Learning Entity Framework Core

Introduction to Entity Framework Core 6 lectures 30:19 The Course Overview This video provides an overview of the entire course. What is an O/RM Some of the viewers might not have any prior experiences with O/RMs so they might not know what an O/RM is. • Understand O/RM • Learn about EF Core Starting a New Project We need to work on a small starting project. • Start a new ASP.NET Core 2.0 project The Database Context The Database context is vital to application development with Entity Framework Core. The viewers need to know more about it. • Show an example of DbContext • Create a new DbContext • Add two DbSets to the newly created DbContext Creating the Database The viewers have created a new project, installed EF Core and even created a DbContext but they haven’t yet seen a database. • Register the DbContext with DI • Create a static DbInit class • Get an instance of the DbContext and call EnsureCreated The SQL Server Object Explorer The viewers would want to view the fake data inserted in the database. The SQL Server Object Explorer is a very helpful tool for that job. • Pull up the SQL Server Object Explorer • Use the View Data feature • Drop the database Introduction to Entity Framework Core 6 lectures 30:19 The Course Overview This video provides an overview of the entire course.

Migrations are still possible with the command line. • Create a new project add entities and a DbContext • Guide the viewer through the installation of the required packages • Demonstrate the basic migration operations in the CMD Create, Execute, and Roll Back Migrations. 5 lectures 32:13 What is a Migration Viewers without prior exposure to O/RMs have no knowledge of what an O/RM is. • Provide a detailed explanation of what migrations are • Describe the advantages of using migrations Our First Migration Following a theoretical introduction the viewers will need to know how to create their own migrations. • Add entities to the project • Add a DbContext • Execute the migrations and update the database Updating a Table In order to demonstrate one of the key benefits of using migrations we need to attempt to update a table. • Make the change in the model • Create a new migration • Execute the migration and inspect the change in SQL Server Object Explorer Rolling Back After having created and updated a table the viewers will want to know how they can go a step back. • Make an intentional mistake during the creation of an entity • Apply that migration • Roll back to a correct state An Alternative: The Command Prompt In the videos so far we’ve used the PMC to work with migrations.
