Usage

Before Unity 2020.1, Unity doesn't support serialization of generic class, you need to create a derived class from SerializableDictionary, SerializableHashSet or SerializableKeyValuePair.

    [SerializeField]
    StringStringDictionary m_StringStringDictionary;

    [SerializeField]
    StringMyClassDictionary m_StringMyClassDictionary;

    [SerializeField]
    ColorHashSet m_ColorHashSet;

    [SerializeField]
    StringIntPair m_StringIntPair;


    [Serializable]
    public class StringStringDictionary : SerializableDictionary<string, string> {}

    [Serializable]
    public class MyClass
    {
        public int i;
        public string str;
    }

    [Serializable]
    public class StringMyClassDictionary : SerializableDictionary<string, MyClass> {}

    [Serializable]
    public class ColorHashSet : SerializableHashSet<Color> {}

    [Serializable]
    public class StringIntPair : SerializableKeyValuePair<string, int> {}

After Unity 2020.1:

    [SerializeField]
    SerializableDictionary<string, string> m_StringStringDictionary;

    [SerializeField]
    SerializableDictionary<string, MyClass> m_StringMyClassDictionary;

    [SerializeField]
    SerializableHashSet<Color> m_ColorHashSet;

    [SerializeField]
    SerializableKeyValuePair<string, int> m_StringIntPair;

    [Serializable]
    public class MyClass
    {
        public int i;
        public string str;
    }

Dictionary of lists or arrays

Unity cannot serialize a array of lists or an array of arrays.

Create a class that inherits from SerializableDictionaryStorage<List<TValue>. This storage class will only contain a List<TValue> data field.

[SerializeField]
StringColorListDictionary m_colorStringListDict;


[Serializable]
public class ColorListStorage : SerializableDictionaryStorage<List<Color>> {}

[Serializable]
public class StringColorListDictionary : SerializableDictionary<string, ColorListStorage> {}

// you would have to access the color list through the .data field of ColorListStorage
List<Color> colorList = m_colorStringListDict[key].data;
