Intellisense is not working as supposed in VS 2019. It can not find classes from imported namespaces:

What I have already tried is unload and reload all projects, as suggested here, but it doesn't help. I would like to navigate with F12 to selected class, but intelli sense doesn't find it.

What else can I try? I am using VS2019 16.0.4 version, community edition.

Hi, does this issue only happens to this specific project? Have you already tried to delete the hidden folder .vs? – Sara Liu - MSFT May 21 '19 at 09:16
I've closed VS2019, deleted .vs folder. Intelli sense still not working. – FrenkyB May 21 '19 at 22:04
Do you have other VS version like 2017? This issue happens in other vs version or not? If you create a new project to test it, it occurs or not? – Sara Liu - MSFT May 22 '19 at 09:37
I have VS2017. There is OK. – FrenkyB May 22 '19 at 09:40
Could you please share some sample codes? I will try to test it in my vs 2019 and check if this issue can reproduce or not. – Sara Liu - MSFT May 23 '19 at 09:06
It's from my project, it's too big to post it here. But basically all referenced classes (from other projects) are showing as non-existing / intelli sense is not working. – FrenkyB May 24 '19 at 00:05
Did you write the usings correctly and are the other projects really referenced? – Nikolaus Mar 01 '22 at 10:09
@Nikolaus - yes, they are. This error is now gone, I guess with updates to VS. – FrenkyB Mar 01 '22 at 10:19
