In this tutorial we will go through a process of building a sample shopping cart with real time capabilities. On top of that, we’ll also throw in a real time admin order overview.
The technologies used will include:

- ASP.NET Web API – as an API to retrieve data and send orders to the server side
- SignalR – to notify interested parties in changes to the item stock quantities & order status
Since the topic of building a functional e-commerce solution is obviously extremely broad, we will take a few simplifications, which will allow us to focus our attention on the real time aspects of the cart and avoid distractions. We will treat security (user login/logout) and data persistence (we’ll just store the data in memory) as out of scope.
