I'm trying to add a new user to the database using the following code:

public async void SeedUsers(){
    int count=0;
    if(count>0){
        return;
    }
    else{
        string email="jujusafadinha@outlook.com.br";
        _context.Add(new User{LoginEmail=email});  
        await _context.SaveChangesAsync();  
    }
}

But it keeps giving me the following error:

System.TypeLoadException: > Method 'Create' in type 'MySql.Data.EntityFrameworkCore.Query.Internal.MySQLSqlTranslatedExpressionVisitorFactory' in assembly 'MySql.Data.EntityFrameworkCore', version=8.0.22.0, culture=medium Properties, >PublicKeyToken=c5687fc88969c44d ' is not implemented. at MySql.Data.EntityFrameworkCore.Extensions.MySQLServiceCollectionExtensions.AddEntityFrameworkMySQL(IServ>iceCollection service) at MySql.Data.EntityFrameworkCore.Infrastruct.Internal.MySQLOptionsExtension.ApplyServices(IServiceColle>ction service) at Microsoft.EntityFrameworkCore.Internal.ServiceProviderCache.ApplyServices(IDbContextOptions > Options, ServiceCollection Services) at Microsoft.EntityFrameworkCore.Internal.ServiceProviderCache.c__DisplayClass4_0.b__2(Int64 k) In System.Collections.Concurrent.ConcurrentDictionary2.GetOrAdd(TKey key, Func2 valueFactory) at Microsoft.EntityFrameworkCore.Internal.ServiceProviderCache.GetOrAdd(IDbContextOptions options, >Boolean providerRequired) at Microsoft.EntityFrameworkCore.DbContext.get_InternalServiceProvider() at Microsoft.EntityFrameworkCore.DbContext.get_DbContextDependency() at Microsoft.EntityFrameworkCore.DbContext.EntryWithoutDetectChanges[TEntity](TEntity entity) at Microsoft.EntityFrameworkCore.DbContext.SetEntityState[TEntity](TEntity entity, EntityState >entityState) at Microsoft.EntityFrameworkCore.DbContext.Add[TEntity](TEntity entity) In D:devcontatinapiDataSeedData.cs at contatinApi.Data.SeedData.SeedUsers(): line 24 at System.Threading.Tasks.Task.<>c.b__139_1(ObjectState) at System.Threading.QueueUserWorkItemCallback.<>c.<.cctor>b__6_0(QueueUserWorkItemCallback quwi) at System.Threading.ExecutionContext.RunForThreadPoolUnsafe[TState](ExecutionContext >executionContext, Action`1 callback, TState& state) in System.Threading.QueueUserWorkItemCallback.Execute() in System.Threading.ThreadPoolWorkQueue.Dispatch() In System.Threading._ThreadPoolWaitCallback.PerformWaitCallback()

User class:

public class User
    {
        public int Id{get;set;}
        public string LoginEmail{get;set;}
        public string UserName{get;set;}
        public DateTime CreatedAt{get;set;}
        public List<Contact> Contacts {get;set;}
        public List<ContactList> ContactLists{get;set;}
    }

EF Core and MySQL packages have been updated. Also, I tried using a stored procedure and it gave the same result.

Ex is:
