How to fix DbUpdateConcurrencyException when removing multiple entries?

I receive this error when trying to remove entries from the table with EFC
Microsoft.EntityFrameworkCore.DbUpdateConcurrencyException: The database operation was expected to affect 1 row(s), but actually affected 30 row(s); data may have been modified or deleted since entities were loaded. See http://go.microsoft.com/fwlink/?LinkId=527962 for information on understanding and handling optimistic concurrency exceptions.
This is my code:

I followed a tutorial on the internet on how to use EFC by the teeth and for some euclidean reason, as always, the code works for others and the same code does not work when I try it out.

modelBuilder.Entity<Agent>().HasKey(a => a.Station);
So you have an entity Agent, about which you tell Entity Framework that it has a primary key column named "station".
You have a database with at least 30 records in it, and at least 30 of those records have the same value for the station column.
So despite you telling EF that station is the primary key, it isn't. So EF generates the query:
DELETE FROM agent WHERE station=#station
And the database engine happily removes all 30 records for which the station equals the station of the first record it encounters, and reports this, then EF throws, because it expected one record to be deleted, not 30.
The solution: configure the actual primary key as key, or if there isn't any, create one.

How to retrieve and store data into a db from a public api in a AWS lambda function

Using an open API (I'm using New York Times book API) create an API Gateway endpoint that does the following:
Retrieves data from an API. Stores the data in a database.
I'm able to retrieve the data and store it in a string but I'm having difficulties extracting that data from the string and storing it into a dynamo DB. Any help is appreciated thank you.

Using Linq to sql for windows phone

I am trying to show out History for my windows 8 application which includes date, time , Floor ,Zone , Longitutde and latitude. I tried the code below but there was no output in it above.
THe image you can see on the link down below that I want to show on my application.But I can see nothing when I run my program.
I have three classes for using linq to sql to retrieve database and show information through it.The main class is History.xaml.cs
using System;
using System.Collections.Generic;
using System.Linq;
using System.Net;
using System.Windows;
using System.Windows.Controls;
using System.Windows.Navigation;
using Microsoft.Phone.Controls;
using Microsoft.Phone.Shell;
using System.IO.IsolatedStorage;
using System.Data.Linq;
using System.Data.Linq.Mapping;
using System.ComponentModel;
using System.Collections.ObjectModel;
using System.Text;
using System.Data.Linq;
namespace SmartParking
{
public partial class History : PhoneApplicationPage
{
private readonly HistoryDataContext historylog;
public History()
{
InitializeComponent();
// createDB();
}
public HistoryDataContext Log
{
get { return historylog; }
}
public void createDB()
{
using (HistoryDataContext historylog = new HistoryDataContext(HistoryDataContext.DBConnectionString))
{
if (historylog.DatabaseExists() == false)
{
historylog.CreateDatabase();
addDataDB();
}
}
}
public void addDataDB()
{
using (HistoryDataContext historylog = new HistoryDataContext(HistoryDataContext.DBConnectionString))
{
HistoryDB hdb = new HistoryDB
{
// Date = DateTime.Today,
// Time = DateTime.Now.TimeOfDay,
Zone = Checkin.Zone_st,
Floor = Checkin.Floor_st,
location_latitude = Checkin.Latitud_do,
location_longtitud = Checkin.Longtitude_do
};
historylog.history.InsertOnSubmit(hdb);
historylog.SubmitChanges();
GetHistoryLog();
}
}
public IList<HistoryDB> GetHistoryLog()
{
IList<HistoryDB> HistoryList = null;
using (HistoryDataContext historylog = new HistoryDataContext(HistoryDataContext.DBConnectionString))
{
IQueryable<HistoryDB> query = from histoy in historylog.history select histoy;
HistoryList = query.ToList();
}
return HistoryList ;
}
}
}
The next class is HistoryDB.cs with the tables and columns
[Table]
public class HistoryDB
{
[Column(CanBeNull = false)]
public DateTime Date
{ get; set; }
[Column(CanBeNull = false)]
public TimeSpan Time
{ get; set; }
[Column(CanBeNull = false)]
public String Zone

[Column(CanBeNull = false)]
public String Floor
{ get; set; }
[Column(CanBeNull = false)]
public double location_latitude
{ get; set; }
[Column(CanBeNull = false)]
public double location_longtitud
{ get; set; }
}
The next class is HistoryDataContext.cs.
public class HistoryDataContext:DataContext
{
public static string DBConnectionString = "Data Source=isostore:/History.sdf";
public HistoryDataContext(string DBConnectionString)
: base(DBConnectionString)
{
}
public Table<HistoryDB> history
{
get
{
return this.GetTable<HistoryDB>();
}
}
}
What I am trying is to get information from the NFC tag and store it in the local database and then retrieve it in the history page. The code below is to read from nfc tag but I dunno how again to save in the local databse from there and retrive it back in the history page.

SetLogStatus("Floor: " + Floor_st + " Zone: " + Zone_st );
SetFloorStatus("Longitude: " + latitude + " Longitude: " + longtitude);
store.addDataDB();
}
}
}
}
}
The Image of the table is in the link below
https://www.dropbox.com/s/g87yta6hegjstge/Untitled.png?dl=0

try this:
In Database There Should be a Primary key otherwise it would Throw an Exception and the Datatype that is TimeSpan not supported so you need to take DateTime or String as Done Below :
[Table]
public class HistoryDB
{
[Column(IsPrimaryKey = true)]
public int Id { get; set; }
[Column(CanBeNull = false)]
public DateTime Date
{ get; set; }
[Column(CanBeNull = false)]
public DateTime Time
{ get; set; }
[Column(CanBeNull = false)]
public String Zone
{ get; set; }
[Column(CanBeNull = false)]
public String Floor
{ get; set; }
[Column(CanBeNull = false)]
public double location_latitude
{ get; set; }
[Column(CanBeNull = false)]
public double location_longtitud
{ get; set; }
}
public void addDataDB()
{
using (HistoryDataContext historylog = new HistoryDataContext(HistoryDataContext.DBConnectionString))
{
HistoryDB hdb = new HistoryDB
{
Id = 0,
Date = DateTime.Today,
Time = DateTime.Now,
Zone = "Zone",
Floor = "Floore",
location_latitude = 00.00,
location_longtitud = 00.00
};
historylog.history.InsertOnSubmit(hdb);
historylog.SubmitChanges();
GetHistoryLog();
}
}
I have implemented above thing and its working Properly
