Answer 1

have you tried re-installing Visual Studio, it might solve your problem?

Answer 2

I had multiple NuGet Packages that were not used at all.

From this answer: https://stackoverflow.com/a/36645281/12485722

I have downloaded ReSharper Ultimate 10.1 EAP 3 for 30 days trial and Remove Unused References which also supports NuGet references as well.

Now the IntelliSense is up and running again.
