After updating to VS2019 v. 16.4.5 the using statements in my .cshml.cs files are grayed out and Intellisense doesn't work. What's happening?  How can I get around this?

Are all or some of the 'using' statements grayed- out?

All using statements are grayed out. I do get some limited Intellisense, but I cannot get to identifier definitions. Thanks.

You have Visual Stuido issues not .NET Core issues. which can be addressed at the below forum.

I shutdown my machine overnight and started it this morning.  When I tried to start VS2019, it failed to start and displayed a message box which said, in effect, an update was in progress.  (I don't remember specifically the message.)  I allowed it to complete and the using statements are now active and Intellisense appears to be fully functional.  I haven't a clue what was going on.  The version number for VS2019 is unchanged.

I have seen similar issues where intellisense looses its intelligence all together for any entire file.

Or, when I do preview changes before publishing the squiggle generator is out of whack.

Sometimes Visual Studio flakes out running some process.  Closing and reopening Visual Studio fixes the editor code  helpers, at least, for me.
