For now, we're blocking ENC for extension blocks. Full support will come post RTM, for now we want to make sure that nothing crashes. Contributes to #78959.

This change isn't strictly required, but it does make sure that the baseline is always valid C#, even if it has newlines or contains quotes.

It looks like this test is also adding the name, not removing it

Is there a specific reason a parameter is being renamed at the same time as adding an attribute?

It seems a bit weird that EnC believes the parameters were reordered, but, probably not related to your change.
