Where is my MVC 5 code-first database created? (not using AttachDbFilename) - asp.net-mvc

Question

I have the following connection string in my MVC 5 weApp:
<connectionStrings>
<add name="DefaultConnection" connectionString="Data Source=.\SQLEXPRESS;User Instance=True;Initial Catalog=MatWebDB;Integrated Security=True" providerName="System.Data.SqlClient" />
I'm using Entity Framework code-first and Identity 2 for forms authentication.
Evreything seems to work fine: i register a new user and it logs in properly.
The problem is that i cannot find the database that was created; in my SQL Server Management Studio there is no "MatWebDB" database created.
What i want to do is to use the same database generated automatically by the Identity 2 authentication, for my own POCO entity objects. And know where is it created.
Thanks!

Answer 1

The easiest way to combine them is to have your application context inherit from the identity context and set the connection string there:
public class ApplicationDbContext : IdentityDbContext<ApplicationUser>
{
static ApplicationDbContext()
{
// Set the database intializer which is run once during application start
// Use an initializer that will create the database, or create it in SSMS first
Database.SetInitializer(new CreateDatabaseIfNotExists<ApplicationDbContext>());
}
// Your identity and application tables will be created in the database this connect string points to
public ApplicationDbContext()
: base("DefaultConnection", false)
{ }
// define your POCOs here
public virtual DbSet<Foo1> Foo1s { get; set; }
public virtual DbSet<Foo2> Foo2s { get; set; }
.. etc
}

Very simply. In your Web.config
<configuration>
<connectionStrings>
Using code first and Sqlserver:
If you have a local database you use a connection string like so:
<add name="DefaultConnection1" connectionString="Data Source=(LocalDb)\MSSQLLocalDB;
AttachDbFilename=|DataDirectory|\aspnet-WebApplicationMVC-xxxx.mdf;
Initial Catalog=aspnet-WebApplicationMVC-xxxxx;Integrated Security=True"
providerName="System.Data.SqlClient" />
To see the database in visual studio:
If you have a database hosted on an online server:
<add name="DefaultConnection" providerName="System.Data.SqlClient"
connectionString="Data Source=SQLxxxxx;integrated security=false;
Initial Catalog=DB_9D914B_kermit;User Id=DBxxxxx;Password=xxxx;
Trusted_Connection=false;TrustServerCertificate=false;Encrypt=False;
MultipleActiveResultSets=True" />
To see the database in SQL server management studio:
The security attributes of the connection strings can be varied to suit your needs.
