Question

Hi I am using Entity framework code first for the first time and I am having trouble generating the tables.I have created an empty database in my App_Data in an MVC3 application.
This are the models I have created:

 public class Brand {
    public int BrandId { get;set; }
    public string BrandName { get;set; }
}

public class Model
{
    public int ModelId { get;set; }
    public Brand BrandId { get;set; }
    public Category CategoryId { get;set; }
    public string ModelName { get;set; }
}

public class Category
{
    public int CategoryId { get;set; }
    public string CategoryName { get;set; }
}

This is the dbContext:

public class CarsEntities : DbContext{
    public DbSet<Brand> Brands { get;set; }
    public DbSet<Model> Models { get;set; }
    public DbSet<Category> Categories {get;set;} 
}

And this is the connectionString in web.config:

<connectionStrings>
      <add name="CarsEntities" connectionString="Data Source='D:\Projects IDE\Visual Studio\MyWork\Websites\SellCars\SellCars\App_Data\Cars.sdf'" providerName="System.Data.SqlClient" />      
 </connectionStrings>

Now I have initialized CarsEntities in my HomeController but it seems that none of the tables get generated.What am I doing wrong?

I think the problem comes in your

webcofig 

here is if you want to use the db as a file like mdf file database file
specifically in dtasource

       `<add name="CarsEntities"  connectionString="data source=.\SQLEXPRESS; Integrated
 Security=SSPI;AttachDBFilename=|yourDirectoryDirectory|\thenameofyourdb.mdf;User
 Instance=true"  providerName="System.Data.SqlClient" /`>
