Error : Operation 'Operation' of contract 'Contract' specifies multiple request body parameters to be serialized without any wrapper elements.

During working with WCF Service, multiple scenarios were there for me. I completed POST scenario with one argument which works fine for me. But, POST scenario with more than one argument leads me to following error 

"Operation 'Operation' of contract 'Contract'
specifies multiple request body parameters to be serialized without any wrapper
elements. At most one body parameter can be serialized without wrapper elements. Either remove the extra body parameters or set the BodyStyle property on the WebGetAttribute/WebInvokeAttribute to Wrapped."

after some googling i got to know, "WCF doesn't support more than one parameter with bare body, if you need pass several parameters in one post method operation, then we need set the BodyStyle to Wrapped."

I added BodyStyle attribute to my contract to Wrapped help me out to working condition for my method.
Following are some links which i find useful for me for this error.
(1) Why cant I use two arguments in a WCF REST POST method?

(2) WCF Service Proxy throws exception when more than one parameter is used in [OperationContract] method

(3) WebInvokeAttribute.BodyStyle Property

(4) WebMessageBodyStyle Enumeration
