Sessionstate
I have been reading a little about sessionstate in other books and have only recently got this one.
Is sessionstate and the likes used in this book or it other techniques used?
I want to make a shoppingcart application.
If so, where can I find it?

Nope; it's mentioned once or twice, but it's not used in any of the examples.
Cheers,

So can you make a shopping-cart with some other technique you describe?

Probably, yes.... You can store the cart in the database and store a unique ID in a cookie.
However, the book doesn't address shopping carts explicitly, so you may want to look elsewhere as well for a more detailed description of building a cart. For instance, you could download the code for my book ASP.NET 2 Instant Results that feature a cart and see if you like it ( VB only).
Cheers,
Imar

Ok, but that´s not the preferred way I suppose?
My question was really if there was a new better or preferred way to make a shoppingcart. Maybe some new technique in .Net 4.

It all depends. It's not uncommon to do so, as it scales better. Server memory is limited so on busy websites, storing the cart in the database enables you to serve more users, at the cost of decreased performance.

Not in the framework directly. The same principle (session state, a database or some other durable mechanism) is still the way to go.
You may want to search Google for ready-made shopping carts (commercial and open source) or look into ready-made CMS and eCommerce systems such as Dynamicweb.
Cheers,
Imar
