Purpose and Topology

This is a C# starter repository containing three independent console-assignment applications: contact management, OOP demonstrations, and inventory management. The root solution, CSharp_Assignments.sln, is the primary development entry point; each assignment also has its own executable project and Program.cs.

Runtime Entry and Application Bootstrap

Each application starts in its project entry point, then delegates to an application runner/controller flow:

• src/BasicContactManagerAssignment1/Program.cs

• src/Assignment2BasicsOfOOPs/Program.cs

• src/Assignment3InventoryManagement/Program.cs

ApplicationRunner.cs exists in assignments 2 and 3 as a likely composition/bootstrap boundary:

• src/Assignment2BasicsOfOOPs/ApplicationRunner.cs

• src/Assignment3InventoryManagement/ApplicationRunner.cs

The material runtime is .NET/C# console applications; no web runtime, database, or remote service is represented in the tree.

Console Presentation and Control Flow

All assignments follow an interactive console architecture: console I/O and views collect/display user-facing data, controllers coordinate commands and navigation, and services perform domain operations.

• src/Assignment3InventoryManagement/View/ConsoleView.cs

• src/Assignment3InventoryManagement/Controller/MainController.cs

• src/Assignment3InventoryManagement/IO/IConsoleIO.cs

The control boundary is deliberately explicit: UI-facing classes should not own persistence or domain rules, while controllers/services mediate those interactions.

Contact Management Domain

Assignment 1 implements a basic contact-management flow. The controller coordinates the console UI, validation, manager service, and repository around ContactInfo.

• src/BasicContactManagerAssignment1/Controller/ContactController.cs

• src/BasicContactManagerAssignment1/Services/ContactManager.cs

• src/BasicContactManagerAssignment1/Models/ContactInfo.cs

Persistence is abstracted as a repository implementation, creating a separate storage boundary even though no external database provider is visible:

• src/BasicContactManagerAssignment1/Persistence/Repository.cs

• src/BasicContactManagerAssignment1/Validation/ContactValidator.cs

OOP Demonstration Domain

Assignment 2 groups three domains—bank accounts, employees, and shapes—under a main controller and separate domain controllers/services. It is structured to exercise inheritance/polymorphism and domain-specific validation.

• src/Assignment2BasicsOfOOPs/Controller/MainController.cs

• src/Assignment2BasicsOfOOPs/Services/BankService.cs

• src/Assignment2BasicsOfOOPs/Models/BankAccount.cs

Representative subtype hierarchies include account types, employee roles, and shapes:

• src/Assignment2BasicsOfOOPs/Models/CheckingAccount.cs

• src/Assignment2BasicsOfOOPs/Models/Developer.cs

• src/Assignment2BasicsOfOOPs/Models/Shape.cs

Inventory Management Pipeline

Assignment 3 is the most explicitly layered application. MainController drives user operations; InventoryService exposes inventory behavior through an interface; Repository supplies storage through IRepository; validation gates product input.

• src/Assignment3InventoryManagement/Controller/MainController.cs

• src/Assignment3InventoryManagement/Services/IInventoryService.cs

• src/Assignment3InventoryManagement/Persistence/IRepository.cs

Primary flow: console input → controller → validation/service → repository → Product results → console view. Sorting is modeled as a domain-level option:

• src/Assignment3InventoryManagement/Models/Product.cs

• src/Assignment3InventoryManagement/Validation/IProductValidation.cs

• src/Assignment3InventoryManagement/Models/Enum/SortField.cs

Quality and Delivery Infrastructure

GitHub Actions provides build/test/coverage automation:

• .github/workflows/BuildTestCoverage.yml

The repository reserves separated acceptance and unit-test roots, while contributor workflow emphasizes project-per-assignment development and pull requests:

• tests/acceptance/Directory.Build.props

• tests/unit/Directory.Build.props

• README.md
