Answer 1

I got this solution using below code, I can hardcode connection string using C# code without using config file.

 public class SingleConnection
    {
        private SingleConnection() { }
        private static SingleConnection _ConsString = null;
        private String _String = null;

        public static string ConString
        {
            get
            {
                if (_ConsString == null)
                {
                    _ConsString = new SingleConnection { _String = SingleConnection.Connect() };
                    return _ConsString._String;
                }
                else
                    return _ConsString._String;
            }
        }

        public static string Connect()
        {
            //Build an SQL connection string
            SqlConnectionStringBuilder sqlString = new SqlConnectionStringBuilder()
            {
                DataSource = "SIPL35\\SQL2016".ToString(), // Server name
                InitialCatalog = "Join8ShopDB",  //Database
                UserID = "Sa",         //Username
                Password = "Sa123!@#",  //Password
            };
            //Build an Entity Framework connection string
            EntityConnectionStringBuilder entityString = new EntityConnectionStringBuilder()
            {
                Provider = "System.Data.SqlClient",
                Metadata = "res://*/ShopModel.csdl|res://*/ShopModel.ssdl|res://*/ShopModel.msl",
                ProviderConnectionString = @"data source=SIPL35\SQL2016;initial catalog=Join8ShopDB2;user id=Sa;password=Sa123!@#;"// sqlString.ToString()
            };
            return entityString.ConnectionString;
        }

and using DbContext using like this:

Join8ShopDBEntities dbContext = new Join8ShopDBEntities(SingleConnection.ConString);
