This is the second part of the ASP.NET Core {{UI_Value}} tutorial series. All parts:
In this tutorial series, you will build an ABP based web application named `Acme.BookStore`. This application is used to manage a list of books and their authors. It is developed using the following technologies:
* [Part I: Creating the project and book list page](part-1.md)
* **Part II: Creating, updating and deleting books (this tutorial)**
* [Part III: Integration tests](part-3.md)
* **{{DB_Text}}** as the ORM provider.
* **{{UI_Value}}** as the UI Framework.
*You can also watch [this video course](https://amazingsolutions.teachable.com/p/lets-build-the-bookstore-application) prepared by an ABP community member, based on this tutorial.*
This tutorial is organized as the following parts;
- [Part I: Creating the project and book list page](part-1.md)
- **Part-2: Creating, updating and deleting books (this part)**
- [Part-3: Integration tests](part-3.md)

### Creating a new book

* This class is derived from the `BookStorePageModel` instead of standard `PageModel`. `BookStorePageModel` inherits the `PageModel` and adds some common properties & methods that can be used in your page model classes.
* This class is derived from the `BookStorePageModel` instead of standard `PageModel`. `BookStorePageModel` indirectly inherits the `PageModel` and adds some common properties & methods that can be shared in your page model classes.
* `[BindProperty]` attribute on the `Book` property binds post request data to this property.
* This class simply injects the `IBookAppService` in the constructor and calls the `CreateAsync` method in the `OnPostAsync` handler.
* It creates a new `CreateUpdateBookDto` object in the `OnGet` method. ASP.NET Core can work without creating a new instance like that. However, it doesn't create an instance for you and if your class has some default value assignments or code execution in the class constructor, they won't work. For this case, we set default values for some of the `CreateUpdateBookDto` properties.

* This modal uses `abp-dynamic-form`[tag helper](../UI/AspNetCore/Tag-Helpers/Dynamic-Forms.md) to automatically create the form from the `CreateBookViewModel` model class.
* `abp-model` attribute indicates the model object where it's the `Book` property in this case.
* `data-ajaxForm` attribute sets the form to submit via AJAX, instead of a classic page post.
* `abp-form-content` tag helper is a placeholder to render the form controls (it is optional and needed only if you have added some other content in the `abp-dynamic-form` tag, just like in this page).

Now, you can **run the application** and add new books using the new modal form.
