Steps to Reproduce:

1. create a new console application (.net 6)
2. import a nuget package (NAudio in my case, but that doesn't matter)
3. get a reference to an object having an event (an MMDevice in my case, but that doesn't matter either)
4. try to let VS generate the event handler:
   let's say the variable name is myVariable, and the event is MyEvent:

myVariable.MyEvent +=

now, a tooltip tells you to hit the TAB key to generate the proper event handler
5. Hit the TAB key
6. observe that nothing happens

Expected Behavior:
a proper event handler should be generated
Actual Behavior:
nothing is generated.
