Visual Studio is an integrated development environment for writing, compiling, and debugging the code. It provides a complete set of development tools for building ASP.NET web applications, web services, desktop applications, and mobile applications.
The Visual Studio IDE The new project window allows choosing an application template from the available templates.
When you start a new web site, ASP.NET provides the starting folders and files for the site, including two files for the first web form of the site. The file named Default.aspx contains the HTML and asp code that defines the form, and the file named Default.aspx.cs (for C# coding) or the file named Default.aspx.vb
(for VB coding) contains the code in the language you have chosen and this code is responsible for the actions performed on a form. The primary window in the Visual Studio IDE is the Web Forms Designer window. Other supporting windows are the Toolbox, the Solution Explorer, and the Properties window. You use the designer to design a web form, to add code to the control on the form so that the form works according to your need, you use the code editor..
Projects and Solutions A typical ASP.NET application consists of many items: the web content files (.aspx), source files (.cs files), assemblies (.dll and .exe files), data source files (.mdb files), references, icons, user controls and miscellaneous other files and folders. All these files that make up the website are contained in a Solution. When a new website is created, VB2008 automatically creates the solution and displays it in the solution explorer. Solutions may contain one or more projects. A project contains content files, source files, and other files like data sources and image files. Generally, the contents of a project are compiled into an assembly as an executable file (.exe) or a dynamic link library (.dll) file. Typically a project contains the following content files:
Page file (.aspx)
User control (.ascx)
Web service (.asmx)
Master page (.master)
Site map (.sitemap)
Website configuration file (.config)

Selecting Start
Selecting Start Without Debugging from the Debug menu,
