Learning ASP.NET Web API (Video 29)

The video tutorial discusses the concept of versioning in web APIs, emphasizing its importance due to the constant changes in requirements and technology. It outlines the challenges of maintaining backward compatibility and presents three main approaches to versioning: URL path, custom request header, and accept header. Each method's pros and cons are analyzed, with a focus on how they affect client interaction and API semantics. The video concludes by suggesting that the choice of versioning strategy should depend on specific requirements and client control.

Why is versioning important for web APIs?

• To ensure backward compatibility and avoid breaking client code

• To increase the speed of the API

• To reduce the cost of API maintenance

• To improve the security of the API

Which of the following is a disadvantage of URL path versioning?

• It does not allow for backward compatibility

• It is not supported by all web browsers

• It requires changes in the URL for each new version

• It increases the complexity of the API

What is a potential drawback of using custom request headers for versioning?

• It is not supported by RESTful services

• It requires changes in the URL

• It is not a semantic way to describe the resource

• It does not allow for content negotiation

How does the Accept header method benefit API versioning?

• It complicates the API design

• It allows for content negotiation without changing the URL

• It requires additional custom headers

• It is only suitable for private APIs

Which versioning method is becoming more popular for public APIs?

• Using the Accept header

• URL path versioning

• Custom request header versioning

• URL query string versioning
