[X# 3] xsi is broken

[fforay]

Start X#3 XSI with dotnet xsi.dll

Try to print a string/constant with
? "Hello"

Error message is:
error XS0234: The type or namespace name 'Console' does not exist in the namespace 'System' (are you missing an assembly reference?)
Script(1,1): error XS0234: The type or namespace name 'Console' does not exist in the namespace 'System' (are you missing an assembly reference?)

When trying to declare something, the trouble is the same:
LOCAL x as int
error XS0234: The type or namespace name 'Console' does not exist in the namespace 'System' (are you missing an assembly reference?)

This only happens with the NetCore version of xsi.dll
The Framework version works fine
In the netcore version you will have to load a reference to system dll first:
#r "system.dll"
Then it works
