EntityFramework ADO.NET Entity Framework is an object-relational mapping(ORM) framework for the .NET Framework. It is designed to enable developers to create data access applications by programming against a conceptual application model instead of programming directly against a relational storage schema. It eliminates the need for most of the data-access code that developers usually need to write. So in this Online Entity Framework Tutorial you will understand how decent amount of code is been decreased and you’ll also learn how maintenance is required for data-oriented applications.
