Variable links problem in TwinCAT 3 on windows 10

I am using TwinCAT 3 on Windows 10, and create a PLC project in visual studio 2013 shell(isolated). When I try to link an output variable to an input variable by “Change Link”, there is always no avaible variable to be linked.

The pop-up window is as following: Attach Variable pop-up window

What may be the problem?

If you want to link the variable with a project instance variable you need to uncheck "exclude same image" otherwise if you want to link the variable with a hardware IO you need to have an IO tree attached to your Ethercat Master.
