Intellisense stopped working complete when using Esp32 boards.
If I start a new VisualMicro project and copy .ino code in to the empty project intellisense works.
After a build it all stops working and I get a message:Intellisense: No additional information available.
I tried to resolve it by installing the 1807_21 version but no luck.
Also edited the .vcxproj file to add the V141 PlatformToolset, that was missing, but no change.

I use:
Microsoft Visual Studio Community 2017 
Version 15.8.1
VisualStudio.15.Release/15.8.1+28010.2003
Visualmicro version 1807.26.0
on:
Windows 10 64 bit preview version Rs5 release 17738

Hi

Just to say also had this problem and with ESP8266.  Other projects worked okay and starting a new test project worked fine even copying all the code across.

So I took a copy of the code, deleted the project folder, then created a new project, which I named with the same folder name, and intellisense didn't work.

The only way I could get intellisense working was to create a new project with a different name, paste across the code, and intellisense was working again.   

Something is remembered about projects even after they've been deleted, so always worth setting up a new project but with a different name slightly so it is seen as a completely new project.

Hi,
I sent you the requested email.
Deleting the .vs folder is always the first thing I try when there are troubles with Visual Studio. 
I ended up with uninstalling Visual Studio 15.8 and reinstalling version 15.7.6
In this version all is working again.
I hope there is a solution or work around for version 15.8 .
Regards,
