Entity Framework code first database is not created

Hello,

I am currently working on this tutorial to learn ASP.net https://docs.microsoft.com/en-us/aspnet/web-forms/overview/getting-started/getting-started-with-aspnet-45-web-forms/create_the_data_access_layer but the stuff with my database is not working. I.e. when I run the website the database is not created automatically. Instead of creating a default database as described in the tutorial I would like to use my local SQL Server 2017. So what I did to do this is use another connection string and refer to it from the context class:

public class ProductContext : DbContext
    {
        public ProductContext() : base("name=WingtipToys")
        {
        }
        public DbSet<Category> Categories { get; set; }
        public DbSet<Product> Products { get; set; }
    }

<connectionStrings>
    <add name="DefaultConnection" connectionString="Data Source=(LocalDb)\MSSQLLocalDB;AttachDbFilename=|DataDirectory|\aspnet-WingtipToys-20171201071611.mdf;Initial Catalog=aspnet-WingtipToys-20171201071611;Integrated Security=True"
      providerName="System.Data.SqlClient" />
    <add name="WingtipToys"
      connectionString="Data Source=(local);Initial Catalog=wingtiptoys;Integrated Security=sspi"
      providerName="System.Data.SqlClient" />

</connectionStrings>

But for some reason this is not working. I also tried if I can connect programatically and it worked fine.

SqlConnection sqlConnection = new SqlConnection();
sqlConnection.ConnectionString = "Data Source=(local);Initial Catalog=wingtiptoys;Integrated Security=sspi";
sqlConnection.Open();

I am using sspi as I want to do Windows Authentification.

So I don't understand why the Entity Framework isn't doing what it is supposed to do. Unfortunately I also don't see any information in the output window of Visual Studio so I have no idea what's going on. When I look into the profile window on my SQL Server Management Studio I see that nothing is done.

Has anyone an idea what else I can try?

Best regards

Thomas
