Setup

1. Create a .env file in the project root with the following content:

DATABASE_CONNECTION_STRING=Host=localhost;Database=eagleeye;Username=your_username;Password=your_password

2. Install dependencies:

dotnet restore

3. Run the application:

dotnet run

Architecture

The project follows SOLID principles and clean architecture:

• Single Responsibility Principle: Each class has a single responsibility
• Open/Closed Principle: Components are open for extension but closed for modification
• Interface Segregation: Interfaces are specific to client needs
• Dependency Inversion: High-level modules depend on abstractions

Components

• Models: Domain entities representing field agents
• Interfaces: Contracts for data access and services
• Repositories: Implementation of data access patterns
• Database: Entity Framework context and configuration
• Logging: Logging service implementations
• Core: Application entry point and business logic

Dependencies

• .NET 7.0
• Entity Framework Core
• Npgsql (PostgreSQL provider)
• DotNetEnv (Environment variable management)
