Beginner
This set of courses gets you up and running with EF Core by covering the most common scenarios you encounter with EF Core. You will build a data model with EF Core, see how to query and save data and how to deal with complex mappings that come up when building an application.
Entity Framework Core 2: Getting Started
2h 42m
Description
Entity Framework Core 2 is the newest version of Microsoft's O/RM for performing database persistence in .NET-based software. EF Core is a lightweight and extensible version of Entity Framework that has been written from the ground up. Whether you are new to EF Core or looking to see how to shift your earlier EF experience to EF Core, this course can help you get started. First, you'll learn how to define an EF Core data model to act as a bridge between your .NET objects and your database. You'll then learn how to interact with the data model using EF Core's various APIs. Finally, you'll be shown how to incorporate this model into a desktop application based on the .NET Framework and a cross-platform ASP.NET Core MVC application. By the end of this course, you will be able to build .NET framework, or .NET Core software using EF Core 2. All coding will be done in Visual Studio 2017 in a Windows environment.

Entity Framework Core 2: Mappings
1h 59m
Description
Entity Framework Core 2 is the latest version of Microsoft’s modern OR/M data access platform. In this course, Entity Framework Core 2: Mappings, you’ll explore how to efficiently utilize the latest version of Entity Framework Core to prepare yourself to work on production software. First, you’ll learn how to best build and interact with many-to-many and one-to-one relationships. Next, you'll discover how to take advantage of additional mappings such as the new shadow properties, scalar function support, and owned entities. Finally, you'll go over how to work with database views. By the end of this course, you'll be able to elevate your skill set and provide yourself with the tools you need to build your production application.

Intermediate
EF Core contains many new features designed to help you deal with advanced scenarios, and that is what you will learn in this section. This includes tapping into the EF Core pipeline with tracking events, using query types to access database views and using value converters to intercept and process values as they are read out of the database.
Entity Framework Core 2.1: What's New Playbook
3h 22m
Description
Every application uses data, and a thorough knowledge of Entity Framework Core is key to building successful .NET and .NET Core applications. In this course, Entity Framework Core 2.1: What's New Playbook, you’ll learn how to take full advantage of the most impactful features added to EF Core 2 in this update. First, you’ll learn how to use some returning features that work quite differently than they did in EF6, for example, data seeding, lazy loading and GroupBy queries. Next, you’ll explore some completely new features such as view mapping, change tracking event handlers, and type conversions. Finally, you’ll discover some of the small changes that can have a big impact on your code. When you’re finished with this course, you’ll have a deep knowledge of these important features in EF Core 2.1, enhancing your capability to create efficient and intelligent data access logic in your software.

EF Core contains the capability to manage your database schema from code, and in this segment, you will do a deep dive on EF Migrations, the technology behind this capability.
Entity Framework Core 2.1 Migrations: Fundamentals
2h 4m
Description
Entity Framework Core Migrations are Microsoft's recommended way of managing application databases. They are extremely powerful, but you have to understand how to use them. In this course, Entity Framework Core 2.1 Migrations: Fundamentals, you will learn the foundations of developing and deploying an enterprise application using migrations. First, you will learn how to create, test, and organize migrations. Next, you will discover how to resolve the conflicts that will inevitably arise. Finally, you will explore different methods of deploying database changes to higher environments, and determine which is most appropriate for going to production. When you are finished with this course, you will have the skills and knowledge of EF Core Migrations needed to build and deploy enterprise applications.
