Since the question appears to be only incidentally concerning networking, I have moved it to general programming.

static types cannot be used as return types [/quote]

This is a C# error message about the code syntax.
It looks like the "Neoforce" library is not designed to work in the environment you're trying to use it.

The errors you are getting point to fundamental weaknesses in your current understanding of the language. This indicates that your chosen project is well above the level of your abilities at this time. This is the programming equivalent of trying to run before you can walk.

I would recommend you put this project on hold for the time being, and go back to learning the core language. Buy a good book, or borrow one from your local library, and go through it, paying particular attention to completing all the exercises at the end of each chapter.

Once you've built up your skills, then you can try to tackle a few small games first. Building games like this will get your learning about how to design larger and larger programs, which is another skill that you'll need. Designing a simple game like Pong is quite different from something like Mario or Doom.

I wouldn't recommend trying a networked game as one of your first few projects, there are a lot of skills you will need to be able to make such a game. Your first networked program should probably be something like a chat client or a simple HTTP server, something to familiarise yourself with the concepts and how to debug issues.

This is true for all technologies. If you aren't comfortable using a database make a separate project to get familiar - for example implement some simple DVD or Book cataloguing software. If you have never made a game using Neoforce then write something small using it to ensure you understand what it gives you and how to use it.

Finally, when you've built up your core language skills, your project design skills and your skills in the specific technologies you want to use, then return to your current project.

making network connection with form i can make but with neoforce not
becouse the mettod invoke don´t exist in neoforce project

I understand your problem. The code will not be the same in both cases. The fact that you appear to expect it to be, and the level of technical detail in your reply indicates you have not yet got all the necessary skills I have been talking about.

If you have been copying code from tutorials, be aware that this can make you appear to be able to do more than you actually can. Part of learning a new skill is understanding how much or little one knows - the ability to making accurate introspective judgements. In my experience as a developer, and as someone who has seen people at all levels of skill here on gamedev.net, I am fairly certain of my evaluation of your current ability.

If you can tell me what you have tried in enough detail to prove my evaluation wrong (for example, perhaps the language barrier is interfering with my perception), I will certainly try to help you. But I can not meaningfully help you with this specific problem right now, because the real cause of this problem is you being out of your depth.
