E.g,
<Counter IncrementBy=|
This looks to be an issue with ProjectionProvider returning null here.
@TanayParikh is going to take a look at this as all his other items are blocked right now.
No automatic "|" after = is pressed, is no longer an issue as we removed the snippet support as the experience wasn't too consistent across the board between taghelper attributes, directive attributes, parameters, etc: https://github.com/dotnet/aspnetcore/issues/22228~~
Edit: We should still get the "|" here because the snippet is being handled by the OnTypeFormattingHandler.
However, that change was made 12 days after you created this issue, which makes me suspect this may be indicative of another issue. Investigating further.
