TaskManager Interview Project

A .NET 8 technical interview exercise implementing a task management system with Clean Architecture, TDD, JWT authentication, Docker, SQL Server, and a Angular frontend.

User Story

As a user, I want to manage my personal tasks so that I can track my work and deadlines efficiently.

Technical Decisions

• No Entity Framework.
• No Dapper.
• No Mediator/MediatR.
• Data access is implemented with ADO.NET using Microsoft.Data.SqlClient.
• Clean Architecture is used to separate API, Application, Domain, and Infrastructure concerns.
• SQL Server runs in Docker.
• Demo data and credentials are seeded automatically.

Architecture

TaskManager.Api
  -> Controllers, authentication, HTTP concerns

TaskManager.Application
  -> Use cases, services, DTOs, repository contracts

TaskManager.Domain
  -> Entities, enums, domain validation

TaskManager.Infrastructure
  -> SQL Server repositories, JWT, password hashing

Dependency direction:

Api -> Application -> Domain
Infrastructure -> Application + Domain
