Entity Framework Core is the new version of Entity Framework after EF 6.x. It is open-source, lightweight, extensible and a cross-platform version of Entity Framework data access technology. In this post, we modeled an entertainment problem domain using code-first design. In addition to modeling, we applied our schema to an SQLite database. Finally, we used the expressiveness of LINQ to generate SQL queries and return our result set. EF Core users who want to write the query starting with the Ratings property cannot currently do so due to some EF Core query generator limitations.
Entity Framework is an Object-Relational Mapper which enable the .NET developers to work with the database using the .NET objects. It eliminates the need for accessing the code of the data that developers need to write. Entity Framework Core uses a provider model to access many different databases.

Actors playing characters in multiple productions
Our subject matter is Entertainment, both movies and television, which we’ll call Productions. I hope as folks read these sentences, they start to formulate the relationships in their mind. We’ll design a schema for entertainment productions using a code-first approach, migrate an SQLite database to our schema’s current incarnation, seed our database, and run some typical LINQ queries. https://deveducation.com/ in C# is an object relational mapping framework. In this article, we will see how to use Entity Framework in a C# application.
