I've tried today to update installation of FNC packages into Visual Studio Code, downloading last updates of 18.Dec.23 (WebCore VSC auto updated to 2.3.7064 few days ago).
I received install errors (missing units) when using TMSFNCCoreVSCReg.zip v3.1.3.3 (zip file size is 1.1MB - DEC.23).
Everything is fine using TMSFNCCoreVSCReg.zip v3.1.3.2 (zip file size is 2.8MB - NOV.23).
I have not tracked which .pas files were missing... but just switched back to the previous version of the FNCCoreVSC and did again the installations of additional packages (like cloudpack and websocket).
I've seen right now that there is a new VSC TMS WebCore release v2.3.7106 available... I will retry installation in the afternoon with the latest packages and keep you updated.
