+* Notice, this class is derieved from the `BooksAppServiceBase` class and implements the `IBooksAppService`.
+* Thus, ABP Suite only modifies the `BooksAppServiceBase` class and implements the necessary services in each generation, but does not generate the files with the `*.Extended` postfixes and let you implement your own custom code.

 In this tutorial, you created the bookstore application without needing to write a single line of code with ABP Suite. Then, in this last part, you have written custom code in the specified hookpoints and it did not override by ABP Suite.
