP.NET:
ASP.NET is a framework used to build web-based applications. The basic architecture of the ASP.NET Framework and the jobs they perform:
- Languages : There are many languages in the .Net Framework, such as C #, J #, Jscript, and Basic Visual. C# and VB.net are used to develop web applications.
- Library: The .NET Framework includes a number of libraries used to develop web applications. The most common library used for web applications is .net. This library has all the important essentials that are used to develop web-based .net applications.
- Common Language Runtime (CLR): CLIR is a platform that allows the .Net programs to execute. It is used to perform key functions including memory management, security checking, discount handling, debugging, thread execution, code security, thread execution, compilation, and authentication. The code administered directly by the CLR is called managed code. When the managed code is compiled, the compiler translates the source code into the CPU independent, then a Just in Time (JIT) compiler translates the compiled Intermediate Language (IL) code into the native code.
- Common Type System (CTS): CTS provides guidelines about how to using and managing types during runtime, as well as cross-level communication.
- ASP.NET AJAX: ASP.NET is the web development model and AJAX is the extension of it for implementing and developing the AJAX functionality. ASP.NET AJAX includes components that allow developers to update a web page without reloading the entire page.
- Assemblies and metadata: An assembly is a logical unit that consists of metadata, assembly manifesto, IL code, and a set of resources such as images. Metadata is binary information that describes programs, either stored in memory or a portable executable file.
- Windows Forms: Contains all the graphical information of any window that appears in the applications.
- ADO.NET: This is a technology that works with databases and data. It provides access to data sources such as XML, SQL Server, etc. This helps in connecting data sources, updating data, and retrieving data.
Characteristics of ASP.NET
Below are some key Characteristics of ASP.NET:
- State Management: ASP.NET provides a state management facility, which means that the entire application is in one place, so we do not need to access data from different places.
- Caching: ASP.NET also provides caching facility. Caching plays a vital role in application performance. By caching, pages or sections that are often requested by the user can be stored in temporary memory or location. These components and pages can be retrieved in a better way and provide faster feedback to the users.
- Code behind the Mode: The Code behind the mode means that the ASP.NET application code is stored in a separate file or script tag. The files behind the code are usually named index.aspx or style.aspx.cc. The code behind the model encourages ASP.NET programmers to create web apps with content separation and presentation in mind.
- Fast Speed: Applications and websites built into ASP.net are far more efficient and faster than the many other server side languages. Because whenever the ASP.NET application is configured, which means the code is compiled into the object code and then executed. Once the code is compiled, it will be quickly and repeatedly run to the .net platform.
ASP.NET is a server-side web and application development language. It is designed to work with HTTP protocol standards.
