求Pomelo.EntityFrameworkCore.MyCat改写源码，使.net core EF可以连mycat

[asptoc]

我已经将官方源码源码整在DEMO中，控制台的.net core EF可以连接到mycat集群进行增删改查，同样代码，写到WEB上面就不行
下面是控制台的源码：
using Microsoft.EntityFrameworkCore;
using System;
using System.Linq;

namespace DemoMyCat
{
public class Blogs
{
public long Id { get; set; }

public string Title { get; set; }

public string Content { get; set; }

public DateTime Time { get; set; }

}
public class SampleContext : DbContext
{
public DbSet<Blogs> Blogs { get; set; }

protected override void OnConfiguring(DbContextOptionsBuilder optionsBuilder)
{
base.OnConfiguring(optionsBuilder);

optionsBuilder.UseMyCat("server=192.168.1.49;port=8066;uid=admin;pwd=k_#LoadjNe990pQ23;database=TESTSCHEMA")
.UseDataNode("192.168.1.49", "blogs", "admin", "k_#LoadjNe990pQ23")

.UseDataNode("192.168.1.50", "blogs", "admin", "k_#LoadjNe990pQ23")

.UseDataNode("192.168.1.51", "blogs", "admin", "k_#LoadjNe990pQ23");
}
}


class Program
{
static void Main(string[] args)
{
//add();
//Console.WriteLine(del(975213589398949888));
Update(976271322097258496);
Console.WriteLine("操作成功!");
//Console.WriteLine(Query(976271322579603456));
Console.Read();
}

return blog.Title.ToString();
}
}
