I am pretty sure I already know the answer to this, but now with PB 2021 is out I shall give it a hail Mary...
Given: PB Classic desktop app, has to consume multiple .NET classes for external communications and other purposes.
All .NET classes have properties, which are also .NET classes (not simple data types).
PB .NET DLL importer cannot import properties, which are not simple data types. Without this capability the whole thing is useless for us - the pre-flood OLE works better.
Question: am I missing the way this capability is supported or it is not supported and we are stuck with OLEs until the end of times? I believe I raised this issue first in 2019 (year, not the version).
