Introduction

Welcome to this ASP.NET tutorial. According to Microsoft, "ASP.NET is a technology for building powerful, dynamic Web applications and is part of the .NET Framework". This tutorial will teach you ASP.NET from scratch, and no knowledge of any kind of serverside scripting is required. Basic HTML and CSS knowledge is preferable. Having worked with Classic ASP or PHP won't give you much of an advantage, since ASP.NET is a whole new way of doing things.

.NET is language independent, which means you can use any .NET supported language to make .NET applications. The most common languages for writing ASP.NET applications are C# and VB.NET. While VB.NET is directly based on VB (Visual Basic), C# was introduced together with the .NET framework, and is therefore a some what new language. Some people call C# "the .NET language", but according to Microsoft, you can do all the same things, no matter if you're using C# or VB.NET. The 2 languages are not that different, and if you have used one of them, you will have no problems at all learning the other. In this tutorial we will use C#.

One of the main differences between ASP.NET and Classic ASP/PHP is the fact that ASP.NET is compiled, while Classic ASP is always interpreted. PHP can be compiled by using commercial products, but usually it's interpreted as well.

Ever since the first version of ASP.NET, the framework has evolved in so many ways and so has the tools for you as a developer. We will discuss this in the next articles, before we create our very first ASP.NET website.

ASP.NET - Web Forms or MVC?

Amikor az ASP.NET eredetileg megjelent, csak egyfajta módon működött. Később, a Microsoft a Ruby on Rails típusú keretrendszerek által inspirálva, képessé tette, hogy az MVC (Model-View-Controller) megközelítés is alkalmazható legyen weboldalak készítéséhez. Ezzel a lépéssel az ASP.NET felosztásra került ASP.NET Web Forms (az eredeti megközelítés) és ASP.NET MVC részre. Ezek rengeteg közös funkcionalitáson osztoznak, köszönhetően a .NET keretrendszernek, de rengeteg különbség van köztük, akár már egy egyszerű feladat megvalósításának módjában is.

Ebben az oktatóanyagban az ASP.NET Web Forms részére helyezzük a hangsúlyt.

IDE vagy szerkesztő?

This tutorial will use the free Visual Studio Community IDE from Microsoft. Despite what some people think, ASP.NET can be used without an IDE. It would be perfectly possible to write ASP.NET code in Notepad, and use the commandline compiler included with the .NET framework. Some people might actually prefer this "back to basics" way of doing things, but I believe that ASP.NET is best programmed with a decent IDE. You can use an IDE from another vendor, and you will still be able to follow most of this tutorial. We will use Visual Studio Community since it's free, quick to install and easy to use. Besides, using a good IDE will make a lot of things faster in the long run.

Download Visual Studio Community

So, to get started with this tutorial, go ahead and download Visual Studio Community from visualstudio.com. Here's a direct link to the download page:
