Ultimate ASP.NET 5 Web API Development Guide - Implementing API Versioning

The video tutorial covers the concept of API versioning, explaining its importance in maintaining client compatibility when APIs undergo breaking changes. It demonstrates how to implement versioning using the ASP.NET Core MVC versioning package, configure default versions, and set up API version readers. The tutorial also shows how to test versioning using query strings and headers, and explores advanced techniques like root modification and using multiple controllers for different API versions.

Why is API versioning crucial in API development?

• To handle breaking changes without affecting clients

• To enhance security features

• To reduce server load

• To improve API performance

Which package is used for API versioning in ASP.NET Core?

• aspnetcore.mvc.versioning

• aspnetcore.mvc.security

• aspnetcore.mvc.performance

• aspnetcore.mvc.logging

What is the purpose of setting a default API version?

• To enhance data encryption

• To ensure all requests are rejected

• To provide a fallback version when none is specified

• To increase API response time

How can API versions be specified in requests?

• Through cookies

• Through query strings and headers

• Only through query strings

• Only through headers

What is the advantage of specifying API version in the header?

• It reduces server load

• It keeps the request URI clean

• It increases security

• It speeds up the request

What happens if an unsupported API version is requested?

• The request is ignored

• The request is processed with a random version

• The request is rejected with an error

• The request is processed with the latest version

What does the 'deprecated' property indicate in API versioning?

• The API version is the latest

• The API is temporarily unavailable

• The API is no longer functional

• The API version is outdated but still accessible

How can different versions of an API controller be managed?

• By creating separate controller classes for each version

• By using different server instances

• By changing the database schema

• By using different programming languages

What role does Swagger play in API versioning?

• It enhances API performance

• It allows testing of different API versions

• It manages server load

• It provides security features

Why might you create a new controller class for a different API version?

• To enhance security

• To reduce code complexity

• To handle different functionalities for each version

• To improve server performance
