Ultimate ASP.NET 5 Web API Development Guide - Set Up Data Transfer Objects and Refactor Controller

The video tutorial covers handling hotel operations by creating classes and setting validation rules. It discusses the use of inheritance and granularity in class design, followed by refactoring code and using Auto Mapper for efficient data handling. The tutorial also demonstrates implementing CRUD operations with mapping and concludes with testing the API and reviewing documentation.

What fields are necessary when creating a hotel?

• ID, Name, Address, Country ID

• Name, Address, Rating, Country ID

• Name, ID, Rating, Country ID

• Address, Rating, ID, Country ID

Which field is not mandatory when creating a hotel?

• Address

• Rating

• Name

• Country ID

What is the purpose of making a field nullable?

• To allow it to accept no value

• To make it a required field

• To ensure it always has a default value

• To increase its maximum value

Why might you choose not to create a separate class for updating hotel details?

• Because the base class already covers necessary fields

• Because it is not supported by the framework

• Because it requires too much code

• Because the update operation is not needed

What should be considered when deciding the level of granularity for class creation?

• The size of the database

• The version of the programming language

• The specific requirements of the situation

• The number of developers on the team

What is the role of AutoMapper in the hotel's controller?

• To handle database connections

• To map data types between layers

• To validate user input

• To generate API documentation

How does AutoMapper improve code readability?

• By reducing the number of lines of code

• By removing all validation rules

• By increasing the number of comments

• By adding more complex logic

What is a potential benefit of mapping a hotel object back to a hotel detail?

• To make the code more complex

• To control the amount of information returned

• To simplify the database schema

• To increase the size of the response

Why is consistency important in API responses?

• To increase the number of API users

• To reduce the number of API endpoints

• To make the API easier to use and understand

• To ensure faster database queries

What operation does not require refactoring according to the transcript?

• Get

• Update

• Create

• Delete
