localhost connection (ASP.NET MVC)

Question

I've been trying to put a stored procedure in the website that I'm working on right now, I'm using ASP.NET MVC. So I decided to create a class named: RegisterRepository.cs, under the Repository folder but whenever I tried to send a registration form I always get this localhost refused to connect error. I've already check the connection strings but I can't see the problem. I hope someone can help me. Thank you.

This is my RegisterRepository class:

public class RegisterRepository
{
    private SqlConnection con;
    //To Handle connection related activities
    private void connection()
    {
        string constr = ConfigurationManager.ConnectionStrings["DefaultConnection"].ToString();
        con = new SqlConnection(constr);

    }


    public bool Register(TalentInfo model)
    {
        connection();

        try
        {
            SqlCommand com = new SqlCommand("SP_INSERT_TALENT_INFO", con);
            com.CommandType = CommandType.StoredProcedure;
            com.Parameters.AddWithValue("@Talent_Name", model.Talent_Name);
            com.Parameters.AddWithValue("@Talent_Email", model.Talent_Email);
            com.Parameters.AddWithValue("@Talent_SelfPromotion", model.Talent_SelfPromotion);
            con.Open();
            int i = com.ExecuteNonQuery();
            con.Close();
            if (i >= 1)
            {
                return true;
            }
            else
            {

                return false;
            }


        }

        catch
        {
            return Register(model);
        }
        finally
        {
            con.Close();
        }

    }


}

And this is my Web.config:

@Larry I just add my controller Sir. :) Yes, It's loading. But when I'm trying to send the registration form I always get this: localhost refused to connect. — Kendall H.

Which DB has your stored proc, DefaultConnection or TalentInfoEntities? Your connection is pointing to the former. Try ConnectionStrings["TalentInfoEntities"] — Steve Greene
– Steve Greene, Commented Jun 29, 2016 at 2:35
@SteveGreene It's in the TalentInfoEntities. I tried the ConnectionStrings["TalentInfoEntities"] Sir, then I got this error: System.ArgumentException: Keyword not supported: 'metadata' '{ string constr = ConfigurationManager.ConnectionStrings["TalentInfoEntities"].ToString(); con = new SqlConnection(constr) }' — Kendall H.

Yes, you don't need the metadata for a SQL connection. Remove the garbage from that connection string: metadata=res://*/Models.TalentInfo.csdl|res://*/Models.TalentInfo.ssdl|res://*/Models.TalentInfo.msl; — Steve Greene

Try changing your connection string to something like this:

<add name="TalentInfoEntities" connectionString="Data Source=GAYLE-PC\SQLEXPRESS;Initial Catalog=Yes.org;Integrated Security=SSPI; MultipleActiveResultSets=true" providerName="System.Data.SqlClient" />
