I have a project with Asp.Net core 3.1. I created a View component to display some data into my view but I got an error: Type 'CMS.Models.SalonPromo' in Assembly 'CMS.Plugin.Product, Version=1.0.0.1, Culture=neutral, PublicKeyToken=null' is not marked as serializable.
This is the detail of that error:
System.Runtime.Serialization.SerializationException: Type 'CMS.Domains.Models.SalonPromo' in Assembly 'CMS.Plugin.Product, Version=1.0.0.1, Culture=neutral, PublicKeyToken=null' is not marked as serializable.

And this is my model:
public class SalonPromo
{
public int SalonId { get; set; }
public int PositionId { get; set; }
public int[] ProductIds { get; set; }
public string Banner { get; set; }
public string Description { get; set; }
}
And this is my ViewComponent code behind:
public async Task<IViewComponentResult> InvokeAsync(int position)
{
try
{
var salonPromo = await _cacheAppService.ExecuteAsync(() => _salonService.GetSalonPromoByPosition(position), StaticVariable.CacheDataExpireShortTime);
return View(salonPromo);
}
catch (Exception ex)
{
_logger.LogError(ex, ex.Message);
return View(new SalonPromo());
}
}
Thanks for any suggestions.

You have to add a
[Serializable]filter attribute to yourSalonPromomodel which you want to serialize.[Serializable] public class SalonPromo { public int SalonId { get; set; } public int PositionId { get; set; } public int[] ProductIds { get; set; } public string Banner { get; set; } public string Description { get; set; } }I hope it helpful for you.
