Entity Framework is defined as an open-source object-relational mapper (ORM) framework for .NET applications which is supported by Microsoft. It mainly increases the developer’s productivity as it provides developers to work with data using objects of domain-specific classes without focusing on the underlying database tables and columns where these data are stored. It also eliminates the need of the data-access code which is used to interact with the database which developers usually need to write. It gives an abstract level to the developers to work with a relational table and columns by using the domain-specific object. It mainly reduces the code size of the data for the specific applications and also the readability of the code automatically increases. This is the new technology for accessing the data for Microsoft application. The latest version of Entity Framework is 6.0.
