Dear Sir: I have MVC5 application where I placed App_Data (DB_81874_dotnetstore_Data.mdf and DB_81874_dotnetstore_log.ldf) files. I copied Data Source=tcp:s10.Winhost.com;Initial Catalog=DB_81874_dotnetstore;User ID=DB_81874_dotnetstore_user;Password=******;Integrated Security=False;" I was never able to make connection with Database. Do I have to use SSMS with your server? If so how that can be done. For a week I am unable to connect to my website.
