finally i solve the problem
class in the world and where we will spend the whole game ie where are the monsters, npc players and even my divuda is if I have to pass this code to xna or simply can stay like this
create a connection client
Your previous post seems to indicate you have solved the problem, so it isn't clear what help you now require. Can you elaborate on your current issue? If there is an error, post it. If the problem is with the runtime behaviour, can you explain what you are actually seeing versus what you expect to see?
If possible, post a minimal code example that demonstrates the error or behaviour. Try to isolate the problem from the rest of your code.

i have the login and world like this public sealed partial class World : Window
i my question is the world can be public sealed partial class World : Window your have to be a game component
if yes you pass the windows to a game component
i my question is the world can be public sealed partial class World : Window your have to be a game component
