Tech Trek: A Software Engineer's Guide to Code and Beyond

This is a step-by-step walkthrough which will create a new database using C# code. We will create one console Application which will create an empty database and will also add new tables too. Pre-Requisities We need to have Visual Studio 2013 installed to complete this walkthrough.(You can use older version too like 2010 or 2012 to complete this tutorial.) Apart from that, You will also need to have NuGet installed on your Visual Studio. Steps : 1. Create new Application Open Visual Studio, Click File -> New -> Project Click Console Application under templates -> Visual C# -> Windows Enter Name as CreateNewDatabase and Select OK 2. Create the Model Now we will create two simple model(Employee, Manager) using classes. As a part of demo I'll define both in Program.cs but in a real word application we should define in two separate file/classes. Add the following two classes in Program.cs. public class Manager ...

It is an enhancement to ADO.NET that gives developers an automated mechanism for accessing & storing the data in the database and working with the results in addition to DataReader and DataSet. It eliminates the need for most of the data-access code that developers usually need to write. It allows you to create a model by writing code or using boxes and lines in the EF Designer. Both of these approaches can be used to target an existing database or create a new database. It also provides services like change tracking, identity resolution, lazy loading, and query translation so that developers can focus on their application-specific business logic rather than the data access fundamentals. Following figure shows the overall architecture of the Entity Framework (Source : http://www.codeproject.com/ ) Application : Application which is going to use Entity Framework.
