Created by Microsoft with.NET, WCF (Windows Communication Foundation), provides platforms to build secure and reliable service. While Web API framework is used to make HTTP service and is used to create complete REST service.
In this article, we will discuss the basic differences between Web API and WCF:
Representational State Transfer (REST)
Rest is the architecture design pattern, used to build and create Web Services. These architecture design patterns are used by the Web API to build web services. Web API utilizes POST, DEL, PUT and GET verbs for the communication purposes to the client and is fully REST supported.
Simple Object Access Protocol [SOAP]
Invented by Microsoft, SOAP is a protocol, which creates an organized format information or message, which can be transferred to the internet. It uses XML format and is the main foundation of WCF. While, WSDL is the file created by Web Service, and it is basically utilized by the client to find out the methods that are available on the service.
HTTP response/requests are normally smaller as compared to SOP response/request, because, RESTful services use HTTP protocol to get access to the client. So, Web API is the best option to access client, especially for low bandwidth devices/mobile devices.
When we compare WCF vs Web API, both of these frameworks provide security standards, Web API utilizes web standard security, for example, fundamental validation, token verification and for more intricate, for example, OAuth; Web API gives greater adaptability. At that point utilize SOAP when you will validate with outside administrations, for example, google, facebook, and so forth.
But, WCF service gives us high-level security system which gives enterprise-level security. It utilizes WS-I standard to give secure service.
Along these lines, we can’t choose which is superior to the next. Be that as it may, I would focus on the two points. Initially, WCF is best if you want to create service on various platform and Web API is best if you are going to create internet service for different platforms.
