Web Methods

Attaching the WebMethod attribute to a Public method indicates that you want the method exposed as part of the XML Web service. The WebMethod attribute tells .NET that a particular public method should be exposed as a web-callable method. The WebMethod attribute has six associated properties to document and change the behavior of your web method. They are:

1.  Description

2.  MessageName

3.  EnableSession

4.  CacheDuration

5.  TransactionOption

6.  BufferResponse

The first two properties are used to document a web method, while the others affect its behavior.
