Description and solution of below given error

Service does not conform to WS-I Basic Profile v1.1. Please examine 
each of the normative statement violations below. To turn off 
conformance check set the ConformanceClaims property on corresponding 
WebServiceBinding attribute to WsiClaims.None. R2304: Operation name 
overloading in a wsdl:portType is disallowed by the Profile. 
A wsdl:portType in a DESCRIPTION MUST have operations with distinct 
values for their name attributes. Note that this requirement applies 
only to the wsdl:operations within a given wsdl:portType. 
A wsdl:portType may have wsdl:operations with names that are the same 
as those found in other wsdl:portTypes.  -  Operation 'Add' on portType 
'myWebServSoap' from namespace 'http://tempuri.org/'. To make 
service conformant please make sure that all web methods belonging to 
the same binding have unique names.

This error will come while you try to overload methods in webservice.

Solution of this error is below: 




First you have to use the MessageName for using Overloading the Webservice.

 

Like if you are using the Two add methods the we will have to write MessageName with second method. This is not sufficient to overloading. You need to write

[WebServiceBinding(ConformsTo = WsiProfiles.None)]


After this, service will properly run.

We also can use the Description with Webservice

[WebMethod]
 public int Add(int a, int b)
{
  return a + b; 
} 

[WebMethod(MessageName="abc",Description="Using at adding 4 Parameters")]
 public int Add(int a, int b,int c,int d)
{
  return a + b + c+d;
}
