Я смотрю на код из здесь
///
/// Returns the command that, when invoked, attempts
/// to remove this workspace from the user interface.

public ICommand CloseCommand
{
get
{
if (_closeCommand == null)
_closeCommand = new RelayCommand(param => this.OnRequestClose());
return _closeCommand;
}
}

в param => this.OnRequestClose ()
?
