WebInvoke Method=“POST” or "GET" for a REST Service on WCF

When should use post vs get? in a REST service on WCF?, below is my interface 

       [OperationContract]
       [WebInvoke(Method = "POST", BodyStyle = WebMessageBodyStyle.Wrapped, ResponseFormat = WebMessageFormat.Json)]
       string DoLodge(string Id, Lodge value);

       [OperationContract]
       [WebInvoke(Method = "POST", BodyStyle = WebMessageBodyStyle.Wrapped, ResponseFormat = WebMessageFormat.Json)]
       LodgeLevel[] GetLodgeLevels(string Id);

       [OperationContract]
       [WebInvoke(Method = "POST", BodyStyle = WebMessageBodyStyle.Wrapped, ResponseFormat = WebMessageFormat.Json)]
       long GetLodgeCount(string Id);

But in C#, you receive a response in GET. so the complete answer will be, GET should be used when retrieving an object from the server and used when sending an update back from the server.

POST should be used when sending an update back to the server.

GET should be used when retrieving an object from the server.

GET: Get a collection of entries (as a feed document) or a single entry (as an entry document).

POST: Create a new entry from an entry document.

PUT: Update an existing entry with an entry document.

DELETE: Remove an entry.

POST everytime you are modifying some state on the server like database update, delete. GET for readonly fetching like database select.
