The Remote Learning Academy (RLA) is a modern, secure .NET Core-based e-learning platform that supports online education for students, professors, and assistants.
It includes robust features such as secure user authentication, course management, and student profile functionality — built with clean architecture principles.

• JWT-based authentication with refresh tokens
• Role-based registration (Student, Professor, Assistant)
• Two-Factor Authentication
• OAuth integration (e.g., Google)
• Email confirmation and password reset

• View all courses assigned to the professor
• View course details including:
  • Day of the week
  • Time
  • Location
  • Number of materials, quizzes, and discussions

• View enrolled students in a specific course
• See each student’s name and final grade for that course

• Upload lecture materials to a course
• Retrieve a specific material by ID
• List all materials for a course with:
  • Week number
  • Lecture title and description
  • File path

• Create new quizzes for a course
• Retrieve quiz details by ID
• List all quizzes in a course with:
  • Title
  • Max score
  • Term
  • Question count

• Start new discussions in a course
• Retrieve a specific discussion by ID
• List all discussions for a course with:
  • Professor’s name
  • Message
  • Post date
  • Author role (professor or not)

• All operations require authenticated professor access (via JWT)
• Identity verified through token sub claim
• Fine-grained access control:
  • Only professors assigned to a course can access or modify its data

• Clean architecture with separation of concerns
• Repository pattern: DbContext usage restricted to repositories
• Service layer encapsulates business logic
• DTOs used for clean and secure data transfer

• .NET 8.0 SDK
• SQL Server
• SMTP Server (e.g., Gmail) for sending emails
• Google OAuth credentials
• Visual Studio 2022 or VS Code

dotnet restore

Required packages:

• Microsoft.AspNetCore.Identity.EntityFrameworkCore
• Microsoft.EntityFrameworkCore.SqlServer
• Microsoft.AspNetCore.Authentication.JwtBearer
• Microsoft.AspNetCore.Authentication.Google
• OtpNet

dotnet ef database update --project RLA.Infrastructure

dotnet run --project RLA.API

The API will be available at:
https://localhost:5001

• Controllers
  Handle HTTP requests and delegate operations to the service layer.
  Examples: AuthController, StudentController

• Services
  Contain business logic and orchestrate operations between controllers and repositories.
  Examples: AuthService, StudentService

• Repositories
  Handle data access logic, interacting directly with the ElearningPlatformDbContext.
  Examples: StudentRepository

• Entities
  Represent the structure of database tables using domain models.
  Examples: ApplicationUser, Student, Course

• DTOs (Data Transfer Objects)
  Ensure clean and secure data transfer between layers and over the network.
  Examples: AuthResponseDto, CourseDto
