Program Class​

Represents the main entry point for the arolariu.ro backend API. This class configures and bootstraps a .NET 9.0 STS (Standard Terms Support) modular monolith web application that provides invoice management and authentication services.

internal static class Program

Inheritance System.Object 🡒 Program

Remarks​

The application follows a modular monolith architecture pattern with clearly separated domains:

  • General domain: Core infrastructure, configuration, and cross-cutting concerns
  • Invoices domain: Business logic for invoice processing, analysis, and management
  • Authentication domain: User authentication and authorization services

The application is designed for deployment as a containerized service on Microsoft Azure, utilizing Azure services for storage, configuration, monitoring, and AI capabilities.

Configuration is applied in two phases:

  1. Builder configuration: Sets up services, dependencies, and middleware
  2. Application configuration: Configures the request pipeline and routing

Methods​

Program.Main(string[]) Method​

The main entry point for the application. Configures and starts the web application with all required domains and services.

public static void Main(string[] args);

Parameters​

args System.String[]

Command-line arguments passed to the application. These are used by the ASP.NET Core host for configuration overrides, environment specification, and other runtime parameters. Common arguments include --environment, --urls, and custom configuration keys.

Remarks​

The startup sequence follows this order:

  1. Create WebApplicationBuilder with default configuration sources
  2. Add general domain configuration (logging, telemetry, health checks, etc.)
  3. Add invoices domain configuration (business services, database contexts, etc.)
  4. Build the WebApplication instance
  5. Configure general application pipeline (middleware, routing, etc.)
  6. Configure invoice domain pipeline (endpoints, authorization policies, etc.)
  7. Start the application host

Each domain is responsible for registering its own services and configuring its own middleware through extension methods, promoting separation of concerns and modularity.
