Visual Studio Intellisense not working
Jan 17th, 2026 at 3:07pm
Print Post  
I have two computers. Everything works on one, but not on the other. I can compile, but none of the nice features in Visual Studio seem to work - color highlighting, code completion, Go To Definition, etc.

I don't see an option for an attachment, so I have emailed my Build Properties content.

Any help is appreciated.

Thanks for the report and log.

Would it be possible to attach a log from your working machine as well for the same board selection just for us to compare?

It may be the board package is sensitive to the Solution Configuration (ARM or ARM64) but the log will help us make more accurate suggestions.
