ASP.NET is a web application framework developed and marketed by Microsoft to allow programmers to build dynamic web sites, web applications and web services. It was first released in January 2002 with version 1.0 of the .NET Framework, and is the successor to Microsoft's Active Server Pages (ASP) technology. ASP.NET is built on the Common Language Runtime (CLR), allowing programmers to write ASP.NET code using any supported .NET language.
ASP.NET web pages, known officially as "web forms", are the main building block for application development. Web forms are contained in files with an ".aspx" extension; these files typically contain static (X) HTML markup, as well as markup defining server-side Web Controls and User Controls where the developers place all the required static and dynamic content for the web page. Additionally, dynamic code which runs on the server can be placed in a page within a block <% -- dynamic code -- %>, which is similar to other web development technologies such as PHP, JSP, and ASP. With ASP.NET Framework 2.0, Microsoft introduced a new code-behind model which allows static text to remain on the .aspx page, while dynamic code remains in the .asp.cs page. 
184.108.40.206 Code-behind model:
Microsoft recommends dealing with dynamic program code by using the code-behind model, which places this code in a separate file or in a specially designated script tag. Code-behind files typically have names like MyPage.aspx.cs or MyPage.aspx.vb while the page file is MyPage.aspx (same filename as the page file (ASPX), but with the final extension denoting the page language). When using this style of programming, the developer writes code to respond to different events, like the page being loaded, or a control being clicked, rather than a procedural walk through the document.
ASP.NET's code-behind model marks a departure from Classic ASP in that it encourages developers to build applications with separation of presentation and content in mind. 
A directive is special instructions on how ASP.NET should process the page. The most common directive is <%@ PageÂ %> which can specify many things, such as which programming language is used for the server-side code.
220.127.116.11 User controls:
User controls are encapsulations of sections of pages which are registered and used as controls in ASP.NET. User controls are created as ASCX markup files. These files usually contain static (X) HTML markup, as well as markup defining server-side web controls. These are the locations where the developer can place the required static and dynamic content. A user control is compiled when its containing page is requested and is stored in memory for subsequent requests. User controls have their own events which are handled during the life of ASP.NET requests. An event bubbling mechanism provides the ability to pass an event fired by a user control up to its containing page. Unlike an ASP.NET page, a user control cannot be requested independently; one of its containing pages is requested instead. 
18.104.22.168 Custom controls
Programmers can also build custom controls for ASP.NET applications. Unlike user controls, these controls don't have an ASCX markup file, having all their code compiled into a dynamic link library (DLL) file. Such custom controls can be used across multiple web applications and Visual Studio project  .
22.214.171.124 State management:
ASP.NET applications are hosted by a web server and are accessed using the stateless HTTP protocol. As such, if an application uses statefull interaction, it has to implement state management on its own. ASP.NET provides various functions for state management. Conceptually, Microsoft treats "state" as GUI state. Problems may arise if an application needs to keep track of "data state"; initialize. State management in ASP.NET pages with authentication can make Web scraping difficult or impossible  .
126.96.36.199 Application State:
Application state is held by a collection of shared user-defined variables. These are set and initialized when the application_onstart event fires on the loading of the first instance of the application and are available until the last instance exits. Application state variables are accessed using the Applications collection, which provides a wrapper for the application state variables. Application state variables are identified by name.
188.8.131.52 Session state:
Server-side session state is held by a collection of user-defined session variables that are persistent during a user session. These variables, accessed using the Session collection, are unique to each session instance. The variables can be set to be automatically destroyed after a defined time of inactivity even if the session does not end. Client-side user session is maintained by either a cookie or by encoding the session ID in the URL itself.
ASP.NET supports three modes of persistence for server-side session variables  .
184.108.40.206 in-Process Mode:
The session variables are maintained within the ASP.NET process. This is the fastest way; however, in this mode the variables are destroyed when the ASP.NET process is recycled or shut down  .
220.127.116.11 ASP State Mode
ASP.NET runs a separate Windows service that maintains the state variables. Because state management happens outside the ASP.NET process, and because the ASP.NET engine accesses data using .NET Remoteing, ASPState is slower than In-Process. This mode allows an ASP.NET application to be load-balanced and scaled across multiple servers. Because the state management service runs independently of ASP.NET, the session variables can persist across ASP.NET process shutdowns. However, since session state server runs as one instance, it is still one point of failure for session state. The session-state service cannot be load-balanced, and there are restrictions on types that can be stored in a session variable  .
18.104.22.168 SQL Server Mode
State variables are stored in a database, allowing session variables to be persisted across ASP.NET process shutdowns. The main advantage of this mode is that it allows the application to balance load on a server cluster, sharing sessions between servers. This is the slowest method of session state management in ASP.NET  .
ASP.NET aims for performance benefits over other script-based technologies (including Classic ASP) by compiling the server-side code to one or more DLL files on the web server. This compilation happens automatically the first time a page is requested (which means the developer need not perform a separate compilation step for pages). This feature provides the ease of development offered by scripting languages with the performance benefits of a compiled binary. However, the compilation might cause a noticeable but short delay to the web user when the newly-edited page is first requested from the web server, but won't again unless the page requested is updated further.
The ASPX and other resource files are placed in a virtual host on an Internet Information Services server (or other compatible ASP.NET servers; see other implementations, below). The first time a client requests a page, the .NET Framework parses and compiles the file(s) into a .NET assembly and sends the response; subsequent requests are served from the DLL files. By default ASP.NET will compile the entire site in batches of 1000 files upon first request. If the compilation delay is causing problems, the batch size or the compilation strategy may be tweaked.
Developers can also choose to pre-compile their "code behind" files before deployment, using MS Visual Studio, eliminating the need for just-in-time compilation in a production environment. This also eliminates the need of having the source code on the web server  .
2.1.3 Difference between ASP & ASP.Net
ASP (Active Server Pages) is Microsoft's early foray into the server side scripting engines that were meant to dynamically create web pages as they are needed. An example of a dynamically created web page is an on-line calculator where you input two numbers and after you're done it presents you with the sum. Creating that in HTML would require a lot of pages, one for each possible result. But with ASP, you can write a single short script that can handle this easily. ASP has seen a fair share in the internet creating pages on the fly. But on January 5, 2002 Microsoft released the successor of ASP called ASP.NET.
ASP.NET aims to make the transition to web programming easier for those who are already knowledgeable in creating programs for Windows.Â ASP.NET also offered some improvements over its predecessor. Here are some of the advantages of ASP.NET over ASP:
ASP.NET takes advantage of the additional features in the .NET library allowing its pages to be coded in any of the other languages included in .NET.
ASP.NET also has a very wide array of libraries and controls that can be used to build a web page quickly and easily. It also had a lot of the commonly used templates like menus.
Error Handling has also been improved compared to ASP by making use of the try-catch blocks and exception handling.
A compiled code format allowed ASP.NET scripts to perform faster during execution since it doesn't need to be compiled by the server when called. It also meant a lot less errors when it is already deployed since errors were easily found when you attempt to compile a script.
One of the best improvements of ASP.NET is the use of a WYSIWYG (What You See Is What You Get) control creation system, that gave developers a GUI that helps them gain a quick visual feedback on the look of their page  .
2.2 Visual Basic.NET
Visual Basic .NET (VB.NET) is an object-oriented computer programming language that can be viewed as an evolution of the classic Visual Basic (VB) which is implemented on the .NET Framework. Microsoft currently supplies two major implementations of Visual Basic: Microsoft Visual Studio, which is commercial software and Microsoft Visual Studio Express, which is free of charge.
Visual Basic... A name everybody knows for a rich, easy and GUI based programming language, making each & every task easier and improves programmer's productivity. VB has won the best RAD (Rapid Application Development) Tool award for three times and still keeping itself at top  .

13) it supports interoperability
14) uses managed code
15) Supports threading
16) Powerful exceptional handling
17) More than one version of dll is supported.
18) Vb.net is fully object orientated, high security, used in mobile application  .
2.3 Difference between ASP.Net & VB.Net
Asp.net is simple a library that makes it easy for you to create web applications that run against the .NET runtime (similar to the java runtime). Vb.net is a language that compiles against the common language runtime, like C#. Any .NET compliant language can use the asp.net libraries to create web applications  .
2.4 Microsoft Visual Studio
It is an Integrated Environment developed by Microsoft. This software/tool is used to develop the console and GUI applications. Using this tool we are able to create the windows application, web sites, web applications, and web services. We use them in both native code together with managed code for all the platforms, that supported by Microsoft Windows.
Visual Studio includes a code editor as well as code refectory. Built in tools include designer for building GUI applications, web designer, class designer, and data base schema designer.
Visual Studio supports different type of programming languages by means of language services. Visual studio specify built-in languages include C/C++ (via Visual C++), VB.NET (via Visual Basic .NET), C# (via Visual C#), and F# (as of Visual Studio 2010).
22.214.171.124 CODE EDITOR
It supports syntax highlighting and code completion and also uses intellisence for not only variables, functions and methods but also language constructs like loops and queries. Intellisence support XML and for Cascading Style sheets and java scripts when developing web sites and web applications. Visual Studio has features that have a background compilation. As code is being written, visual studio compiles it in background and provide feedback about syntax and compilation error.
It works both as a source -level debugger and as a machine -level debugger. Debugger can work with both managed code as well as native code and can be used for debugging applications that was be written in any languages. This also creates memory dumps and then loads them later for debugging. The debugger supports Edit and Continue, i.e., it allows code to be edited as it is being debugged.
It is a host of visual designer to aid in the development of applications. These tools are:
