By using WCF, we can quickly build services that we can integrate into any enterprise solutions. Apart from writing entirely new functionality, we can use WCF to implement services that wrap existing applications, and connect them together in ways that were previously difficult to achieve. WCF can act as the… Continue reading
ASP.NET Web services and .NET Remoting provide a full suite of design options for cross-process and cross-plaform communication in distributed applications. In general, ASP.NET Web services provide the highest levels of interoperability with full support for WSDL and SOAP over HTTP, while .NET Remoting is designed for common language runtime… Continue reading
Asynchronous Call : Application can make a call to the Webservice and then continue todo watever oit wants to do. When the service is ready it will notify the application. Application can use BEGIN and END method to make asynchronous call to the webmethod. We can use either a WaitHandle… Continue reading
WCF Service supports both http and tcp protocol while webservice supports only http protocol. WCF Service is more flexible than web service. Web services can only be invoked by HTTP (traditional webservice with .asmx). While WCF Service or a WCF component can be invoked by any protocol (like http, tcp… Continue reading

Using System.Web.Net; HTTPWebRequest req = (HTTPWebRequest)WebRequest.Create(“www.abc.com?id=123&name=asd”); Req.getResponse();
Choosing a UDDI provider is only a matter of personal preference. All UDDI providers share the same database of information. After you make a UDDI entry in one provider, the entry propagates to all other UDDI providers within a short amount of time.
To understand the advantage of using WCF over other distributed programming models like Web Services(ASMX), .NET Remoting, Enterprise Services stack etc, let’s consider the following scenario. We have developed an application using web services. As we know web services use HTTP protocl and XML SOAP formatted messages, they are good… Continue reading
Web services are a core technology provided by the .NET Framework. By using web services, companies can more easily integrate internal applications, but they can also access services exposed by other businesses. By combining web services exposed on the Internet with internally built services, companies can create a wide variety… Continue reading
SOAP (Simple Object Access Protocol) is a simple XML-based messaging protocol to let applications exchange information over HTTP. It defines a set of rules for structuring messages that can be used for simple one-way messaging but is particularly useful for performing RPC-style (Remote Procedure Call) request-response dialogues. It is not… Continue reading
