Prefer the per-call instance mode.
Avoid a sessionful service.
If selecting
SessionMode.Requiredon the contract, always explicitly set service instancing toInstanceContextMode.PerSession.If selecting
SessionMode.NotAllowedon the contract, always configure the service instancing toInstanceContextMode.PerCall.Do not mix sessionful contracts and per-call contracts on the same service.
Avoid a singleton unless you have a natural singleton.
Use ordered delivery with a sessionful service.
Avoid instance deactivation with a sessionful service.
Avoid demarcating operations.
