Understanding Detailed Architecture of ASP.NET 4.5

ASP.NET has extended into multiple code frameworks, including Web Forms, MVC, Web Page, Web API and SignalR. Initially, all these grew up separately but now they are coming together. Now, you can develop your web site or web application by using Web Forms or MVC or Web Page and services by using Web API or SignalR.

Components of Asp.NET 4.5 Architecture

01. .NET Framework

.Net framework is an integrated component of windows operating system that supports development and execution of next generation applications, Windows store apps and services.

02. ASP.NET Framework

ASP.Net Framework is used to create dynamic website, web application and web services. It is built on the top of .NET Framework.

Asp.NET Framework provides you various capabilities like Hosting Model, Site/Service Management, Protocol Abstraction, Security, Caching capability, Routing and Model Binding etc.


Mainly, Asp.Net can be divides into two parts – Asp.Net Sites and Asp.Net Services.

03. Asp.NET Site

There are following flavours of Asp.NET Site –

Web Forms

This is the traditional event driven development model. It has drag and drop server controls, server events and state management techniques. This best for rapid application development (RAD) with powerful data access.


This is a lightweight and MVC (Model, View, Controller) pattern based development model. It provides full control over mark-up and support many features that allow fast & agile development. This best for developing lightweight, interactive and device oriented (i.e. compatible to smart phones, iPhone, tablet, laptop etc.) web application with latest web standards.

Web Pages

This is also a lightweight and Razor syntax based development model. It has built-in template and helpers also provide full control over mark-up. It is best for developing beautiful web application with latest web standards. You can also use WebMatrix which is a free tool and has built-in template; for developing Asp.Net Web Page.


SPA stands for Single Page Application which helps you to build web applications that include significant client-side interactions using HTML5, CSS3 and JavaScript. It is best to make highly interactive single page dashboard web applications.

04. Asp.NET Services

There are two ways to make Asp.Net Services as given below –


Asp.Net Web API is a framework for building HTTP services that can be consume by a broad range of clients including browsers, mobiles, iphone and tablets.


ASP.NET SignalR is a library that simplifies the process of adding real-time web functionality to applications. Real-time web functionality is the ability to have server code push content to connected clients instantly as it becomes available, rather than having the server wait for a client to request new data.

05. Visual Studio 2012

The Visual Studio IDE offers a set of tools that help you to write and modify the code for your programs, and also detect and correct errors in your programs. Using Visual Studio 2012 you can build Windows Store apps, desktop apps, mobile apps, ASP.NET web apps, and web services.
