Entity Framework Tutorials For Begineers and Professionals

Entity Framework Tutorials using C#

In this Entity Framework Tutorials Course using C#, I will discuss all the concepts of Entity Framework with Real-Time Examples. In this Entity Framework Tutorials article series, we will start from the very basics and, as we progress, cover all the intermediate and advanced features of Entity Framework as well.

Before .NET Framework 3.5, as a developer, we often wrote ADO.NET Code to perform CRUD operations with the underlying database. For this, we need to create a Connection Object with the database, then Open the Connection, Create the Command Object, and execute the Command using Data Reader or Data Adapter. Then, we create DataSet or DataTables to store the data in memory and perform different types of operations on the data as per the business requirements. Actually, this is a Time-Consuming and Error-Prone Process. Microsoft has provided a framework called “Entity Framework” to automate all these database-related activities for our application, and for this to work, we need to provide the necessary details to the Entity Framework.

What is Entity Framework?

Entity Framework is an Open-Source Object-Relational Mapping (ORM) Framework for .NET applications that enables .NET developers to work with relational data using domain-specific objects without focusing on the underlying database tables and columns where actually the data is stored. That means the Entity Framework eliminates the need to write the data-access code that developers usually need to write.

Official Definition: The Entity Framework is an Object-Relational Mapper (O/RM) that enables .NET developers to work with a database using .NET objects. It eliminates the need for most of the data-access code that developers usually need to write.

Why Entity Framework in .NET Applications?

Entity Framework is an ORM Tool. ORM tools increase developer productivity by reducing the redundant task of performing CRUD operations against a database in a .NET Application.

1. Entity Framework can generate the necessary database commands for doing the database CRUD Operation, i.e., it can generate SELECT, INSERT, UPDATE, and DELETE commands for us.
2. While working with Entity Framework, we can perform different types of operations on the domain objects (basically classes representing database tables) using LINQ to entities.
3. Entity Framework will generate and execute the SQL command in the database and then store the results in the instances of your domain objects so you can perform different types of operations on the data.

Entity Framework Versions:

In 2008, Microsoft introduced Entity Framework as part of .NET Framework 3.5. Since then, it has released many versions of Entity Framework. Currently, two of the latest versions are available: EF 6 (works with .NET Framework) and EF Core (works with .NET or .NET Core).

EF Version History:

1. EF 1.0 (or 3.5) in the year 2008 => .NET 3.5, Visual Studio 2008
2. EF 4.0 in the year 2010 => .NET 4.0, Visual Studio 2010
3. EF 5 in the year 2012 => .NET 4.0, VS 2012
4. EF 6 in the year 2013 => .NET 4.0 & .NET 4.5, VS 2012
