Cannot convert null literal to non-nullable reference type.

Possible null reference return.

Use 'SymbolEqualityComparer' when comparing symbols

The field 'Class1._test' is never used

The field 'Class1._guidTest' is never used

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

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

Nullability of reference types in return type of 'IEntity? Entity.Parent.get' doesn't match implicitly implemented member 'IEntity IEntity.Parent.get' (possibly because of nullability attributes).
