System.IO.DirectoryNotFoundException: error

Hello, I am trying to build a simple NodeMCU 1.0 project in VisualStudio and I can't get past the following error.
System.IO.DirectoryNotFoundException: Could not find a part of the path \libraries'.

The folder \libraries does not exist in the path ..\esp8266\2.7.1\
I also get multiple E1696 intellisense errors.

Attached is the verbose output log file

-TIA
John

Thanks for the report, it sounds like the core is not fully installed for some reason if the libraries folder is missing at that location.

Could you try removing the esp8266 v2.7.1 platform, and then install it again?
(Alternatively upgrade it to the latest esp8266 core)

Ultimately this worked.  For some reason the newest version listed in VM was only 2.71. Removing and reinstalling did nothing.  Back in Arduino I found the additional board manager URLs field was cleared.  I re-entered https://arduino.esp8266.com/stable/package_esp8266com_index.json and went back to VM and 2.7.4 was now listed.  Installed and now seems to be good.  Going to test some of my other applications now.

Thank you!
