Nested class deserialization
I have some system where settings is nested class:
public class SomeDependencyForGlobalSystem : ISomeDependencyForGlobalSystem
{
public float ParamA { get; private set; }
public float ParamB { get; private set; }
[Serializable]
public class Settings : ModuleSettings
{
[Range(1,200)]
public float ParamA;
public float ParamB;
}
[Inject]
public void Inject(Settings settings)
{
ParamA = settings.ParamA;
ParamB = settings.ParamB;
}
}
And project editor for settings: 
All settings data stored in scriptable object:
%YAML 1.1
%TAG !u! tag:unity3d.com,2011:

Problem: after editor restart unity can't read correctly data from scriptable object. Reason - nested setting class.
Question: how to make Unity deserialize correctly nested classes?
Ok, i'm understend, unity support only one level deserialization :|
I know this is late but the current answer simply wrong ;)
The correct one would be: Unity can only serialize fields not properties! You can't have only
public float ParamA { get; private set; }
public float ParamB { get; private set; }
but should either remove the {get, private set} or add proper serialized backing fields like e.g.
public float ParamA { get{ return _paramA;} }
public float ParamB { get{ return _paramB;} }
[SerializeField] private float _paramA;
[SerializeField] private float _paramB;
If you look at yaml, u see that data is serialized and problem in DEserialization date from $$anonymous$$oduleSettings(data in fields) :)
The issue is that simply only fields are serialized and deserialized ... not properties.
