Entity Framework attempting to add records to wrong table [closed]

I have never had an issue with Entity Framework attempting to save to the wrong table before. However, today I've run into this issue.
I am attempting to save to a table called dbo.Accounts in SQL Server and for some strange reason, the SQL that it creates is the following.
DECLARE #inserted0 TABLE ([Id] int, [_Position] [int]);
MERGE [Accounts] USING (
VALUES (#p0, #p1, #p2, #p3, 0),
(#p4, #p5, #p6, #p7, 1),
(#p8, #p9, #p10, #p11, 2)) AS i ([CreateDate], [LastUpdated], [Name], [ParentId], _Position) ON 1=0
WHEN NOT MATCHED THEN
INSERT ([CreateDate], [LastUpdated], [Name], [ParentId])
VALUES (i.[CreateDate], i.[LastUpdated], i.[Name], i.[ParentId])
OUTPUT INSERTED.[Id], i._Position
INTO #inserted0;
SELECT [i].[Id] FROM #inserted0 i
ORDER BY [i].[_Position];
INSERT INTO [AspNetUserRoles] ([RoleId], [UserId])
VALUES (#p12, #p13);
',N'#p0 datetime2(7),#p1 datetime2(7),#p2 nvarchar(100),#p3 int,#p4 datetime2(7),#p5 datetime2(7),#p6 nvarchar(100),#p7 int,#p8 datetime2(7),#p9 datetime2(7),#p10 nvarchar(100),#p11 int,#p12 nvarchar(450),#p13 nvarchar(450)',#p0='2022-01-27 11:19:59.5774258',#p1='2022-01-27 11:19:59.5774300',#p2=N'Test Account',#p3=1,#p4='2022-01-27 11:24:37.7412127',#p5='2022-01-27 11:24:37.7412136',#p6=N'test',#p7=1,#p8='2022-01-27 11:28:45.9794153',#p9='2022-01-27 11:28:45.9794169',#p10=N'test',#p11=1,#p12=N'5d0f3665-110a-4986-9bbf-3f2b7da0ccbf',#p13=N'db9f3ebb-3e0d-4972-a8f9-c7cdb10ed94f'
As you can see it's attempting to save the account, AND trying to create a UserRole.
The exception is the following:

And the code that I am calling:

{

entity.LastUpdated = DateTime.Now;
if (entity.ParentId == 0)
entity.ParentId = 1;
Context.Accounts.Add(entity);
var a = await Context.SaveChangesAsync(token);
return entity;
}
// ApplicationDbContext
public virtual DbSet<Account>? Accounts { get; set; }
protected override void OnModelCreating(ModelBuilder modelBuilder)
{
base.OnModelCreating(modelBuilder);
modelBuilder.Entity<Account>()
.HasMany(x => x.ChildAccounts)
.WithOne(x => x.Parent);
modelBuilder.Entity<Account>()
.Property(x => x.ParentId)
.IsRequired(false);
//... other configuration
}
// model
[Table("Accounts", Schema = "dbo")]
public class Account:BaseEntity
{
[StringLength(100), Required]
public string Name { get; set; }
public int? ParentId { get; set; }
public Account? Parent { get; set; }
public ICollection<Account>? ChildAccounts { get; set; }
}
Why would this happen with only accounts, all of the other entities work correctly? Is there something in the name Account that is causing this issue?
**Update**
In the `ChangeTracker.DebugView` I see this:

}
var response = await Repository.CreateAsync(model, token);
return Ok(response);
}
catch (Exception e)
{
Logger.LogError(e, e.Message);

EF.Core Multithreading The timeout period elapsed

I am running a BackgroundTask in my ASP.NET Core 5 app which creates some entities inside my database. My idea was to run it in multiple tasks to speed up the generator.
public class GeneratorService : BackgroundService
{
private const int TaskCount = 8;
private uint _index;
private readonly List<Task> _tasks;
private readonly IServiceScopeFactory _serviceScopeFactory;
public GeneratorService(IServiceScopeFactory serviceScopeFactory)
{
_serviceScopeFactory = serviceScopeFactory;
_tasks = new List<Task>();
}
protected override async Task ExecuteAsync(CancellationToken stoppingToken)
{
while (stoppingToken.IsCancellationRequested == false)
{
for (uint i = 0; i < TaskCount; i++)
{
var i1 = i;
var task = new Task(async () => await Generate(_index + i1, stoppingToken));
task.Start();
_tasks.Add(task);
}
Task.WaitAll(_tasks.ToArray(), stoppingToken);
_tasks.Clear();
_index += TaskCount;
await Task.Delay(10, stoppingToken);
}
}
private async Task Generate(uint index, CancellationToken stoppingToken)
{
using var scope = _serviceScopeFactory.CreateScope();
var context = scope.ServiceProvider.GetService<DataContext>();
var repository = scope.ServiceProvider.GetService<Repository>();
var generator = scope.ServiceProvider.GetService<Generator>();
// A simple return await FirstOrDefaultAsync(e => e.Number == index)
var entity = await repository.GetByNumberAsync(index);
if (entity== null) ...
generator.GenerateChildren(entity);
await context.SaveChangesAsync(stoppingToken);
Console.WriteLine($"Entity {index} generated");
}
}
The generator loop runs for about 100 - 200 entities, but then it starts throwing me exceptions:

I am registering the DataContext in an extension method:
public static IServiceCollection ConfigureDatabase(this IServiceCollection services,
IConfiguration configuration)
{
var connectionString = // I get my connection string via a json file
services.AddDbContext<DataContext>(options =>
{
options.UseSqlServer(connectionString);
options.EnableSensitiveDataLogging();
});
return services;
}
This is a SQL Server Database running on my localhost.
If I am right, the DataContext is registered as a Scoped Service. So if I am creating a scope inside the BackgroundTask, it will automatically dispose the DataContext after the Task completed.
Or is this a SQL Server related issue where it could not handle that many requests simultaneously?

Bot Framework Skill - Invalid status code Unauthorized - reference to local path in stack trace

Since I see references to the skill's location on my disk I assume I'm doing the using the botskill connect tool incorrectly. This is how I'm invoked it. botskills connect --botName SomeBotName --remoteManifest "http://MyCalendarSkill.azurewebsites.net/api/skill/manifest" --luisFolder "C:\Users\MyName\Desktop\GitHub\botframework-solutions\skills\src\csharp\calendarskill\calendarskill\Deployment\Resources\LU\en\" --cs
Should I point the luisFolder parameter at the same path in Azure? Am I doing something else wrong?

.net core 2.2 DB connection errors full stack trace

I have an application running in .net core 2.2 with DBContextPool.
I'm doing load testing on the application and it seems to crash under high load; it seems an SQL query (I'm connecting to MySQL database) is timing out. The error I get is here:

As you can see, the stack trace stops while still inside the EF Core library.
Is there any way to display the full stack trace? All the way up to my service/controller level code?
I can then determine the cause of this much more easily.

Thanks for any help.

The error is quite clear at the top of the stack trace you posted, although these big error messages can be hard to read sometimes:
fail: Microsoft.EntityFrameworkCore.Database.Command[20102]
Failed executing DbCommand (133ms) [Parameters=[#__normalizedEmail_0='?' (Size = 256)], CommandType='Text', CommandTimeout='30']
SELECT TOP(1) [u].[Id], [u].[AccessFailedCount], [u].[ConcurrencyStamp], [u].[Email], [u].[EmailConfirmed], [u].[FirstName], [u].[LastName], [u].[LockoutEnabled], [u].[LockoutEnd], [u].[NormalizedEmail], [u].[NormalizedUserName], [u].[PasswordHash], [u].[PhoneNumber], [u].[PhoneNumberConfirmed], [u].[SecurityStamp], [u].[TwoFactorEnabled], [u].[UserName]
FROM [AspNetUsers] AS [u]
WHERE [u].[NormalizedEmail] = #__normalizedEmail_0
System.Data.SqlClient.SqlException (0x80131904): Invalid object name 'AspNetUsers'.
So the system is trying to run the query:
SELECT TOP(1) [u].[Id], [u].[AccessFailedCount], [u].[ConcurrencyStamp], [u].[Email], [u].[EmailConfirmed], [u].[FirstName], [u].[LastName], [u].[LockoutEnabled], [u].[LockoutEnd], [u].[NormalizedEmail], [u].[NormalizedUserName], [u].[PasswordHash], [u].[PhoneNumber], [u].[PhoneNumberConfirmed], [u].[SecurityStamp], [u].[TwoFactorEnabled], [u].[UserName]
FROM [AspNetUsers] AS [u]
WHERE [u].[NormalizedEmail] = #__normalizedEmail_0
And is getting the error:
System.Data.SqlClient.SqlException (0x80131904): Invalid object name 'AspNetUsers'.
You should check that the table exists and that the user account you are using has access to the table. You could even try running the query yourself from SQL Management Studio to see what happens
