Understanding the Basics of Web Services using .NETInitially the use of web was quite limited to a special group of users but with the time it has created huge impact in our day to day lives. Actually with the adoption of standards like HTTP, XML and development of web service technologies it has become simpler to create distributed applications which provide foundation to the web architecture. Web services are the software components which can be explained by WSDL(Web Services Description Language) and provide application logic which is accessible using web technology or simply Internet.
There are
some popular web services technologies like SOAP, WSDL, UDDI which can
be used for developing them. But using these standards for implementing
web services is difficult and hence there should be use higher level implementation
approaches which are familiar and easier to adopt. These implementations
include J2EE using JAX-RPC and Microsoft’s .NET platform. .NET provides
a strong foundation in building, controlling and consuming web services.
With the use of Visual Studio and .NET framework you can build, debug
and deploy high performance, reliable and secure web services using programming
language from the wide range of more than 20 available. .NET framework
also allows creating cross platform interoperable applications as it supports
WS-I BasicProfile which is a group of specifications defined in order
to meet the need of interoperability in web services and let them interact
with any another application regardless of underlying hardware and software
platform. Generally
there are three components of a web service. First is server component
which is a web service itself and resides on server. Another is a client
which requests the web service through a Web Reference. Third one is a
web service description file written in WSDL. In .NET,
a web service consists of an .ASMX file which contains a class having
web service functionality and other things related to it. Also there can
have web services which reference to any external class for managing the
application logic in an external .ASMX file. First type
of web services is also called self contained or in other words, web services
in .NET are called self contained when web service header and class code
are present in a single ASMX file. Another type
is of web services which have a web service header only and for actual
class code they reference to an external class. You can use HTTP GET operation
and HTTP POST operation for calling a web service in .NET but the standard
way to do so is the use of SOAP which allows transferring complex objects
and data too.
