Entity Framework 6.1, Part 6 of 6: Code-First Dev

Course description

This course will start by covering how code-first works by default, which will probably work for most applications early in their development cycle. But when you’re ready to deploy the application to a production server, or need more flexibility in how Entity Framework creates a database. You’ll see how to create a code-first model and create a database from it, and see an application that makes use of it to maintain data in the database. You’ll also learn how to customize the database using both data annotations and the DBModelBuilder API, which lets you write code instead of use data annotations. Last you’ll see how code migrations is a newer feature of code first that goes beyond just deleting and recreating the database when the model changes.

Each LearnNowOnline training course is made up of Modules (typically an hour in length). Within each module there are Topics (typically 15-30 minutes each) and Subtopics (typically 2-5 minutes each). There is a Post Exam for each Module that must be passed with a score of 70% or higher to successfully and fully complete the course.

Prerequisites

This course assumes that you are experienced with relational database design and programming concepts. Entity Framework is all about data access, and the course doesn’t spend any time on data fundamentals. You’ll also need a good understanding of object-oriented programming in C#, so that you know how to use the entity data objects that Entity Framework generates from your data model. You’ll also need to have a working knowledge of Language INtegrated Queries (LINQ) in C#. The course uses Entity Framework with various SQL Server databases, so you should know enough about SQL Server to know how to perform various tasks and be able to connect to a database. But you don’t need deep knowledge of SQL Server to use Entity Framework productively. You should have already viewed the Entity Framework 6.1: SQL Server Features course before taking this course.
