Doubt with Entityframework (Migration)

Question

I’m trying to make my code run, but I’m not getting it because of this Error

Severity Code Description Project File Line Error CS0311 The type 'Controleinterno.Migrations.Controleinterno.Controleintcontexto' cannot be used as type Parameter 'Tcontext' in the Generic type or method 'Dbmigrationsconfiguration'. There is no implicit Reference Conversion from 'Controleinterno.Migrations.Controleinterno.Controleintcontexto' to 'System.Data.Entity.Dbcontext'. Controleinterno F: Documents Visual Studio 2015 Projects Internal Control Controleinterno Migrations Configuration.Cs 6

using ControleInterno.Model;
using System.Data.Entity;

namespace ControleInterno
{
    class ControleIntContexto : DbContext
    {
        public ControleIntContexto()
        {
            Configuration.LazyLoadingEnabled = false;
        }

        public DbSet<Produto> Produtos { get; set; }
    }
}

Follow the code from the Configuration.Cs file

namespace ControleInterno.Migrations
{
    using System;
    using System.Data.Entity;
    using System.Data.Entity.Migrations;
    using System.Linq;

    internal sealed class Configuration : DbMigrationsConfiguration<ControleInterno.ControleIntContexto>
    {
        public Configuration()
        {
            AutomaticMigrationsEnabled = false;
        }

        protected override void Seed(ControleInterno.ControleIntContexto context)
        {
            //  This method will be called after migrating to the latest version.

            //  You can use the DbSet<T>.AddOrUpdate() helper extension method 
            //  to avoid creating duplicate seed data. E.g.
            //
            //    context.People.AddOrUpdate(
            //      p => p.FullName,
            //      new Person { FullName = "Andrew Peters" },
            //      new Person { FullName = "Brice Lambson" },
            //      new Person { FullName = "Rowan Miller" }
            //    );
            //
        }
    }
}

This here was generating ambiguity of names:

namespace ControleInterno
{
    class ControleIntContexto : DbContext
    { ... }
}

How did you remove the context of namespace right from him (ControleInterno.Models), note that the compiler solved the context name as follows:

ControleInterno.Migrations.ControleInterno.ControleIntContexto

And that’s obviously wrong.

Just change the namespace of the context and correct the references that returns to function.
