Couldn't Map JSON Payload having Attribute Name with Space and Reserve words to C# Class in RestSharp Ver. 108

6 years back I wrote this for RestSharp version older than 108.

But now with RestSharp Version 108 I am unable to use the same as I am getting an error as

Could not load type 'RestSharp.Deserializers.DeserializeAsAttribute' from assembly 'RestSharp, Version=108.0.1.0, Culture=neutral, PublicKeyToken=598062e77f915f75'.

My JSON Payload is as:

{
    "agentType": "Sub Broker",
    "agentCode": "FWM",
    "agentName": "FWM",
    "default": "Y"
}

In my c# Class I have this; Note that default is a reserved word, hence I made it as "IsDefault" mapped to the correct attribute name using DeserializeAsAttribute from RestSharp Version prior to 108:

public class AgentInformation
    {
        public string agentType { get; set; }
        public string agentCode { get; set; }
        public string agentName { get; set; }
        [DeserializeAs(Name = "default")]
        public string isDefault { get; set; }
    }

I am calling the API from RestSharp Version 108 as:

try
            {
                var client = new RestClient("https://xxxx.io/v3/xxxxxxx");
                var request = new RestRequest();
                request.OnBeforeDeserialization = resp => { resp.ContentType = "application/json"; }; 
                var response = client.Get<AgentInformation>(request);
                var data = response;
                Console.ReadLine();
            }
            catch (Exception er)
            {

                throw er;
            }

Update:

As @jhambright suggested in his comment, I used System.Text.Json in the following way and it worked.

Note here, System.Text.Json offers JsonPropertyName

public class AgentInformation
    {
        public string agentType { get; set; }
        public string agentCode { get; set; }
        public string agentName { get; set; }
        [JsonPropertyName("default")]
        public string isDefault { get; set; }
    }

Then in my code I did the following way:

try
            {
                var client = new RestClient("https://xxx.xxx.io/v3/xxxx-xxx-xxxx-xxx-xxxxx");
                //client.AddDefaultHeader("application/json", () => new RestSharp.Serializers.Newtonsoft.Json.NewtonsoftJsonSerializer());
                var request = new RestRequest();
                request.OnBeforeDeserialization = resp => { resp.ContentType = "application/json"; }; 
                var response = await client.GetAsync(request);
                var options = new JsonSerializerOptions(JsonSerializerDefaults.Web);
                var data = JsonSerializer.Deserialize<Model.AgentInformation>(response.Content, options);

                Console.WriteLine(data.agentInformation.isDefault);
            }
            catch (Exception er)
            {

                throw er;
            }

This resource here also helped me.

I believe RestSharp is now using System.Text.Json for default json deserialization. You should be able to use [JsonPropertyName("default")] attribute to direct the deserializer.
