## Overview

CustomerAPI is an ASP.NET Core service for customer, employee, designation, product, and user administration, with JWT authentication, role/menu permissions, and product-image handling. Clients call controller endpoints; controllers query or update the EF Core context, which connects to SQL Server. Product image endpoints also read and write files under wwwroot. The graph reflects sampled controller and startup code; other controller details and configuration values were not inspected.

Main entry points: [`Models/Learn_DBContext.cs`](https://github.com/nihira2020/dotnetcore_api_jwttoken/blob/master/Models/Learn_DBContext.cs) (EF Core context), [`Startup.cs`](https://github.com/nihira2020/dotnetcore_api_jwttoken/blob/master/Startup.cs) (ASP.NET configuration), [`Controllers/ProductController.cs`](https://github.com/nihira2020/dotnetcore_api_jwttoken/blob/master/Controllers/ProductController.cs) (Product endpoints), [`Controllers/UserController.cs`](https://github.com/nihira2020/dotnetcore_api_jwttoken/blob/master/Controllers/UserController.cs) (Authentication and access)
