WPF: the type or namespace name "icommand" cannot be found (is the using command or assembly reference missing ?)

However, you will find that vs prompts an error: "the type or namespace name" icommand "cannot be found (is the using command or assembly reference missing ?) ".

Solution: Add presentaitioncore. dll reference.
