FireDAC with Web Core

I have just started investigating TMS Web. 
I have been trying to use a FireDAC component in a TMS Web project but the project fails to compile complaining that it cannot find FireDAC.Stan.Intf, FireDAC.Stan.Option, etc...

 Maybe a look at TMS xData could give you an overview how to deal with this challenge !
