Course description

We’ll start the course with a look at how you can customize an entity data model to make it easier for application developers to use its entity objects. The model designer in Visual Studio has plenty of options for refining a model, as well as make it easier to work with large, complex models with hundreds of entities. To finish up you’ll also learn some best practices of model design, so that you can build robust applications that take full advantage of the right Entity Framework infrastructure.


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: Querying and Updating Data course before taking this course.
