IntelliSense marks all callables in VS 2019 as "already exists"

[tcNickolas]

Describe the bug

When I open a project in VS 2019, IntelliSense often errorneously underlines all callables with red squiggles, claiming "QS6001 A function or operation already exists". The build passes (correctly), since these callables are defined only once.

To Reproduce

I cannot pinpoint what exactly causes this; it often happens if I've worked with this project before, and deleting bin and obj folders before restarting VS sometimes helps, but right now I'm looking at a restarted VS for which it didn't. QDK version in the project not matching extension version might factor in

Expected behavior

IntelliSense only reporting callables that are indeed duplicates.

System information

• Extension 0.20.2110.171573
• .NET Core 3.1.415
• VS 16.11.5

This is tricky without repro steps - I haven't seen this, but something similar is a known issue when target packages are used. You are not using target packages, are you?

I'm using regular kata projects, and I get this behavior on multiple ones - just opened the TruthTables kata from a fresh repository clone (so no old builds of mismatched versions hanging around) and I'm getting this again.
