trying to implement code to submit score, below code is from your tutorial and gives errors on the highlighted piece of code.
Assets/AddScore.cs(24,41): error CS1519: Unexpected symbol `(' in class, struct, or interface member declaration
so i am not sure if it is my mistake or the code in the tutorial.
There appears to be a lot of errors in the code snippets that are there for unity c# and the getting started instructions miss out the fact you need to use namespaces in the headers, plus there is'nt a list of services required.
scoreBoardService.SaveUserScore(gameName, userName, gameScore, new UnityCallBack());
