Welcome to the Product Manager application:

This application was made conseidering the following request sent via email by Rodrigo Guerreiro from k2:

" Project WebAPI - . Net Core 2.x

• Criação de 2 entidades: Categoria (id, nome) e Produto (id, nome, categoria)
• Deve ser utilizado SQL server e Entity framework core
• Pelo menos utilizar 2 "design patterns"
• Disponibilizar projecto via GIT
• Caso faça sentido, criar documentação com as principais opções tomadas"

As such, I did a simple product and category manager which I called "ProductManager". I tried to do a clean and understandable application following the SOLID principles of object oriented applications.

Before you try to use this API, make sure you set the environment variable: CONNECTION_STRING_PRODUCTMANAGER with your connection string.

As you run the Products.Api webapplication, you will come across a swagger page from which you can check the 2 available controllers and all endpoints available.

Now regarding the solution itself:

• As requested, I used 2 design patterns a mapper to map the dtos to view models and vice versa, and a factory to create contexts so that we close the connection when not in use.
• I created the exact entities requested with the required fields.

Testing:

• Due to the lack of time the tests might not cover the hole solution at this stage although, I did a mock to emulate the database and created a base test which can be used to easily test diferent services. This means that you can easily add more tests to all the services you which to add or, if you which, you can add specific tests to specific services.

If you have sugestions/constructive constructive criticism please contact me, I'm always interested in improving.
