We have two new refactorings for global usings, Extract Global Using and Inline Global Using, with Find Usages support for this feature.
For
nullable reference types, we’ve split the “should never be null”
warning into two categories: one for those who look at NRT annotation
and one for those who have a runtime check for null. We’ve also added a
setting to enable runtime enforced not null warnings only, and supported
[MemberNotNull] and [MemberNotNullWhen] annotations.
We’ve implemented generic attributes support for C#11.
