Entity Framework training course

Create Commercial .NET Applications That Use Object /Relational Mapping Using The .NET Framework

4.8 out of 5 average

(see feedback)

Overview

This Entity Framework training course will show the .NET ways of working with Object Relation Mapping.  How to both create or query relational databases.

Entity Framework has evolved over the years and supports both Full Framework and .NET Core; both of which can be covered.  

Whilst there are differences between Full Framework and .NET Core versions, there are many common features.  

The course shows how the Entity Framework can be used in a number of ways, either starting with an existing database or by creating entities in code from which a database can be created.  

As well as the usual Create, Read, Update and Delete functionality, support for transactions and change tracking will also be demonstrated.  .NET LINQ together with the use of Lambdas and Extension methods will be used to illustrate comprehensive capabilities to querying for data.  Asynchronous working will also be used.
