Identity DefaultConnection database to SQL Server

I using C# Identity for login/registering users. Everything works locally but when I publish live the register/login doesn't work. I believe it is due to the connection string because it is pointing to LocalDb. I've been trying to put it in my server database, but when I do, I get ApplicationUser not part of model. I'm only using the AspNetUser table for now. Any suggestions?

Default connection string

<add name="DefaultConnection" 
     connectionString="Data Source=(LocalDb)\MSSQLLocalDB;AttachDbFilename=|DataDirectory|\aspnet-WebApplication1-20171104124939.mdf;Initial Catalog=aspnet-WebApplication1-20171104124939;Integrated Security=True" 
     providerName="System.Data.SqlClient"/>

Server connection string -- I'm using gearhost as my server provider.

<add name="connectionStringName" 
     connectionString="metadata=res://*/Model1.csdl|res://*/Model1.ssdl|res://*/Model1.msl;provider=System.Data.SqlClient;provider connection string=&quot;data source=den1.mssql1.gear.host;initial catalog=databaseName;user id=userName;password=userPassword;MultipleActiveResultSets=True;App=EntityFramework&quot;" 
     providerName="System.Data.EntityClient" />

This is the DefaultConnection database context.. if I change this to my server connection string with copied identity tables, it gives me the "500, ApplicationUser not part of model"

public class ApplicationDbContext : IdentityDbContext<ApplicationUser>
{
    public ApplicationDbContext()
        : base("DefaultConnection", throwIfV1Schema: false)
    {
    }

    public static ApplicationDbContext Create()
    {
        return new ApplicationDbContext();
    }
}

Solution

Found exacly what I was looking for in this video..

I basically needed to change the default connection string created by ASP.net to be pointed in my own database. Also, I needed to know how to create the identity tables in my database. The video shows me how to do these.
