Hi all. I have small problem. In WPF apps when I use ICommand implementations on buttons (for example) I dont need bind IsEnabled property of this button to something. Its doing automaticly when CanExecute return false. But in Noesis I dont see this behavior... Maybe I'm dooing something wrong and miss something.... Or in Noesis I really need bind all IsEnabled properties to command CanExecute?

Nothing wrong on your side. Our controls are not listening to the ICommand.CanExecuteChanged event yet, so IsEnabled is not automatically updated.
Please report it in our bugtracker so you can track the development of this feature.

Stumbled to this same issue when using C++ SDK. So it's not specific to Unity or C# SDK, right ?

No, this feature is not implemented, so it is not availbale in any API.
We will solve it as soon as possible.
