This is a general problem that started with 17.5: intellisense, renaming, underlining all failing; GoToDeclaration etc all much slower. Possibly related to Boost (https://developercommunity.visualstudio.com/t/VS2022-175-C-Intellisense-fails-on-i/10291033?q=intellisense&sort=newest) though difficult to see why such a library should cause such widespread IDE problems. I guess Intellisense relies on an incremental compilation? Unfortunately, 17.5.1 didn't fix any of the problem

I've been having this exact problem with a C++ solution since updating to 17.5.

I confirm the same problem for me. Using Boost 1.72, 1.76, 1.81 in different projects via nuget packages from nuget.org. IntelliSense quickly fails on parsing boost headers, and all functionality becomes broken, making VS totally unusable.

Had to rollback to VS2019

Hello everyone, please update your VS to the latest version with Visual Studio Installer and check if it works normally.

Same problem here. Not using script manager.
intellisense (eg pressing .) doesn't work on old OR new projects.
I've never heard of 'boost libraries', I'm probably not using them? I do C# 6 MVC and Blazor Server. It's broken in both.
Definitely looks like a problem with the latest update and needs fixing urgently!

I've been having this problem across 2 different machines for a few months, always updating to latest VS, including right now.Latest update still hasn't fixed it. Intellisense still not working.

I'm running 17.7.4 (which is up to date today) and intellisense is not working either. When will this be fixed?????

I also have issues with Intellisense in the current version of Visual Studio 2022 (17.8.3). It does not display parameters from a '.razor' added after linking to another page, in addition to other behaviors that degrade productivity.

well, well, dear Microsoft! We've updated to latest version and now InteliSense down entirely.. please advise our effectiveness dropped dramatically..

https://learn.microsoft.com/en-us/answers/questions/1185434/how-to-fix-visual-studio-2022-17-5-intellisense-no

While we do use Boost, we've got none of its files opened etc.

Parsing of any file is so slow it seems to take minutes for a single file and then InteliSense is not available even for language intrinsic constructs!

well, what we did was - we've rolled back to previous version. Fortunately such a feature was included in 17.4 right, Microsoft? Just in time..

I confirm the problem. The work is hell when Intellisense not working.

Completely the same sympthoms as the colleagues have reported above with the screenshots.

Dear Micrsoft. Could you please stop asking the same questions and JUST open VS2022, add Boost to the project and reproduce the problem??

I solved it ( at least for now ) by upgrading from version 17.5 to 17.5.3

You may be experiencing this problem if you are using ScriptManager to add bootstrap to your site. Try adding bootstrap as a link in the <head> of the page or masterpage.

example: <link href="./Content/bootstrap.css" rel="stylesheet" type="text/css" />

I'm not using ScriptManager or bootstrap. I just upgraded to 17.6. Intellisense helper not showing anymore. "Intellicode" is working.

I found this here which worked for me:

I was able to resolve this by going to Tools > Options > Text Editor > All Languages > General and enabling the Statement Completion > Auto List Members. For some reason unknown to me, mine got turned to the intermediate state.

The same problem is in editing XAML, WPF. There is none any bootstrap in xaml. Does exist alternative to VS?
