C# SQL Server

Introduction to C# SQL Server

Integrating SQL Server with C# applications can be efficiently achieved using two primary technologies: Entity Framework Core (EF Core) and ADO.NET. Both methods provide robust solutions for interacting with SQL Server databases, each with its own advantages depending on your project's needs.

Using Entity Framework Core

EF Core is an Object-Relational Mapper (ORM) that allows developers to work with a database using .NET objects. It eliminates the need for most of the data-access code that developers usually need to write. Let's look at how you can use EF Core to interact with SQL Server.

After installing the package, you need to define your database context and entity classes. Below is an example of a simple DbContext and entity class.

Once your context and entities are set up, you can perform CRUD operations like so:

Using ADO.NET

ADO.NET provides a more traditional, lower-level approach to database interaction, giving you fine-grained control over your data access. Here's how to use ADO.NET to connect to SQL Server.

ADO.NET requires explicitly handling connections and commands, which can be advantageous when you need detailed control over database operations or are working in performance-critical applications.

Choosing Between EF Core and ADO.NET

Choosing between EF Core and ADO.NET depends on your project's specific requirements. EF Core is well-suited for applications that benefit from quick development and fewer lines of code, while ADO.NET may be preferred for applications requiring optimized performance and precise control over database operations.
