Learning ASP.NET Web API (Video 3)

The video discusses the evolution of RESTful services in .NET, starting with WCF 3.5 and its limitations for building RESTful services. It introduces ASP.net Web API, which was developed to address these limitations by leveraging HTTP features. The video explains the similarities and differences between ASP.net MVC and Web API, highlighting their shared programming model. It also covers the features of ASP.net Web API and its suitability for building RESTful applications, emphasizing that adherence to REST constraints is necessary for true RESTful services.

What was a major limitation of using WCF for building RESTful services?

• It did not support HTTP features like caching and content negotiation.

• It was not compatible with .NET framework.

• It only supported SOAP-based services.

• It was too expensive to implement.

What is a key difference between a web application and a REST API?

• Web applications return data, while REST APIs return full web pages.

• Web applications return full web pages, while REST APIs return only data.

• Web applications use SOAP, while REST APIs use HTTP.

• Web applications are faster than REST APIs.

Which feature is common to both ASP.NET MVC and Web API?

• They both return full web pages.

• They both require SOAP for communication.

• They both support routing and action filters.

• They both use the same internal framework.

What does ASP.NET Web API provide a platform for?

• Developing mobile operating systems.

• Writing RESTful services.

• Creating SOAP-based services.

• Building desktop applications.

What is necessary to ensure that Web API services are truly RESTful?

• Using the latest version of ASP.NET.

• Adhering to REST constraints.

• Implementing SOAP protocols.

• Utilizing only HTTP GET requests.
