.NET C# retrieving data from Firebase

I'm facing some problems while retrieving data to my .net app from database hosted on Firebase. While debugging I noticed that response contains [{"Description":"desccc","Id":2},{"Description":"asdfasdf","Id":1}] and this is the only record in my db so I think for this moment everything is ok. Unfortunatelly, when trying to put this data into result it throws error like this:

{System.MissingMethodException: No parameterless constructor defined for this object. at System.Activator.CreateInstanceT at RestSharp.Deserializers.JsonDeserializer.Deserialize[T](IRestResponse response) at Rate_Your_Game.Controllers.GameController.GetGames() in PATH/Rate Your Game\Controllers\GameController.cs:line 49}

[HttpGet("[action]")]
public async Task<Game[]> GetGames()
{
    try
    {
        client = new FireSharp.FirebaseClient(config);
        FirebaseResponse response = await client.GetTaskAsync("Games/");
        Game[] result = response.ResultAs<Game[]>();
        return result;
    }
    catch (Exception e)
    {
        throw e;
    }
}

This is my Game class

public class Game
    {
        public Game() {}

        public int Id { get; set; }
        public string Description{ get; set; }    
        
    }

The Game class needs to have parameterless constructor.

public class Game {
     public Game(){
     }

     ....
}
