Hi Metro156,<br />
<br />
here you go ...<br />
<br />
WCF is basically &quot;ASMX on stereoids&quot; - it can be all that ASMX could - plus a lot more!.<br />
<br />
ASMX is:<br />
<br />
easy and simple to write and configure<br />
only available in IIS<br />
only callable from HTTP<br />
WCF can be:<br />
<br />
hosted in IIS, a Windows Service, a Winforms application, a console app - you have total freedom<br />
used with HTTP (REST and SOAP), TCP/IP, MSMQ and many more protocols<br />
<br />
<br />
In short: WCF is here to replace ASMX fully.

Hi Metro156,

here you go ...

WCF is basically "ASMX on stereoids" - it can be all that ASMX could - plus a lot more!.

ASMX is:

easy and simple to write and configure
only available in IIS
only callable from HTTP
WCF can be:

hosted in IIS, a Windows Service, a Winforms application, a console app - you have total freedom
used with HTTP (REST and SOAP), TCP/IP, MSMQ and many more protocols


In short: WCF is here to replace ASMX fully.

<div class="content wysiwyg-content">
When someone says <b>XML Web Service</b>, that could mean <b>ASMX</b> &nbsp;or <b>WCF</b> correct?<br />
<br />
Because both send &nbsp;data back and forth in the XML format within a SOAP envelope, correct?

When someone says XML Web Service, that could mean ASMX  or WCF correct?

Because both send  data back and forth in the XML format within a SOAP envelope, correct?

XML Web Services

A Web service is a method of communication between two electronic devices over a network. It is a software function provided at a network address over the Web with the service always on as in the concept of utility computing. A web service has an interface described in Web Services Description Language (WSDL). Other systems interact with the Web service in a manner prescribed by its description using SOAP (Simple Object Access Protocol) messages. There are two major classes of Web services: REST-compliant web services, and Arbitrary web services.

Web Services

Simple Object Access Protocol (SOAP) is a protocol specification for exchanging structured information in the implementation of web services. It uses the XML Information Set for its message format and uses other protocols, notably Hypertext Transfer Protocol (HTTP) and the Simple Mail Transfer Protocol (SMTP) for message transmission.
