The intent of this book is to explain the basics of Entity Framework and the three data access approaches that Microsoft’s Entity Framework provides. This book covers the introduction to Entity Framework, how Entity Framework’s capabilities could be leveraged in .Net development irrespective of the type of application used, the key features of Entity Framework, what are the areas where Entity Framework could be used as an ORM and the history of Entity Framework. The book talks about various data access techniques that could be achieved using Entity Framework and use of code first migrations in Entity Framework. The querying options and various loading options of Entity Framework are explained with examples. The book also talks about the introduction to Entity Framework Core and its implementation details. The book would be more practical in nature thereby covering a less of theory and explaining the data access approaches in Entity Framework 6 and Entity Framework Core in any .Net application. The book chapters are in a tutorial format and showcase small data access applications using Entity Framework for the sake of understanding the concept. Once the concept and key capabilities of Entity Framework and Entity Framework Core are understood, those could be applied in any application based on need and requirement.
