If you import the module that New-TableContent is in, does it work then?

[PrzemyslawKlys]

Nope.

Thanks @PrzemyslawKlys this is a feature that we took out for performance reason, so I will mark this as a feature request to work again

So this is partially fixed. Both [alias(...)] and Set-Alias, if the script has been executed in the integrated console (i.e. with F8) then "Find References" will work (but go-to definition still does not). In order to not rely on querying the aliases in the runspace, we would need an AST way to find all the aliases instead.
