 What is Asp.net  What is difference between Asp.net and php  install Visual Web Developer 2010 Express and Visual Studio

 ASP.NET is a development framework for building web pages and web sites with HTML, CSS, JavaScript and server scripting.  ASP.NET is a web application framework developed and marketed by Microsoft to allow programmers to build dynamic web sites.

 The ASP.NET application codes can be written in any of the following languages:  C#  Visual Basic. Net  Jscript 6

 Both PHP and ASP.NET are server side technologies that provide frameworks to develop web applications. The differences between these two server technologies namely PHP and ASP.NET are: 7

 PHP is an open source technology which can be used for free.  ASP.NET is a Microsoft technology that is expensive in price.  PHP is a programming language that is used for creating web applications.  ASP.NET is a platform in which programming languages such as VB.NET or C# can be used to create ASP.NET applications. 8

 PHP will work well in any kind of platform and server.  ASP.NET can be used only with Internet Information Server (IIS).  PHP was launched by Rasmus Lerdorf in the year  ASP.NET was launched by Microsoft in the year

 Let’s start with a “Hello, World” ASP.NET application.  We will use Visual Studio’s built in web server to test and demonstrate our web application code. 14

 In Visual Studio 2010  File > New Web Site (NOT New project ) 15

 There is a pair of “solution” files in the Projects directory. 19

 Hello.sln holds Visual Studio settings associated with this web site (project).  You can look at it with WordPad.  Hello.suo is a binary file  These files are used only by Visual Studio.  Not part of the web app.  Not deployed to a web server.  Both of these files can be reproduced at any time if they are deleted.  Can generally be ignored. 20
