Remarks

Use the MessageParameterAttribute to control the name of the parameter or the return value. This attribute has no effect if the parameters are marked by the MessageContractAttribute attribute.

Note:
The value of the parameter names in the operation signature are part of the contract and are case sensitive. Use this attribute when you must distinguish between the local parameter name and the metadata that describes the operation for client applications.
