Question

I’m trying to add the password to my string connection in the constructor of my DBContext like this

public partial class Control : DbContext
{
    public Control(string conexion): base(crearConexion(conexion))
    {

    }

    public static String crearConexion(string nombreConexion) 
    {
        string conexion = ConfigurationManager.ConnectionStrings[nombreConexion].ConnectionString;
        SqlConnectionStringBuilder sqlBuilder = new SqlConnectionStringBuilder(conexion);
        sqlBuilder.Password = "somepassword";
        return sqlBuilder.ToString();
    }
}

But It throws this exception
system.argumentexception keyword not supported 'metadata'

Why am I doing wrong??

Try using the EntityConnectionStringBuilder.

If you look at an EF connection string (check your app.config file), you’ll see the sql server connection string is part of it, but also that there is additional information, which the SqlConnectionStringBuilder can’t parse:

metadata=res://*/Model1.csdl|res://*/Model1.ssdl|res://*/Model1.msl;provider=System.Data.SqlClient;provider connection string="data source=localhost;initial catalog=Test;integrated security=True;multipleactiveresultsets=True;App=EntityFramework"
