This may help you with intellisense and possibly other Visual Studio integration problems:
Sometimes the fix is as simple as doing Assets → Open C# Project from Unity. Other times it requires more.
Other times it requires you also nuke the userprefs and .vsconfig and other crufty low-value high-hassle files that Visual Studio tends to slowly damage over time, then try the above trick.
Barring all that, move on to other ideas:
Also, try update the package inside of Unity: Window → Package Manager → Search for Visual Studio Editor → Press the Update button
Depending on flavor and version of Visual Studio, it may also have an installation step that you perform within the actual Visual Studio. This step seems finicky at best and may require multiple openings of VS before it comes up.
Update: The VSCode extension has been deprecated and abandoned:
Update: the VSCode integration is back… maybe!?
There may be a community fork available that is receiving updates.
Also, this: No suggestions in Vscode - Unity Engine - Unity Discussions
Recently (July 2023) I worked on a Windows11 system that required a Microsoft component to be installed from within Visual Studio before it would work properly with all the OTHER software installed under Unity. I have no documentation on that process as I have only seen it once and it surprised me as well.
THANK YOU!!
I will try all of the solutions you provided and hopefully they will work!!
visual studio is not a “normal” app, it has a lot of places it takes the data from and if one of those pieces is missing it will fail to work.
If your IT department added custom rules to the system it will be hard to figure out what VS can’t access. I suggest maybe finding a dedicated VS forum.
Also shot in the dark
try the VS Code version
Thanks
It is has worked for 12 years so hopefully we can continue
We use VS code for web design so that is an option also
Thanks
