Now we can test our endpoints using Swagger. To do this, run the application by executing the following command in the terminal:

dotnet run

This will run our application. You can open your browser and navigate to https://localhost:5001/swagger/index.html to access the Swagger documentation. You should see a list of API endpoints, request and response models, and the ability to test the endpoints directly from the browser.

If your port number is different from 5001, don't worry – it will still work. The port might change depending on the type of machine you're using, but it will still achieve the same result.
