What is the difference between WCF and ASMX Web services?

The basic differences between WCF and ASMX services:- 1) ASMX services only support HTTP protocols where in WCF services supports other protocols like TCP, Namedpipes, MSMQ etc. However, WCF services can send and receive data using any format over different protocols like HTTP, HTTPS, TCP, MSMQ etc.

Why Web service is better than WCF?

Web services support only one protocol- HTTP and HTTPS during communication, but WCF supports more protocols like- HTTP, TCP, and MSMQ that can be extended for a comprehensive solution, reliable session, and transactions. It signifies WCF is more adaptable to work together for a variety of software.

Is Asmx a WCF?

WCF completely replaces ASMX web services. ASMX is the old way to do web services and WCF is the current way to do web services.

Is Web API better than WCF?

WEB API is a better choice for simpler, light weight services. WEB API can use any text format including XML and is faster than WCF. WEB API can be used to create full-blown REST Services. WEB API doesn’t require any data contracts and doesn’t require configurations to the level of WCF.

Why WCF service is used?

WCF lets you asynchronus messages transform one service endpoint to another. Windows Communication Foundation(WCF) supports multiple language & platforms. WCF Provides you a runtime environment for your services enabling you to expose CLR types as Services and to consume other Services as CLR Types.

Why do we need WCF service?

Does WCF use SOAP?

WCF services use SOAP by default, but the messages can be in any format, and conveyed by using any transport protocol like HTTP,HTTPs, WS- HTTP, TCP, Named Pipes, MSMQ, P2P(Point to Point) etc.

How do I call Asmx service from .NET core?

Right click on Connected Services folder (should appear just below your project) and select Add Connected Service. Then select “Add a WCF web service”. Put your asmx url into the URI field, set the name space and click Finish. You will now have the reference set.

Is WCF a web service?

Windows Communication Foundation (WCF) allows you to create a service that exposes a Web endpoint. Web endpoints send data by XML or JSON, there is no SOAP envelope. This topic demonstrates how to expose such an endpoint. The only way to secure a Web endpoint is to expose it through HTTPS, using transport security.

What is the difference between WCF and asmx?

While WCF service can exchange messages using any format (SOAP is default) over any transport protocol (HTTP, TCP/IP, MSMQ, NamedPipes etc). ASMX is simple but limited in many ways as compared to WCF. ASMX web services support is limited to HTTP while WCF supports HTTP, TCP, MSMQ, NamedPipes. ASMX Security is limited.

What’s the difference between WCF and ASP.NET Web Services?

ASP.NET Web services can send and receive messages using SOAP over only HTTP or HTTPS. Wcf services have a “.svc” extension. Web services have a “.asmx” extension. The svc page uses the “ServiceHost” directive. The asmx page uses the “WebService” directive. It uses DataContractSerializer in System.RunTime.Serialization namespace for serialization.

Which is webservice Directive does ASMX page use?

The asmx page uses the “WebService” directive. It uses DataContractSerializer in System.RunTime.Serialization namespace for serialization. For serialization, ASP.NET Web services are based on the XmlSerializer in System.XML.Serialization namespace.

How are ASMX services used in ASP.NET?

ASMX services simply use an https transport protocol for transferring data between a service and its clients. It does not support any other protocol. The file with an extension .asmx is accessed using an URL similar to the one shown in the above image.
