What is

ASP.NET a fundamental web development platform used to create websites, applications and web services. It is the integration of HTML, CSS and JavaScript. Originally was released in 2002. The first version of Asp.Net deployed was 1.0. The Recent Version of Asp.Net is 4.6.

Asp.Net works on HTTP (Hypertext Transfer Protocol) and uses the HTTP commands and policies to set a browser to server bilateral communication.

ASP.NET is a part of the

Microsoft .NET Framework

. The following image shows the component stack.

ASP.Net Introduction

ASP.NET provides three development styles for creating web applications:

  • Web Forms
  • ASP.NET Web Pages
  1. Web Forms: ASP.NET web forms extend the event-driven model of interaction to web applications. It is used to develop an application with data access and also provide server-side and event to create an application.
  2. Asp.Net MVC: it gives an MVC (Model-View-Controller) patterns base way builds the dynamic website. Those patterns use to user-interface(View), data(Model), and application logic(controller). The model is responsible for maintaining application data and logic. The view is a user interface of the application, which displays the data. The controller handling user request passes the request View and model.
  3. Asp.Net Web Pages: It is used to create dynamic web pages. It combines a server code with HTML in a fast way.

The following table illustrates each development model.

Model Skills Development style Experience
Web Forms Win Forms, WPF, .NET Rapid development using a rich library of controls that encapsulate HTML markup Mid-Level, Advanced RAD
MVC Ruby on Rails, .NET Full control over HTML markup, code and markup separated, and easy to write tests. The best choice for mobile and single-page applications (SPA). Mid-Level, Advanced
Web Pages Classic ASP, PHP HTML markup and your code together in the same file New, Mid-Level

ASP.Net Architecture

This .NET framework has the following key components.

  1. Language - A .NET Framework is a variety of programming languages including VB.NET and C#.
  2. Library - The .NET Framework is a set of a standard class library of reusable classes, interfaces, and value types for ASP .NET development process and system functionality.
  3. Common Language Runtime(CLR) - The CLR is used to performing code activities. Activities include exception handling and garbage collection mostly.

What Is Core: Core is a new version of released by Microsoft. It is an open-source used to develop a web framework and can be executed with different browsers like Windows, Mac or Linux. ASP.Net is a new version of It is a free open source which can run on different OS like Mac, Windows and Linux. It was originally launched as an ASP.NET 5 but later it was renamed to ASP.NET Core and still with the same name.

ASP.Net Core Introduction

Asp.Net Core is a cloud-based cross-platform framework to build web apps on Windows, Mac, and Linux including the

MVC framework

. It is a combination of MVC and WEB API in a single web programming framework.

Difference Between Asp.Net VS Asp.Net Core

Asp.Net Build for Windows Asp.Net Core Build for Windows, Mac and Linux
Asp.Net has a Good Performance ASP.Net core has higher performances than ASP.Net 4x.
It runs on .Net Framework or commonly called as full .Net Framework It runs on .Net Core and Full .Net Framework.
Asp.Net Supports WebForm, Asp.Net MVC and Asp.Net WebAPI. Asp.Net Core does not support WebForm. It supports MVC, Web API and Asp.Net Web pages originally added in .Net Core 2.0.
Asp.Net used the only IIS with dependant on System.web.dll. Asp.Net Core has not dependant System.web.dll and so the IIS.
Support C#, VB and many other languages and also support WCF, WPF and WF Support only C#, F# language. VB support to added a short time and no support WCF, WPF and WF but support for WCF client libraries are available.
Asp.Net MVC application added Web.config, Global.asax, Application Start. Core did not support Web.config and Global.asax files. It is supporting appsettings.json.
Container support not more than better as the ASP.Net Core application. Container support best suited for deployments like Docker.
All major versions supported Support Core from Visual Studio 2015 update 3 and current version VS 2017.
We Need to re-compile after the code change. Core Browser refresh will compile and executed the code no need for re-compile.
