You now have a backdrop of knowledge, if you didn't already know it all. We explained the terminology in this chapter so that the terms will be clear to you throughout. It's now time to get concrete and actually start applying what we've discussed. Although this chapter mentions quite a few concepts and they might be new to you, don't worry as we'll revisit them throughout the book and gain more knowledge about them as we go along. The next chapter will start out with a simple sample, showing the very basics of SignalR so that you get the feeling of what it is and how its APIs are. It will also establish the basics of the project that we will be working on throughout this book, with ASP.NET and AngularJS throwing bootstrap into the mix as well.
