Introduction to Entity Framework Core

Entity Framework Core is a powerful and flexible ORM (Object-Relational Mapper) for .NET. It simplifies the process of working with databases by allowing you to map database tables to C# objects.

Key features include: Simplified database interactions, performance, type safety, and automatic code generation.

Defining Models

You define your data models using classes that represent the entities of your application.

Each model represents a real-world object and contains properties (data) and methods (operations).

Example:

                    class Product {
                        public string Name;
                        public decimal Price;
                        public string Description;
                    }
                

Creating Models

Using the Entity Framework Core.Model.CreateModel method, you can create a model from a class.

Example:

                    Model.CreateModel(new Product { Name = "Apple", Price = 1.00 });
                

Relationships

Define relationships between entities to represent foreign keys.

Example: Define a Many-to-Many relationship between Products and Orders.

Querying

Use LINQ to query data and retrieve results.

Example: Retrieve all products with a price greater than 10.
