Difference between asp and asp.net

"Classic" ASP uses vbscript for its code. ASP.NET allows you to use C#, VB.NET and other languages. ASP.NET gives you access to all the tools which come with the .NET framework and allows you to write object-oriented code.

They are too numerous to list here. I suggest you read ASP.NET compared with classic ASP Wikipedia.

ASP.NET is not the same as ASP. The "old" ASP is now called classic ASP. ASP.NET is a Markup Language can, among other things, use the server controls to run elements.

As for example:

<form id="MyForm" runat="server">

Then you said that it will run on the server and you have an id to control it.

• NET is the framework (such as a library)
  
• C #, J #, VB.NET, they are the main script languages for communicating with. NET
  
• ASP.NET is Markup Language .
  it runs on the server side. It generates xml / html / xHTML even further, to the user. In many ways one can compare ASP.NET, with WinForms. Then there is a way to visually show something to the user.
  

According to IndiaBIX's answers to ASP.NET interview questions:

The basic difference between ASP and ASP.NET is that ASP.NET is compiled whereas ASP is interpreted whereas. This implies that since ASP mainly uses VBScript, when an ASP page is executed, it is interpreted. On the other hand, ASP.NET uses.NET languages, such as C# and VB.NET, which are compiled to Microsoft Intermediate Language (MSIL).

Also see the section of the Wikipedia article that compares ASP.NET to ASP classic for a detailed comparison.

ASP is older (also called "classic ASP"). ASP.NET is newer, using the .NET framework.
