The type 'object?' cannot be used as type parameter 'TKey' in the generic type or method 'ConcurrentDictionary<TKey, TValue>'. Nullability of type argument 'object?' doesn't match 'notnull' constraint.

Nullability of reference types in type of parameter 'y' of 'int ForeignKeySortManager.Compare(object x, object y)' doesn't match implicitly implemented member 'int IComparer<object>.Compare(object? x, object? y)' (possibly because of nullability attributes).

Nullability of reference types in type of parameter 'x' of 'int ForeignKeySortManager.Compare(object x, object y)' doesn't match implicitly implemented member 'int IComparer<object>.Compare(object? x, object? y)' (possibly because of nullability attributes).

The type 'T' cannot be used as type parameter 'TService' in the generic type or method 'OwningComponentBase<TService>'. Nullability of type argument 'T' doesn't match 'notnull' constraint.

Nullability of type of parameter 'obj' doesn't match overridden member (possibly because of nullability attributes).

Nullability of type of parameter 'errorSuggestion' doesn't match overridden member (possibly because of nullability attributes).
