It's no exaggeration to say that Web services are revolutionizing application-to-application communication. Web services are already being used extensively in corporate intranet environments and are making their way into commercial use, too.

Web Services exchange XML messages. Most of today's Web Service toolkits do their best to hide this fact from developers, by exposing a Web Service's behavior as method invocations against objects instead.

XML and HTTP are cross-platform technologies especially suited for building applications that can communicate with each other over the Internet, regardless of the platform they are running on. Web Services in the Microsoft .NET Framework make it easy to write components that communicate using HTTP GET, HTTP POST, and SOAP. An understanding of these concepts, along with knowledge of synchronous and asynchronous operations, security, state management, and the management of proxies by the .NET Framework is essential in building these applications. This article has been adapted from David Platt's upcoming book introducing the Microsoft .NET Platform to be published by Microsoft Press in Spring 2000.

Do we have any Web Services Testing tools in .net. i mean using that tool i should able to know that web service is working or not and which methods or services exposing to the client app.
I am consuming an ASP.Net webservice from a simple .Net application byadding a web reference. However when I invoke the web method, we see acouple of soap error entries in the application event log with theresult that the http request is not successfully completed.
We even tried to invoke the web method directly from the asmx page inIE providing in the required parameters. We still get the same errors.
Please note this problem is intermittent and does not happendeverytime.
The following are the event log entries:
Soap error: XML Parser failed at linenumber 0, lineposition 0, reasonis: The download of the specified resource has failed.Soap error: Soap client is not initialized.Soap error: One of the parameters supplied is invalid..Soap error: Loading of the WSDL file failed.
Sometimes we get a little different kind of event log entries as givenbelow:
aspnet_wp.exe (PID: 2228) stopped unexpectedly.Soap error: One of the parameters supplied is invalid..
Soap error: Loading of the WSDL file failed.
Soap error: XML Parser failed at linenumber 0, lineposition 0, reasonis:The system cannot locate the object specified.
We fail to understand as to where is the problem. We can easily browseto the wsdl file successful
