Question

I have a problem with MySql and Entity Framework Code First.

My Connection String at the web.config.xml

<add name="EntityContext" connectionString="Server=127.0.0.1; port=8080 Database=simple_crud; Uid=root; Pwd=;" providerName="MySql.Data.MySqlClient" />

My Context:

public class EntityContext : DbContext
{
    public DbSet<Pessoa> Pessoas { get; set; }
}

My Class:

[Table("pessoa")]
public class Pessoa
{
    [Key]
    [Column("Id")]
    public int Id { get; set; }

    [Column("Nome")]
    public string Nome { get; set; }
}

My Controller

public EntityContext db = new EntityContext();

public ActionResult Index()
{
     List<Pessoa> pessoas = db.Pessoas.ToList(); // here is the error
     return View(pessoas);
}

So, when I press F5 I got this: “Input string was not in a correct format”.

What I’m miss?

UPDATE

Stack Trace:

Gathering all comments into answer.

Add semicolon after port=3306; and check your mysql listening port (maybe 3306, mysql default?). Resulting connection string:

<add name="EntityContext" connectionString="Server=127.0.0.1; port=3306; Database=simple_crud; Uid=root; Pwd=;" providerName="MySql.Data.MySqlClient" />
