Lots of Intellisense (not build) errors in VS2022? (Read 2102 times)

	I've noticed that VS2022 is giving me LOTS of Intellisense errors (45 at the latest count). However, if I select 'Build Only' instead of 'Build+Intellisense', all the errors go away. Even with the Intellisense errors turned on, the project builds and runs OK. I have tried addressing many of these errors, but they aren't particularly fixable. For instance, Intellisense doesn't like the ellipsis mark (3 dots) in the line ' case -100 ... - 67:', and it apparently doesn't like enum identifiers that are used without the full name, i.e. 'VL53L0X_READYCHECK' as opposed to 'VL53L0X_REQUEST::VL53L0X_READYCHECK', even though the hover tag shows the full identifier correctly. Researching this issue on the inet shows lots of complaints about Intellisense errors when using VS2022, but none of the proposed fixes (including removing the .vs folder) seem to work (or seem irrelevant) for me. Anyone else having this problem - and maybe found a way to fix it? If not, has anyone successfully downgraded back to VS2019? TIA, Frank

	Thanks for the report. Can you attach the full build log from your project with the verbose settings enabled shown at the top of the page?

	Here's the build log, with 'verbose' and 'build properties' enabled

	Thanks for the logs, could you provide a small snippet which demonstrates the main two issues highlighted so we can investigate further?

	Hmm, it's a pretty big program, but I'll work on that. I assume you need it to be a stand-alone running sketch, correct? Frank

	If possible it would be appreciated, and we will be able to advise what can be done more easily.

	OK, here's a small stand-alone sketch that shows two of the most prevalent Intellisense errors. I defined a set of enums and then defined a variable of that type. Intellisense insists that I use the full name for the enum, even though it compiles correctly. Then I wrote a 'switch' statement using the enum variable, and did a case using ellipsis. Intellisense flags this as an error even though it compiles correctly. If only build errors are shown, there are zero errors, but with 'build + intellisense', there are LOTS. Full program folder and verbose compile output attached as a ZIP file. Hope this helps. Frank

	We will take a close look. One possibly incorrect assumption is that it might be the "..." gcc args causing the issue. The current "project type" that we use for intellisense in VS isn't great for underlying gcc code. nb: We will shortly be releasing support for a new "project type" that uses the real gcc code system, instead of a variation of std. vs c++ projects. (It will be a simple intellisense switch over for existing project code, doesn't affect the build/upload etc.)

	Thanks Tim, for taking the time to look at this. However, please don't go full OCD on this, as it is just an annoyance, not something that should take your valuable time away from real work

	I just updated to 22.09.05.7 - does this version have the new "project type" you were mentioning? If so, how do I go about shifting my project(s) over to this? TIA, Frank

	No not yet, it will be in the release notes when it is available.
