In my scena

Answer 1

I will say implementing Singleton on this persisting data issue can be a solution for this matter in case you find previous solutions much complicated

 public class GPDataDictionary
{
    private Dictionary configDictionary = new Dictionary();

    /// 

    /// Configuration values dictionary
    /// 
    public Dictionary ConfigDictionary
    {
        get { return configDictionary; }
    }

    private static GPDataDictionary instance;
    public static GPDataDictionary Instance
    {
        get
        {
            if (instance == null)
            {
                instance = new GPDataDictionary();
            }
            return instance;
        }
    }

    // private constructor
    private GPDataDictionary() { }

}  // singleton
