Introduction to ASP.NET and Visual Studio

The aim of this guide is to introduce you to web applications developed using Microsoft ASP.NET, the famous web framework of Redmond taking advantage of the tools offered by Visual Studio development environment for reference. NET developers.

The online world offers many choices for development environments and in recent years ASP.NET has evolved, becoming one of the frameworks for the management of HTTP requests more consistent, stable and feature-rich on the world.

ASP.NET and Visual Studio, the popular Microsoft development environment, including a large amount of features that make life easier for web developers. For example, Visual Studio provides several project templates that you can use to develop a site and also supports different ways of distributing web applications, as we shall see.

Through the Visual Studio, you can test the site and analyze the critical areas of our code, in order to identify potential problems. Through designers can also develop advanced user interfaces very quickly and intuitively by moving the mouse controls to display in real time as they will appear in the final version of the application.

Using ASP.NET is therefore possible to create anything that you can find on the internet, e-commerce portals, sites for retrieval of records, to web services. To use this framework, however, need to learn how to use Visual Studio, known objects. NET Framework and know how to use a programming language objects from those provided by the framework (in our case we will use C #).

ASP.NET has been released for the first time in January 2002 with version 1.0. NET Framework and presented as the successor to Microsoft ASP technology (Active Server Pages). Unlike ASP.NET technology it is based, like all applications in the Microsoft. NET, the CLR (Common Language Runtime).

The CLR allows developers to write code using any of the high-level languages ​​supported by. NET Framework (C #, VB.NET, J #), but also other languages. This is because the CLR adheres to the ECMA (European Computer Manufacturers Association).

The strength of ASP.NET applications is that they are significantly better performance than that achieved by programming languages ​​interpreted due to the fact that the code is precompiled files managed by the web server.

The fundamental objective of all this is to make developing web applications as close as possible to the development of Windows applications. In fact, the ASP.NET controls work similarly to the corresponding controls of Windows applications and, as the latter, allow you to manage a variety of events (called event-driven model). In practice it is ASP.NET, which produces blocks of HTML code that are placed on the page that is sent to the end user's browser, reproducing the appropriate behavior of the controls.

After the launch of the first version of ASP.NET technology has been further improved and enriched with new features and is now arrived at version 4.0, including new features that represent the new frontier of modern web development: LINQ, AJAX, Silverlight, WPF (Windows Presentation Foundation) WCF (Windows Communication Foundation) and WF (Windows Workflow Foundation).
