You can try in this way.

// Construct programmatically
renderer.HostConfig = new AdaptiveHostConfig() 
{
  FontFamily = "Comic Sans",
  FontSizes = {
    Small = 15,
    Default = 20,
    Medium = 25,
    Large = 30,
    ExtraLarge= 40
  }
};

// Or parse from JSON
renderer.HostConfig  = AdaptiveHostConfig.FromJson(@"{
""fontFamily"": ""Comic Sans"",
""fontSizes"": {
    ""small"": 25,
    ""default"": 26,
    ""medium"": 27,
    ""large"": 28,
    ""extraLarge"": 29
  }
}");
