ASP.NET Core Web API – Learning Project ??

This project is a learning playground where I practice and implement core concepts of ASP.NET Core Web API development.
It covers everything from Entity Framework relationships to API design, and authentication & authorization with role-based access.

---

?? Topics Covered

1. Entity Framework Core Relationships

• One-to-One (1:1)
  Example: User ? Profile
• One-to-Many (1:N)
  Example: User ? Posts, Post ? Comments
• Many-to-Many (M:N)
  Example: Users ? Groups (with a join table)

---

2. API Building

• CRUD (Create, Read, Update, Delete) endpoints
• DTOs & AutoMapper usage
• Pagination for large datasets
• API Versioning

---

3. Data Handling

• Filtering – get specific subsets of data
• Sorting – order data by fields
• Searching – search by keywords
• Pagination – split large results into pages

---

4. Authentication & Authorization

• JWT (JSON Web Tokens) Authentication
• Role-based Authorization
  • Admin, User, Student roles
• Login & Register endpoints
• Secure password hashing with ASP.NET Core Identity
