Reading this MSDN article titled "Working with ObjectSet (Entity Framework)" It shows two examples on how to add a Product.. one for 3.5 and another for 4.0.

http://msdn.microsoft.com/en-us/library/ee473442.aspx

Through my lack of knowledge I am possibly completely missing something here, but i never added a Product like this:

   //In .NET Framework 3.5 SP1, use the following code: (ObjectQuery)
   using (AdventureWorksEntities context = new AdventureWorksEntities())
   {
      // Add the new object to the context.
      context.AddObject("Products", newProduct);
   } 

   //New in .NET Framework 4, use the following code: (ObjectSet)
   using (AdventureWorksEntities context = new AdventureWorksEntities())
   {
      // Add the new object to the context.
      context.Products.AddObject(newProduct);
   }

I would not have done it either way and just used:

   // (My familiar way)
   using (AdventureWorksEntities context = new AdventureWorksEntities())
   {
      // Add the new object to the context.
      context.AddToProducts(newProduct);
   }

What's the difference between these three ways?

Is "My way" just another way of using an ObjectQuery?
