Normally, a WCF service will use SOAP, but if you build a REST service, clients will be accessing your service with a different architectural style (calls, serialization like JSON, etc.). Exposing a WCF service with both SOAP and REST endpoints, requires just a few updates to the codebase and configuration.

Servlets are API which is simple and provides capabilities to write server side components. Web Service uses ServletContainer class which is again a Servlet class, which handles the request in clean and structured way. The REST stands for REpresentational STateless Protocol. Here the request won't store any data.

Windows Communication Foundation (WCF) is a framework for building service-oriented applications. Using WCF, you can send data as asynchronous messages from one service endpoint to another. A service endpoint can be part of a continuously available service hosted by IIS, or it can be a service hosted in an application.

ASMX provides the ability to build web services that send messages using the Simple Object Access Protocol (SOAP). SOAP is a platform-independent and language-independent protocol for building and accessing web services. ... They only need to understand how to send and receive SOAP messages.

REST APIs use a uniform interface, which helps to decouple the client and service implementations. For REST APIs built on HTTP, the uniform interface includes using standard HTTP verbs to perform operations on resources. The most common operations are GET, POST, PUT, PATCH, and DELETE.

Add Service Reference in Visual Studio With the service running, right click the project that will contain the WCF client proxy and select Add > Service Reference. In the Add Service Reference Dialog, type in the URL to the service you want to call and click the Go button.

SOAP API, on the other hand, has an official standard because it is a protocol. REST APIs uses multiple standards like HTTP, JSON, URL, and XML while SOAP APIs is largely based on HTTP and XML. ... SOAP API defines too many standards, and its implementer implements the things in a standard way only.

To debug a WCF service in visual studio 2010, go to Debug -> Attach to Process. Check "Show processes from all users", and choose w3p.exe if you are using IIS, or the name of the application if not. Put in a breakpoint, make the call, and then you can then start debugging.

SVC file), just set the address of the endpoint to a relative URI and make sure that your Visual Studio or wsdl.exe generated client specifies the endpoint's name in its constructor. See also the MSDN article Multiple Endpoints. You can have multiple endpoints defined either on the server, or the client.

WSDL vs WADL. WSDL The Web Service Description Language (WSDL) is an XML vocabulary used to describe SOAP-based web services. ... WADL The Web Application Description Language (WADL) is an XML vocabulary used to describe RESTful web services.

When writing new code, you should always use a Service Reference simply because it is more flexible and future-proof. The service reference is the newer interface for adding references to all manner of WCF services (they may not be web services) whereas Web reference is specifically concerned with ASMX web references.

Although REST proved to be much easier to implement than other comms (notably the XML-based SOAP), it has an inherent disadvantage in that it is synchronous in nature, rather than asynchronous. “A client sends a request, the server sends a response,” Roper said, describing how REST works.

neutrality (SOAP can operate over any protocol such as HTTP, SMTP, TCP, UDP)

The WSDL specification provides an XML format for documents for this purpose. ... WSDL is often used in combination with SOAP and an XML Schema to provide Web services over the Internet. A client program connecting to a Web service can read the WSDL file to determine what operations are available on the server.

Services − WCF supports a robust security, trustworthy messaging, transaction and interoperability, while a web service only supports security services. Serializer − WCF Supports DataContract serializer by employing System. Runtime. Serialization, whereas a web service supports XML serializer by making use of System.

HTTP is a communications protocol that transports messages over a network. SOAP is a protocol to exchange XML-based messages that can use HTTP to transport those messages. Rest is a protocol to exchange any(XML or JSON) messages that can use HTTP to transport those messages.
