Solution 1

That's simply because you have not implemented a method called Invoke. I guess that is intentional as you seem to think your class client inherits Control which has a method called Invoke.
So you'll have to either implement Invoke yourself or inherit from Control[^].
The same goes for Form1.client.InvokeRequired
