Trying to convert classroom code to my hosting site.

I'm having a tough time reasoning this out, I am relatively new to .NET MVC 4 and working in a somewhat restrictive environment on a "WinHost" server and playing within their rules.

The hosing site rules are: they assign you a server address (no problem)like 10.2400.thisServer.com, they then prefix all database names with something like "USER_5777" + (my 5 char name). They require security to be "Integrated Security=False"

I am doing online MVC learning and have no problem with the local tasks and operation of the classroom code. But, I want to adapt these tasks and example projects to a real-time environment on my web host site, "WinHost" is who I use.

All classroom code assumes Microsoft SQL Server and local IIS below is an example of the current "web.config" that works perfectly locally.

C#

"<add name="MvcAuction.Models.AuctionsDataContext" connectionString="Data Source=(LocalDb)\v11.0;Integrated Security=SSPI;AttachDBFilename=|DataDirectory|\MvcAuction.Models.AuctionsDataContext.mdf" providerName="System.Data.SqlClient" />

As you can see it is an attached mdf in the "App_Data" folder

Here is the modified version of my "web.config" on the host.

C#

<add name="MvcAuction.Models.AuctionsDataContext" connectionString="Data Source=tcp:g09.winhost.com;Initial Catalog=DB_12345_auction;User ID=DB_12345_auction_user;Password=MonkeysUncle;Integrated Security=False;" providerName="System.Data.SqlClient" />

I have created a database on the host site according to their rules as I pointed out above. But it errors out the program with {"Model compatibility cannot be checked because the database does not contain model metadata. Model compatibility can only be checked for databases created using Code First or Code First Migrations."}

Please Help

If you are not using Code First Approach, Disable the initializer

C#

public class YourDbContext: DbContext 
    {
        public YourDbContext() : base("MvcAuction.Models.AuctionsDataContext")
        {            
            //Disable initializer
            Database.SetInitializer<yourdbcontext>(null);
        }
        
    }

Hope this helps
