This issue is similar to how the other languages work in terms of adding descriptions: https://modelina.org/playground?tsIncludeDescriptions=true

This means we have to utilize the functionality of xmldoc: https://learn.microsoft.com/en-us/dotnet/csharp/language-reference/xmldoc/?redirectedfrom=MSDN

What we are looking to generate is a description per model and property:

namespace asyncapi.models
{
    using System.Collections.Generic;
    /// <summary>
    /// The light measured payload
    /// </summary>
    public class LightMeasured
    {
        /// <summary>
        /// Id of the streetlight.
        /// </summary>
        private int? id;

        /// <summary>
        /// Light intensity measured in lumens.
        /// </summary>
        private int? lumens;

        /// <summary>
        /// Date and time when the message was sent.
        /// </summary>
        private string? sentAt;

        private Dictionary<string, dynamic>? additionalProperties;

        public int? Id
        {
            get { return id; }
            set { id = value; }
        }

        public int? Lumens
        {
            get { return lumens; }
            set { lumens = value; }
        }

        public string? SentAt
        {
            get { return sentAt; }
            set { sentAt = value; }
        }

        public Dictionary<string, dynamic>? AdditionalProperties
        {
            get { return additionalProperties; }
            set { additionalProperties = value; }
        }
    }
}

We can do this through presets, you can follow this guide to add it: https://github.com/asyncapi/modelina/blob/master/docs/contributing.md#adding-a-new-preset

You can use the following existing description preset for TS as reference: https://github.com/asyncapi/modelina/blob/master/src/generators/typescript/presets/DescriptionPreset.ts
