+# ASP.NET Core DevExtreme Example
+
+## Installation
+
+Download the example and use Visual Studio 2022 (or later) or Visual Studio Code to open the project. This project targets .NET 8.0. 
+
+## Client-side resources and bundling
+
+This project uses [NPM](https://www.npmjs.com/) and [Gulp.js](https://gulpjs.com/) to install client-side libraries. The project restores NPM packages before the first build. Then, Gulp bundles required scripts and CSS files into the resulting package during the first and every next build.
+
+The project includes:
+- DevExtreme 24.2.3
+- DevExtreme.AspNet.Core 24.2.*
+- DevExtreme.AspNet.Data 5.*
+- jQuery 3.7.1
+- Bootstrap 5.3.3 
+
+The resulted bundles will be located in the `wwwroot` folder:
+* `css/vendor.css` - a file with all CSS styles.
+* `css/icons` and `css/fonts` - folders that contain fonts and icons for DevExtreme themes.
+* `js/vendor.js` - a file that contains all scripts.
+
+The default bundle includes jQuery, Bootstrap, and DevExtreme.
+
+### Add more 3rd-party libraries for additional features/components 
+
+The main logic is located in the the `gulpfile.js` file at the root application level. The file contains two tasks:
+
+* the `add-resources` task  
+
+    * copies JavaScript files located in the `scripts` array and adds them to `vendor.js`. The script bundle is moved to `wwwroot\js`.
+    * copies CSS styles located in the `styles` array and merges them into the `vendor.css` bundle. Then, this bundle is moved to `wwwroot\css`
+    * copies DevExtreme `fonts` and `icons` folders from NPM  to `wwwroot\css`
+
+*  the `clean` task removes all previously created files (`vendor.js` and `vendor.css`) and folders (`icons` and `fonts`)
+
+If you need to include more features, you can uncomment one of the following sections:
+
+* Gantt - scripts and styles for [dxGantt](https://js.devexpress.com/DevExtreme/Guide/UI_Components/Gantt/Getting_Started_with_Gantt/).
+* Diagram - scripts and styles for [dxDiagram](https://js.devexpress.com/DevExtreme/Guide/UI_Components/Diagram/Getting_Started_with_Diagram/).
+* Export  - scripts and styles for the exporting feature: [Export Data to Excel](https://js.devexpress.com/DevExtreme/Guide/UI_Components/DataGrid/Getting_Started_with_DataGrid/#Export_Data). 
+* HtmlEditor - scripts and styles for [dxHtmlEditor](https://js.devexpress.com/DevExtreme/Guide/UI_Components/HtmlEditor/Overview/).
+* Full Bundle - scripts and styles for all above mentioned features/components.  
+
+## Code
+
+Take a look at the following files of this example to see the required code:
+
+**Controllers:**
+- `Controllers/HomeController.cs` - Main controller with Index action
+- `Controllers/SampleDataController.cs` - API controller for sample data
+
+**Models:**
+- `Models/SampleData.cs` - Sample data model
+- `Models/SampleOrder.cs` - Sample order model
+
+**Views:**
+- `Views/Home/Index.cshtml` - Main page with DevExtreme components
+- `Views/Shared/_Layout.cshtml` - Layout template
+- `Views/_ViewImports.cshtml` - Global imports
+- `Views/_ViewStart.cshtml` - View start configuration
+
+**Configuration:**
+- `Program.cs` - Application entry point
+- `Startup.cs` - Service configuration
+- `gulpfile.js` - Build automation
+- `package.json` - NPM dependencies
+- `ASP.NET Core.csproj` - Project file
+
+## Development server
+
+Use the Visual Studio `Run (F5)` command or `dotnet run` command to run the project. The application will be available at `https://localhost:5001` (HTTPS) or `http://localhost:5000` (HTTP).
+
+## Further help
+
+You can learn more about the ASP.NET Core components' syntax in our documentation: [Concepts](https://docs.devexpress.com/AspNetCore/400574/devextreme-based-controls/concepts/razor-syntax)
+The client-side API is based on jQuery [jQuery documentation](https://api.jquery.com/) and described in the following topics: 
+* [Get and Set Properties](https://js.devexpress.com/DevExtreme/Guide/jQuery_Components/Component_Configuration_Syntax/#Get_and_Set_Properties)
+* [Call Methods](https://js.devexpress.com/DevExtreme/Guide/jQuery_Components/Component_Configuration_Syntax/#Call_Methods)
+* [Get a UI Component Instance](https://js.devexpress.com/DevExtreme/Guide/jQuery_Components/Component_Configuration_Syntax/#Get_a_UI_Component_Instance)
+
+To get more help on DevExtreme submit an issue in the [Support Center](https://supportcenter.devexpress.com/ticket/create)
