I'm not amazing at searching, but i didn't find anything similar to my eyes. Apologies in advance if i overlooked.
This bug is pretty simple.
When using the Quick Action "Extract block to code-behind", the resulting code-behind doesn't have explicitly defined inheritance, and appears, in the file, to be a bare class. Of course, blazor is all fancy and happily runs, for the most part, despite this. (not clear why, i did get into a couple of states where roslyn was underlining these "incorrect" methods, but a restart of VS returned functionality).
Find a screen-to-gif of the issue in action below.
For the most part i was following Dan Roth's Blazor front end youtube series (Starting here: https://www.youtube.com/watch?v=sIIfnGqEIds) , but early on took the path of extracting the "Counter" c# code to a codebehind file. I ran into the issue much later when i was following along with the scaffolding in video 9.
