Error accessing data in Mysql with EF6

Question

When I try to access data in Mysql via lambda(EF), Visual Studio returns the following error:

Falha no método >'MySql.Data.Entity.EFMySqlCommand.set_DbConnection(System.Data.Common.DbConnection)' ao tentar acessar o método 'MySql.Data.MySqlClient.MySqlConnection.get_Settings()'.

I tried searching the internet but I couldn’t find anything that could help me with this error. Follow the Main Controller Code

    using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Data.Entity;
using MySql.Data.Entity;

using View.Model;
using System.Security.Cryptography;

namespace View
{
public class MainController
{
    remoteEntities remote = new remoteEntities();

    public bool validaLogin(string usuario, string senha)
    {
        string novaSenha = getMD5Hash(senha);
        var resultado = remote.Motorista.Select(x => new { x.ID, x.Login, x.Senha, x.Nome }).Where(u => u.Login == usuario && u.Senha == novaSenha).ToList();
        if (resultado.Count > 0)
            return true;
        else
            return false;
    }

    public static string getMD5Hash(string input)
    {
        var md5Hash = MD5.Create();
        // Converter a String para array de bytes, que é como a biblioteca trabalha.
        var data = md5Hash.ComputeHash(Encoding.UTF8.GetBytes(input));

        // Cria-se um StringBuilder para recompôr a string.
        var sBuilder = new StringBuilder();

        // Loop para formatar cada byte como uma String em hexadecimal
        for (int i = 0; i < data.Length; i++)
        {
            sBuilder.Append(data[i].ToString("x2"));
        }

        return sBuilder.ToString();
    }

        if (hasConnection)
            hasConnection = webClient("http://zerohoravirtual.com/");

        return hasConnection;

Connection created with ADO.Net, connector version . net 8.0.10-rc and plugin version of visual studio 2.0.5 M4

I solved the problem by following the steps of another question I had posted here on Sopt. Link: Mysql net Connector and Entity Framework problem

When creating the entity model, App.config creates the following dependency:

<dependentAssembly>
    <assemblyIdentity name="MySql.Data" publicKeyToken="c5687fc88969c44d" culture="neutral" />
    <bindingRedirect oldVersion="0.0.0.0-8.0.10.0" newVersion="8.0.10.0" />
  </dependentAssembly>

Change the dependency to:

<dependentAssembly>
    <assemblyIdentity name="MySql.Data" publicKeyToken="c5687fc88969c44d" culture="neutral" />
    <bindingRedirect oldVersion="0.0.0.0-6.9.11.0" newVersion="6.9.11.0" />
  </dependentAssembly>

Because when installed Mysql for Visual Studio in version 2.0.5 M4, it creates the dependency with the RC version of Mysql Connector/Net and as it is not really installed the RC version is returned this error. Changing the dependency error disappears.
