Cannot convert null literal to non-nullable reference type.

Cannot convert null literal to non-nullable reference type.

'SlashDevice.Set(Packet)' hides inherited member 'Device.Set(Packet)'. Use the new keyword if hiding was intended.

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

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

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