Developing Page Services

Page Services provide to support Razor pages in order to implement screen logics. Its the same way we create interface and also implementation classes.

Web layer defines that user required actions in page services classes as below way;

public interface IProductPageService    {        Task<IEnumerable<ProductViewModel>> GetProducts(string productName);        Task<ProductViewModel> GetProductById(int productId);        Task<IEnumerable<ProductViewModel>> GetProductByCategory(int categoryId);        Task<IEnumerable<CategoryViewModel>> GetCategories();        Task<ProductViewModel> CreateProduct(ProductViewModel productViewModel);        Task UpdateProduct(ProductViewModel productViewModel);        Task DeleteProduct(ProductViewModel productViewModel);    }public interface ICategoryPageService    {        Task<IEnumerable<CategoryViewModel>> GetCategories();    }

Also implementation located same places in order to choose different implementation at runtime when DI bootstrapped.

public class ProductPageService : IProductPageService{    private readonly IProductAppService _productAppService;    private readonly ICategoryAppService _categoryAppService;    private readonly IMapper _mapper;    private readonly ILogger<ProductPageService> _logger;    public ProductPageService(IProductAppService productAppService, ICategoryAppService categoryAppService, IMapper mapper, ILogger<ProductPageService> logger)    {        _productAppService = productAppService ?? throw new ArgumentNullException(nameof(productAppService));        _categoryAppService = categoryAppService ?? throw new ArgumentNullException(nameof(categoryAppService));        _mapper = mapper ?? throw new ArgumentNullException(nameof(mapper));        _logger = logger ?? throw new ArgumentNullException(nameof(logger));    }    public async Task<IEnumerable<ProductViewModel>> GetProducts(string productName)    {        if (string.IsNullOrWhiteSpace(productName))        {            var list = await _productAppService.GetProductList();            var mapped = _mapper.Map<IEnumerable<ProductViewModel>>(list);            return mapped;        }        var listByName = await _productAppService.GetProductByName(productName);        var mappedByName = _mapper.Map<IEnumerable<ProductViewModel>>(listByName);        return mappedByName;    }}

Upload Requirements

  • Style Kits must include JSON settings file(s), a CSS file, and an XML demo content file.
  • Any images referenced within the XML demo file must also be hosted on a live demo server so that they are able to be imported automatically along with the rest of the demo content.
  • Images and graphics files used by the Style Kit must be included in the item to allow users to upload the images manually if import via the xml and JSON files fails. All images should be free to distribute and meet the requirements for including assets.
  • Multiple sets of JSON, CSS, and XML files may be included in the item as variations of the Style Kit (e.g. alternate layouts, color schemes, etc).
  • The LayersWP theme should not be included in the child theme zip file. Instead a prominent link to the LayersWP download should be displayed in the Item Description and the documentation.

Item must have the following at the top of their description to help buyers know that the item works with Layers:

<a href=""><img src=""></a>



One library for all UX patterns. Slider, Popups, Accordeon, Menu, Parallax, (Touch) Gestures, etc.

Repository implementations of Infrastructure layer has Entity Framework Core context, wrapper class and Repositories which perform db operations via EF Context object.

public class ProductRepository : Repository<Product>, IProductRepository    {        public ProductRepository(AspnetRunContext dbContext) : base(dbContext)        {        }        public async Task<IEnumerable<Product>> GetProductListAsync()        {            // return await GetAllAsync();            var spec = new ProductWithCategorySpecification();            return await GetAsync(spec);        }        public async Task<IEnumerable<Product>> GetProductByNameAsync(string productName)        {            var spec = new ProductWithCategorySpecification(productName);            return await GetAsync(spec);        }        public async Task<IEnumerable<Product>> GetProductByCategoryAsync(int categoryId)        {            return await _dbContext.Products                .Where(x => x.CategoryId==categoryId)                .ToListAsync();        }    }public class CategoryRepository : Repository<Category>, ICategoryRepository    {        public CategoryRepository(AspnetRunContext dbContext) : base(dbContext)        {                    }        public async Task<Category> GetCategoryWithProductsAsync(int categoryId)        {                        var spec = new CategoryWithProductsSpecification(categoryId);            var category = (await GetAsync(spec)).FirstOrDefault();            return category;        }    }

As you can see that these implementation classes inherit from base Repository.cs in order to use Entity Framework Core dbContext object and use benefits from db abstractions.

Класс Model

Как правило, вы будете использовать класс для определения внутренних вычислительных блоков и будете использовать класс для определения внешней модели — объекта, который вы будете обучать.

Например, в модели ResNet50 у вас будет несколько блоков ResNet, создающих подкласс , и одна охватывающая всю сеть ResNet50.

Класс имеет тот же API, что и , со следующими отличиями:

  • Он предоставляет встроенные циклы обучения, оценки и прогнозирования ( , , ).
  • Он предоставляет список своих внутренних слоев через свойство .
  • Он предоставляет API сохранения и сериализации ( , …)

Фактически, класс соответствует тому, что мы называем в литературе «слоем» (как в «сверточном слое» или «рекуррентном слое») или как «блоком» (как в «блоке ResNet» или «начальном блоке». ).

Между тем, класс соответствует тому, что в литературе называется «моделью» (как «модель глубокого обучения») или «сетью» (как «глубокая нейронная сеть»).

Итак, если вам интересно, «что мне следует использовать: класс или класс ?», Спросите себя: нужно ли мне вызывать для этого ? Мне нужно будет вызвать для этого функцию ? Если да, выбирайте . Если нет (либо потому, что ваш класс — это просто блок в более крупной системе, либо потому, что вы сами пишете обучающий и сохраняете код), используйте .

Например, мы могли бы взять наш приведенный выше пример мини-реснета и использовать его для создания которую мы могли бы обучать с помощью и которую мы могли бы сохранить с помощью :

Application Layer Components

Beyond this developments, also there are main components should be handled in Application layer;

  • Authorization Management
  • Validation Management
  • Session Management
  • Notification Management
  • Exception Management

So in this layer we have these cross-cutting activities which provide to manage your application. You will authorize your application in this layer, you should apply your validations in here, you should manage application session and publish notifications from application layer with exception management.

All validation , authorization, logging, exception handling etc. — this kind of cross cutting activities should be handled by these classes.

Web Layer

Development of UI Logic with implementation. Interfaces drives business requirements and implementations in this layer. The application’s main starting point is the ASP.NET Core web project. This is a classical console application, with a public static void Main method in Program.cs. It currently uses the default ASP.NET Core project template which based on Razor Pages templates. This includes appsettings.json file plus environment variables in order to stored configuration parameters, and is configured in Startup.cs.

The last layer is UI layer, so in this layer we consumed all other layers. Lets start with the ViewModel classes. This classes you can think that imagine of Page components and what is the required data of page.

public class ProductViewModel : BaseViewModel    {        public string ProductName { get; set; }        public string QuantityPerUnit { get; set; }        public decimal? UnitPrice { get; set; }        public short? UnitsInStock { get; set; }        public short? UnitsOnOrder { get; set; }        public short? ReorderLevel { get; set; }        public bool Discontinued { get; set; }        public int? CategoryId { get; set; }        public CategoryViewModel Category { get; set; }    } public class CategoryViewModel : BaseViewModel    {        public string CategoryName { get; set; }        public string Description { get; set; }    }

Process Management

Every app in Android runs in a process. The Kernel is also responsible for managing processes. This means it’s responsible for creating, pausing, stopping, shutting, or killing down processes.

The Kernel enables various functionalities such as running multiple processes at the same time, communicating between processes, running processes in the background, and so on.

As each process requires its own memory space to function correctly, the Kernel ensures that memory spaces allotted for each process are protected from other processes. It also ensures that resources like RAM allotted to processes are freed up when the processes are shut down.

The Linux Kernel is also responsible for distributing work to the processors present in the device. This makes it possible to maximize the performance of devices with multiple cores as different apps will have processes being run on a different core.

The Linux Kernel does more task under the hood including enforcing security.


  • Android architecture is organized in layers.
  • Each layer solves a unique set of problems.
  • End-users interact with apps on the Application layer
  • Application developers develop apps to be used on the Application layer. They do so using tools and abstractions provided by the Application Framework.
  • Android Framework layer simplifies access to low-level components by creating an API over native libraries.
  • Android Runtime and Core-Libraries use low-level languages together with optimizations for mobile devices. This ensures code written by application developers runs smoothly despite Android device constraints.
  • At the bottom of the Android software stack is the Linux kernel. It interfaces with the hardware components common in Android devices.

Flow interactors

  • , , classes
  • Interacts with user or system events, such as gestures or the app state changes
  • Trigger

A dynamic workflow emerges

Using , in conjunction with the layered modular foundation, a flow’s features, sequencing, transitions and dependencies are defined in an isolated framework. It knows nothing of the app it is part of, and whether it leads to another flow. It knows only the frameworks it has inherited.

This results in the emergence of a dynamic workflow — entire flows with features can be prototyped, built and tested, independently from your main app and from other flows.

Swapping out components, features, sequences, transitions, and interactors becomes relatively painless. Even constructing a test app to validate assumptions is done by simply linking dependencies into a new target and running it.

Everything is recomposable, reusable and testable all of the time.

Developing Razor Pages

The final part of UI implementation is Razor Pages. So we should create a Product and Category folder into Pages folder. And in these folder, create cshtml razor pages with Index-Create-Edit-Delete pages in order to building web pages.

Lets create with Index page;

Html Part;

@page@model AspnetRun.Web.Pages.Product.IndexModel@{    ViewData = "Index";}<h1>Product List</h1><form method="get">    <div class="form-group">        <div class="input-group">            <input type="search" class="form-control" asp-for="SearchTerm" />            <span class="input-group-btn">                <button class="btn btn-default">                    Search                </button>            </span>        </div>    </div></form><p>    <a asp-page="Create">Create New</a></p><table class="table table-hover">    <thead>        <tr>            <th scope="col">Id</th>            <th scope="col">Name</th>            <th scope="col">UnitPrice</th>            <th scope="col">Category</th>            <th scope="col">Action</th>        </tr>    </thead>    <tbody>        @foreach (var product in Model.ProductList)        {            <tr>                <th scope="row">@product.Id</th>                <td>@product.ProductName</td>                <td>@product.UnitPrice</td>                <td>@product.Category.CategoryName</td>                <td>                    <a class="btn"                       asp-page="./Details"                       asp-route-productId="@product.Id">                        Details                    </a>                    <a class="btn"                       asp-page="./Edit"                       asp-route-productId="@product.Id">                        Edit                    </a>                    <a class="btn"                       asp-page="./Delete"                       asp-route-productId="@product.Id">                        Delete                    </a>                </td>            </tr>        }    </tbody></table>

IndexModel.cs ;

public class IndexModel : PageModel    {        private readonly IProductPageService _productPageService;        public IndexModel(IProductPageService productPageService)        {            _productPageService = productPageService ?? throw new ArgumentNullException(nameof(productPageService));        }        public IEnumerable<ProductViewModel> ProductList { get; set; } = new List<ProductViewModel>();                public string SearchTerm { get; set; }        public async Task<IActionResult> OnGetAsync()        {            ProductList = await _productPageService.GetProducts(SearchTerm);            return Page();        }    }

При желании вы можете включить сериализацию на своих слоях

Если вам нужно, чтобы ваши пользовательские слои были сериализуемыми как часть функциональной модели , вы можете дополнительно реализовать метод :

{'units': 64}

Обратите внимание, что метод базового класса принимает некоторые аргументы ключевого слова, в частности и. Рекомендуется передать эти аргументы родительскому классу в и включить их в конфигурацию слоя:

{'name': 'linear_8', 'trainable': True, 'dtype': 'float32', 'units': 64}

Если вам нужна большая гибкость при десериализации слоя из его конфигурации, вы также можете переопределить метод класса . Это базовая реализация :

The following are the layers that compose the Android architecture as labeled on the diagram:

  1. Application
  2. Application Framework
  3. Android Runtime and Core Libraries
  4. Linux Kernel

Developing an operating system for mobile devices comes with a set of challenges. Using this layered architecture ensures that different problems are broken down and solved at different levels.

A layered architecture helps separate concerns and ensure android software developers don’t have to deal with low-level problems at every turn. They can instead focus on delivering business value concerned with the layer they’re working on.

Developers working on making apps don’t have to worry about the application framework implementation. That work is left for the system developers working on the Application framework.

The Application Framework developers work on developer experience and don’t have to worry about the low-level drivers. Low-level system engineers can focus completely on low-level components such as Bluetooth or Audio drivers and the like.

Android’s layered structure makes it possible to apply updates with bug fixes or improvements to each layer on its own. This ensures that changes across layers don’t interfere with each other. This makes it possible for people working at a different level of the OS to work with obstructing each other as new updates and releases are done.


This is primarily a maintenance release, but one tweak was made.

Tweak: Changed name of meta box title

Release to downgrade Featherlight verison until all bugs are worked out.

Dev: Updated Featherlight to 1.7.13


This is primarily a maintenance release, but one new feature has been added. Display the option to disable the lightbox in Gutenberg!

Here’s a full list of what’s changed since the last release:

  • Feature: Add back metabox in sidebar
  • Dev: Updated Featherlight to


While primarily a maintenance release, one new feature has been added. WP Featherlight now supports Gutenberg galleries.

Here’s a full list of what’s changed since the last release:

  • Feature: Gutenberg support
  • Tweak: General code cleanup in plugin
  • Dev: Updated Featherlight to
  • Change of ownership


This is primarily a maintenance release, but one new feature has been added. HTML in captions is now supported!

Here’s a full list of what’s changed since the last release:

  • Feature: Allowed HTML to be displayed in lightbox image captions
  • Dev: Updated Featherlight to
  • Dev: Updated jQuery Detect Swipe to


Thanks to some changes implemented in the core featherlight script, the accessibility of WP Featherlight is now significantly improved. Lightboxed elements now have more appropriate focus management for screen readers and the close button is more accessible.

This update also fixes a potential plugin compatibly problem in the WordPress admin. In version 1.0, it was possible under unusual circumstances for the plugin to throw a fatal error when attempting to add the disable checkbox to the publish metabox.

  • Tweak: Improved accessibility (accessible close button, better focus management)
  • Fix: Prevented a fatal error that could happen when another plugin unsets the WP_Post object on the publish metabox.
  • Dev: Updated Featherlight to


Even though this is a major version change, this is primarily a maintenance release. The reason for the jump to 1.0.0 is because we’ve changed some code which could break backwards compatibility with custom extensions and integrations.

If you’re just using the plugin on your site and haven’t customized it or paid anyone to customize it for you, you should be able to update without any issues.

If you’re a developer and have written custom code extending the PHP side of WP Featherlight, be sure to test your code before updating.

Under the hood, we’ve deprecated some internal methods which could potentially break custom code which extends WP Featherlight. The changes are primarily limited to class initialization, so unless you were doing something specific to that, it’s unlikely that you’ll run into issues.

  • Tweak: Improved transition between images within galleries
  • Tweak: Moved our disable lightbox checkbox into the publish meta box to streamline the admin
  • Tweak: Made styles more aggressive to ensure elements look consistent across different themes by default
  • Fix: Reduced false positives for URLs that use image extensions but don’t actually link to an image
  • Dev: Updated Featherlight to
  • Dev: Updated jQuery Detect Swipe to
  • Dev: Deprecated some internal methods
  • Dev: Reorganized how classes are instantiated and plugin actions are fired

How is RRO different from Layers?

Layers is a collective effort by a team called BitSyko. As of Lollipop 5.1, Layers basically expands upon the stock RRO functionality to enable more complex resource switching and allowing themes to take control of more elements than was possible with the stock RRO.

This give rise to two issues. One is that ROM makers need to add code to enable Layers in their roms as the complete functionality of Layers (not to be confused with stock RRO) requires changes to the stock Lollipop RRO.

Second issue is that not all Layers themes will work with Stock RRO. Only simpler themes which do not make use of any complex features can work on stock RRO.

Here’s what XDA Recognized Developer and creator of Layers, sykopompos, has to say regarding enabling Layers support on stock Android M (Dev Preview):

In simple words, Layers and RRO are not interchangeable all the time. Layers themes working completely “bug-free” on Stock RRO will be a happy coincidence, but for most XDA users, a little experimentation is never out of the question.

Of course, this assumes that the RRO implementation remains the same between the Dev Preview and the Android M Stable Release. A lot of things can change regarding both RRO and Layers, so this is how the situation currently stands.
