🚀 Entity Framework: Code First Approach in .NET Entity Framework (EF) is a powerful Object-Relational Mapper (ORM) that allows developers to work with databases using C# classes instead of raw SQL queries . 🔷 What is Entity Framework? As discussed in the previous blog, Entity Framework simplifies database interaction by mapping C# objects to database tables , enabling clean, maintainable, and strongly typed data access. +-------------------+ +---------------------+ +------------------+ | C# Classes | ----> | Entity Framework | ----> | Database | | (Entities) | | (ORM Layer) | | (Tables/Rows) | +-------------------+ +---------------------+ +------------------+ 🔷 Entities and Domain Classes 📌 Entity Classes Entity classes represent database tables . Each object represents a row. Example: public class Student { public int Id { get ; set ; } public string Name { get ; set ; }...
C# Keywords Many different reserved words or keywords are used in C# programming. They are categorised as described below. It is advised to properly get familiar with the categories, functionality, and usage of each of them before we move forward. If, somewhere, you feel you are not able to grasp the correct meaning, make a note of it and in the future specific examples where it is explicitly used, you would be able to recall and revise it. Some examples for certain keywords can be viewed at: Link 1. Data Types and Modifiers bool Explanation: Represents a Boolean value that can be either true or false . It is an alias for the system type System.Boolean . Example: bool isCoding = true; byte Explanation: Represents an 8-bit unsigned integer that can store values from 0 to 255. Example: byte age = 25; char Explanation: Represents a single 16-bit Unicode character. It is enclosed in single quotes. Example: char grade = 'A'; class Explanation: Used to declare a reference t...
