Which points to a type alias. Oddly I can't get it to reproduce in the online tool.

Version: telplin 0.4.0

The gut feeling here is that the condition defines are not taken into account.
NETSTANDARD2_0 will most likely be set for the typed tree parts and the untyped tree didn't take those into account when parsing. So, it can't resolve any symbols for the typed tree because the untyped tree didn't specify any defines.
It should at the verify least re-use the same defines in the untyped tree parsing, which is something I hope to cover with #46
