Create, Edit And Delete Operation Of Data In ASP.NET MVC

Introduction

This is a simple application for beginners that helps with how to perform create,edit,delete operations on a table in an ASP.NET MVC application. It also helps with how to create the database and add a table. We know that MVC is an integrated module. This is the integration of three words models,views,controllers. Models provide the business logic, Views isprovide the presentation and last controllers handle all of the requests that are provided by models,views. ASP.NET MVC gives you a powerful patterns-based way to build dynamic websites that enables a clean separation of concerns and that gives you full control over markup for enjoyable agile development. ASP.NET MVC is an alternative but not a replacement for ASP.NET Web Forms.
