✅ Rider does not recognise WebImage Helper

I assume my modern asp.net application cannot work with those attributes like WebImage or IsPost, is that correct? So my best bet is maybe working with IFormImage?

well you have the proof - the screenshot I just sent got the model folder. in there there are two model classes named ListingProjects (I don't use this anymore) and ListingProjects_ver2 (I use)

So this is where the error message came from (please see the attached mp4) When I read InternalDbSet I can only think of that error coming from

namespace WebApplication1.Data;

public class ApplicationDbContext : IdentityDbContext<PortalUsers>
{
    public ApplicationDbContext(){}
    public ApplicationDbContext(DbContextOptions<ApplicationDbContext> options)
        : base(options)
    {
    }

    public Microsoft.EntityFrameworkCore.DbSet<PortalUsers> UsersDBTable { get; set; }
    //public Microsoft.EntityFrameworkCore.DbSet<Category> CategoriesDBTable { get; set; }
    public Microsoft.EntityFrameworkCore.DbSet<ListingProjects> ListingDBTable { get; set; }
    //public Microsoft.EntityFrameworkCore.DbSet<Location> LocationDBTable { get; set; }
    public Microsoft.EntityFrameworkCore.DbSet<ListingProjects_ver2> ListingVer2_DBTable { get; set; }
    public Microsoft.EntityFrameworkCore.DbSet<ListingDtoEditClass> ListingDtoEdit_DBTable { get; set; }
    
    
}

namespace WebApplication1.Data;

public class ApplicationDbContext : IdentityDbContext<PortalUsers>
{
    public ApplicationDbContext(){}
    public ApplicationDbContext(DbContextOptions<ApplicationDbContext> options)
        : base(options)
    {
    }

    public Microsoft.EntityFrameworkCore.DbSet<PortalUsers> UsersDBTable { get; set; }
    //public Microsoft.EntityFrameworkCore.DbSet<Category> CategoriesDBTable { get; set; }
    public Microsoft.EntityFrameworkCore.DbSet<ListingProjects> ListingDBTable { get; set; }
    //public Microsoft.EntityFrameworkCore.DbSet<Location> LocationDBTable { get; set; }
    public Microsoft.EntityFrameworkCore.DbSet<ListingProjects_ver2> ListingVer2_DBTable { get; set; }
    public Microsoft.EntityFrameworkCore.DbSet<ListingDtoEditClass> ListingDtoEdit_DBTable { get; set; }
    
    
}

` This DB class -- it does have a DB table with ListingProject type, but not sure why it could be the culprit to this error

I found it strange that the error complains about ListingProjects --- my class is named ListingProjects_ver2 and it has no reference to ListingProjects. Any clue? This is my whole code https://pastebin.com/Fj82WLN2

The edit method does not edit the pre-existing data but it creates a new data entry with NULL

With FromBody I always get the server responded with a status of 415 (Unsupported Media Type) That's why I went with FromForm to get rid of this error

Still, the edited input will not get saved and the DB gets the NULL entry just like before

The edit method does not edit the pre-existing data but it creates a new data entry with NULL

So my rider does not let me set any breakpoint in code (the point will get marked by 🚫 ), I did something like this as debug

[HttpGet]  
    public JsonResult EditListingJ(int? Id)    //For getting details of the selected User  
    {
        try
        {
            
            ListingProjectsDTO StartEditListing = _context.ListingDTO_DBTable.Find(Id);
            Console.WriteLine("GET success");
            return Json(StartEditListing);
        }
        catch (Exception e)
        {
            return null;
        }
        
    }  
    
    [HttpPost]  
   
    public JsonResult EditListingJ([FromForm]ListingProjectsDTO _completeEditNowListingProjectsDto)      
    {
        try
        {
            
            _context.ListingDTO_DBTable.Update(_completeEditNowListingProjectsDto);
            _context.SaveChanges();
            Console.WriteLine("POST success");
            return Json(_completeEditNowListingProjectsDto);
        }
        catch (Exception ex)
        {
            return Json(ex.Message);
        }
    }

This code returns both of Console.WriteLine("GET success") and Console.WriteLine("POST success");
