发生System.TypeInitializationException

我最近开始学习Entity Framework，而且是新手。我写了第一个简单的程序，但是没有用。我试图在Google上找到解决方案，但没有结果。我希望在这里找到答案。

ApplicationContext.cs

using Microsoft.EntityFrameworkCore;

namespace HelloApp
{
    class ApplicationContext: DbContext     
    {
        public DbSet<User> Users { get; set; }     

        public ApplicationContext()
        {
            Database.EnsureCreated();
        }

        protected override void OnConfiguring(DbContextOptionsBuilder optionsBuilder)   
        {
            optionsBuilder.UseSqlServer("Server=(localdb)\\mssqllocaldb;Database=helloappdb;Trusted_Connection=True;");
        }
    }
}

Program.cs

using System;
using System.Linq;

namespace HelloApp
{
    class Program
    {
        static void Main(string[] args)
        {
            using (ApplicationContext db = new ApplicationContext())
            {
                User user1 = new User { Name = "Tom", Age = 33 };
                User user2 = new User { Name = "Alice", Age = 26 };

                db.Users.Add(user1);
                db.Users.Add(user2);
                db.SaveChanges();
                Console.WriteLine("Successfully saved!");

                var users = db.Users.ToList();
                Console.WriteLine("List of objects:");
                foreach (User u in users)
                {
                    Console.WriteLine($"{u.Id}.{u.Name} - {u.Age}");
                }
            }
        }

    }
}

谢谢你的帮助！！！

[更新]我意识到System.TypeInitializationException告诉我发生了什么问题：

The type initializer for 'Microsoft.Data.SqlClient.SNINativeMethodWrapper' threw an exception. ---> System.ComponentModel.Win32Exception: Failed to load C:\Users\Босс\Desktop\x86\SNI.dll 

我在Google上寻找，但只能找到一个斜率的解释：

"That makes me suspect that you build it on a 64 bit system and then just transferred the files to the other machine. You need to publish the project for an x86 target to get the right native dependency resolved. Give it a try."

我在64位CPU上有64位Windows 10，但我不明白如何以另一位速率发布项目？
