Json data parsing in MAUI .NET 8

Initially, in Xamarin Forms, we were using response.ToObject() for JSON parsing. Here is the code snippet for your reference
(response.ResponseData).ToObject<DataDTO>()
But in .NET 8 it was giving error
Microsoft.CSharp.RuntimeBinder.RuntimeBinderException: ''System.Text.Json.JsonElement' does not contain a definition for 'ToObject''
Hence we tried the following generic method to avoid code repetition in .NET MAUI.
using System.Text.Json;
public static T DeserializeTheObject<T>(dynamic responseData)
{
return JsonSerializer.Deserialize<T>(responseData, new JsonSerializerOptions
{
PropertyNameCaseInsensitive = true, // Ensure case-insensitive deserialization
PropertyNamingPolicy = null,
Converters = {
new JsonStringEnumConverter()
}
});
}
using System.Text.Json;
public static List<T> DeserializeJsonArrayList<T>(dynamic responseData)
{
return JsonSerializer.Deserialize<List<T>>(responseData, new JsonSerializerOptions
{
PropertyNameCaseInsensitive = true, // Ensure case-insensitive deserialization
PropertyNamingPolicy = null,
Converters = {
new JsonStringEnumConverter()
}
});
}
This code works fine in Android in debug mode but the app crashes in release mode giving the below error
