Inccorect 'Null check can be simplified'

[vsfeedback]

The null check of a generic argument must be done with a 'if', but intelisense says we can simplified with the '??' operator. But the '??' operator is valid only if the Type of the generic argument has the 'class' constraint, the intellisense don't care about that.

I tried to reproduce this in 15.6.2 but only get the fix offered if I add a class constraint. Could you try updating to a new version and see if the problem persists? Thanks!

This seems like it got fixed in #24173 but merged into 15.7, not 15.6? Maybe there's something wrong with my setup.

@Neme12 I updated my VS from the 15.5.7 to 15.6.3 version and it's now fixed. Thank you !
