## Overview

Contoso is a small ASP.NET Core API with two capabilities: pizza catalog CRUD and generated weather forecasts. A client request enters the application configured in Program.cs, which maps controller endpoints. Pizza requests delegate to an in-memory service that stores Pizza records; weather requests generate forecast values directly in the controller. The sampled files show no persistent database or external service integration. The weather and pizza model links and controller calls are visible in the excerpts; no README documentation was provided.

Main entry points: [`Program.cs`](https://github.com/sullaspqr/pizza/blob/main/Program.cs) (HTTP app), [`Controllers/PizzaController.cs`](https://github.com/sullaspqr/pizza/blob/main/Controllers/PizzaController.cs) (Pizza endpoints), [`Services/PizzaService.cs`](https://github.com/sullaspqr/pizza/blob/main/Services/PizzaService.cs) (Pizza service), [`Controllers/WeatherForecastController.cs`](https://github.com/sullaspqr/pizza/blob/main/Controllers/WeatherForecastController.cs) (Forecast endpoint)
