Build and Run Instructions

Prerequisites

• .NET 9 SDK installed
• Visual Studio 2022 or VS Code with C# extension

Building the Solution

# Navigate to the solution root directory
cd TaskTracker

# Restore NuGet packages
dotnet restore

# Build the solution
dotnet build

# Run tests
dotnet test

Running the Application

# Navigate to the console app project
cd src/TaskTracker.ConsoleApp

# Run the application
dotnet run

Using the Application

Once running, you can use these commands:

• add <title> - Create a new todo item
• list - Show all todo items
• done <id> - Mark a todo as complete
• delete <id> - Remove a todo item
• exit - Quit the application

Database Files

The application creates two SQLite database files:

1. task_tracker.db - Contains todo items and telemetry data (logs, spans)
2. The database is automatically created on first run

Key Features Implemented

1. Clean Architecture: Proper separation of concerns with Domain, Application, Infrastructure, and Presentation layers
2. Dependency Injection: Full DI container setup using Microsoft.Extensions.DependencyInjection
3. Entity Framework Core: SQLite database with code-first approach
4. OpenTelemetry: Complete observability with:
   • Distributed tracing (Activities/Spans)
   • Structured logging
   • Custom SQLite exporters to persist telemetry
5. Async/Await: All I/O operations are asynchronous
6. Unit Testing: Comprehensive tests using xUnit and in-memory database
7. Modern C# 13: File-scoped namespaces, top-level statements, nullable reference types
8. Error Handling: Graceful exception handling throughout

This solution demonstrates production-quality patterns and practices for a .NET 9 console application with full observability and testing.
