How De-serialize response JSON with dynamic keys?

I know that this question is asked many times but still I'm struggling to understand this. I have below json to c# converted class.
// Root myDeserializedClass = JsonConvert.DeserializeObject<Root>(myJsonResponse);

In this above JSON, classes mentioned below are dynamic keys into response JSON.
Haythandi
Beautifulnari
The problem is that values Haythandi and beautifulNari as class name (if convert to c#) which are actually ids of that particular record. How do I convert these id's into c# class?, I have tried multiple approaches like using Dictionaries, JObjects, dynamic and Expando classes but not result. Any help would be much appreciated.

I think you need change one of the 'character classes' to:
public class MyClassWithPosts // was Beautifulnari
{
public List<Post> posts { get; set; }
public long totalViewsCount { get; set; }
}
After that data can become a dictionary (update: a list of dictionaries):
public class Root
{
public int code { get; set; }
public List<Dictionary<string, MyClassWithPosts>> data { get; set; }

Entity Framework cannot insert data

I am making this a school project and I am first time using the Entity Framework so don't be too harsh about it. These are my tables/classes.
public class Database : DbContext
{
public Database() {}
public DbSet<Producer> Producers { get; set; }
public DbSet<Song> Songs { get; set; }
public DbSet<ProducerSong> ProducerGlasbos { get; set; }
}
public class Song
{
public int Id { get; set; }
public string Title { get; set; }
public int Length { get; set; }
public int Views { get; set; }
}
public class Producer
{
[DatabaseGenerated(DatabaseGeneratedOption.None)]
public int Id { get; set; }
public string name { get; set; }
public string surname { get; set; }
public int birth { get; set; }
}
public class ProducerSong
{
[DatabaseGenerated(DatabaseGeneratedOption.None)]
public int Id { get; set; }
public Producer Producer { get; set; }
public Song Songs { get; set; }
public int year { get; set; }
}
When I try to inset new instance of a class into table/database in just crashes and throws error
Data.Glasbas.Add(new Glasba { length = 200, Naslov = "Bolecina", views= 313});
Error screenshot: Look at me
Thanks for helping.

public class Database : DbContext
{
public Database() { }
public DbSet<Producer> Producers { get; set; }
public DbSet<Song> Songs { get; set; }
public DbSet<ProducerSong> ProducerGlasbos { get; set; }
public class ProducerSong
{
[System.ComponentModel.DataAnnotations.Key]
public int ProducerSongID { get; set; }
public Producer Producer { get; set; }
public Song Songs { get; set; }
public int year { get; set; }
}
public class Song
{
[System.ComponentModel.DataAnnotations.Key]
public int Id { get; set; }
public string Title { get; set; }
public int lenght { get; set; }
public int views { get; set; }
//ForeignKey
public int ProducerSongID { get; set; }
public ProducerSong ProducerSong { get; set; }
}
public class Producer
{
[System.ComponentModel.DataAnnotations.Key]
public int Id { get; set; }
public string name { get; set; }
public string surname { get; set; }
public int birth { get; set; }
//ForeignKey
public int ProducerSongID { get; set; }
public ProducerSong ProducerSong { get; set; }
}
}

The problem was in constructors if I used constructors to create objects it just don't work odd but what can you do..

Can a primary key called twice in another table as foreign key using Entity Framework?

How can I use a primary key as a foreign key of another table's in two columns.
public class ResumeSharing
{
[Key]
public int ResumeSharingId { get; set; }
[ForeignKey("AppliedJobs")]
public int AppliedJobId { get; set; }
public virtual AppliedJob AppliedJobs { get; set; }
public bool OwnCompany { get; set; }
[Display(Name = "RecruiterFrom")]
public int RecruiterId { get; set; }
public virtual Recruiter Recruiters { get; set; }
[Display(Name = "RecruiterTo")]
public int RecruiterId { get; set; }
public virtual Recruiter Recruiters { get; set; }
[ForeignKey("Companies")]
public int CompanyId { get; set; }
public virtual Company Companies { get; set; }
public string SharedFiles { get; set; }
}
I want to call RecruiterId twice in this table. How can I do this?

you have to add navigation properties
public class ResumeSharing
{
[Key]
public int ResumeSharingId { get; set; }
[ForeignKey("AppliedJob")]
public int AppliedJobId { get; set; }
public virtual AppliedJob AppliedJob { get; set; }
public bool OwnCompany { get; set; }
[Display(Name = "RecruiterFrom")]
public int RecruiterFromId { get; set; }
[ForeignKey(nameof(RecruiterFromId))]
[InverseProperty("RecruiterFroms")]
public virtual Recruiter RecruiterFrom { get; set; }
[Display(Name = "RecruiterTo")]
public int RecruiterToId { get; set; }
[ForeignKey(nameof(RecruiterToId))]
[InverseProperty("RecruiterTos")]
public virtual Recruiter RecruiterTo { get; set; }
[ForeignKey("Company")]
public int CompanyId { get; set; }
public virtual Company Company { get; set; }
public string SharedFiles { get; set; }
}
public class Recruiter
{
[Key]
public int Id { get; set; }
[InverseProperty(nameof(ResumeSharing.RecruiterFrom))]
public virtual ICollection<Recruiter> RecruiterFroms { get; set; }
[InverseProperty(nameof(ResumeSharing.RecruiterTo))]
public virtual ICollection<Recruiter> RecruiterTos { get; set; }
}

Issue With EF Core ThenInclude Against A Collection

I'm running into this compile error when using ThenInclude on a entity. The error is listed below. I can't see anything wrong with the relationships between the two entities. What gives, I'm banging my head against a wall here!
'ICollection<OptionType>' does not contain a definition for 'ProductOption'
and no extension method 'ProductOption' accepting a first argument of type
'ICollection<OptionType>' could be found (are you missing a using directive or
an assembly reference?)
Here are the two entities in question and related code

Trouble using all members in a class. Why can I only use the list?

I have the following class object structure:

public DataObj3 data { get; set; }
}
public class DataObj3
{
public string survey_id { get; set; }

public string nickname { get; set; }
public TitleObj title { get; set; }
public List<PagesObj> pages { get; set; }
}
public class Custom_VariablesObj
{
public string variable_label { get; set; }

}

public List<QuestionObj> questions { get; set; }
}

public string heading { get; set; }
public string position { get; set; }

public List<AnswerObj> answers { get; set; }
}
public class QuestionTypeObj
{
public string family { get; set; }

}

}
public class ItemsObj
{
public string answer_id { get; set; }
public int position { get; set; }
public string type { get; set; }
public string text { get; set; }
}
I 've deserialized json into this object via:
var results_SurveyDetails = deserializer.Deserialize<StatusObj3>(json_returned);
I'm trying to loop thru the pages by:
foreach (var page in results_SurveyDetails.data.pages)
However, not all members of page are available to use.
Only the page.questions is there and not page_id, heading and subheading.
What am I doing wrong?

You are missing public on your other properties in class PagesObj.
