SQL Server with Applications: Entity Framework Core Tutorial

Create a Product Model and DbContext

Define a Product class with properties Id, Name, and Price. Create a DbContext with a DbSet<Product> and configure it to connect to a local SQL Server database.

Expected output: A working DbContext class connected to SQL Server with a Product entity.

Hint: Use data annotations or Fluent API to configure the model if needed.

Perform CRUD Operations

Using your DbContext, add a new product, query products with price above a threshold, update a product's price, and delete a product.

Expected output: Code that performs all CRUD operations successfully.

Hint: Use Add, LINQ queries, SaveChanges, and Remove methods.

Apply a Migration

Add a new property to the Product model and create a migration to update the database schema accordingly.

Expected output: A migration script generated and applied to the database.

Hint: Use the EF Core CLI or Package Manager Console commands for migrations.

Entity Framework Core is an ORM that allows .NET developers to interact with SQL Server databases using .NET objects, simplifying data access and reducing the need for manual SQL.

You configure DbContext by overriding OnConfiguring or using dependency injection to specify the SQL Server connection string with UseSqlServer method.

Migrations are a way to incrementally update the database schema to keep it in sync with the data model defined in code.
