net Core Web Development

Up to this point in the tutorial, we’ve created a .NET console application and an ASP.NET Core web application. That’s a great start on our Docker journey, but containerization is about distributed systems, right? Let’s add a database to our ASP.NET Core web application and use Docker Compose to create a logical application. To help you set up quickly, you can install the .NET Coding Pack, which includes VS Code, the .NET Software Development Kit, and essential .NET extensions.

Error Handling In Views is essential for creating a robust user experience in ASP.NET Core applications. Proper error handling can prevent the application from crashing and provide meaningful feedback to the user. Lastly, View Components are a more powerful version of partial views, capable of performing logic before returning the HTML result. A layout serves as a template for the application, while partials can be used to segment the view into manageable pieces. ASP.NET Core is based on MVC architecture and provides common libraries to build the Web.

View Components As Exports

This file is applied to all views within its directory and subdirectories. Ensure you have passed a model from your controller’s action method to the view. When an action returns a view, ASP.NET Core will by default look for a Razor file with the same name as the action in a folder named after the controller. When you purchase a Certificate you get access to all course materials, including graded assignments. If you only want to read and view the course content, you can audit the course for free. Board Infinity is a full-stack career platform, founded in 2017 that bridges the gap between career aspirants and industry experts.

Use Visual Studio Code with the C# and F# extensions to get a powerful editing experience with C# IntelliSense, F# IntelliSense (smart code completion), and debugging. View Components in ASP.NET Core are reusable components that can be invoked from any view. They are ideal for creating parts of an application that require some logic to render but are not as complex as a full MVC controller.

Docker Compose and Multiple Containers

Thousands of active developers participating in .NET Core development are improving features, adding new features, and fixing bugs and issues. This article explains what .NET Core is and key features of .NET Core. Our next step is to create a docker-compose.yml file in our project.

They are invoked only when needed, making them efficient for modular design patterns. Save this as a .cshtml file, and reference it in other views as needed. This code defines a section named Scripts that will be rendered in the corresponding @RenderSection(« Scripts ») call within the layout. Sections allow you to insert content into specific areas of a layout from within a view. They are useful for adding page-specific content to placeholders defined in the layout. The ViewBag is a dynamic object that provides a convenient way to add data to the view without requiring a strongly-typed view.

Setting up VS Code for .NET development

In _ViewImports.cshtml, you can also define Tag Helpers and Razor Directives that are needed across many views. In ASP.NET Core, View Import refers to the inclusion of namespaces and directives that can be What is .NET Core used across multiple views within an application. To create a View Component, create a class that inherits from ViewComponent. This class can contain logic to retrieve data and determine what to display.

• In ASP.NET Core, Data Passing between controllers and views is a fundamental part of the MVC framework.
• Create Custom Error Pages to redirect users when an error occurs.
• An independent non-profit organization manages .NET Core called the .NET Foundation.
• The web application uses the Dockerfile we defined in our previous example.
• The Coding Pack can be used as a clean installation, or to update or repair an existing development environment.
• Reading the image’s documentation, we must set an administrator password and accept the end-user license agreement.

The first module lays the foundation of .NET Core, discussing its history, features, differences from other technologies, and how to set up the development environment. Lessons include an introduction to .NET Core, its architecture, and how to utilize .NET CLI for development. The second module offers a deep dive into ASP.NET Core, focusing on developing and configuring web applications. It provides hands-on experience in building a .NET Core application from scratch. By the end of this course, you will have a foundational to advanced understanding of .NET Core, capable of creating dynamic, responsive web applications that run on any platform.

Windows Forms, WPF, UWP, and Xamarin are four major frameworks for building desktop applications. We’ve mentioned volumes in previous sections, and this is a way to create a faster development loop without restarting the container. We would effectively develop and build within our development environment while mounting the project folder as a volume. To define a layout, you place the common HTML structure in a .cshtml file and use the @RenderBody() method to specify where the content of the child views will appear. Dive into the heart of web development with ASP.NET Core Views, the engine that drives the dynamic presentation of content in your applications.

Microsoft’s popular open-source code editor, Visual Studio Code, is not supported on Linux and macOS. VS Code supports the modern needs of code editors, including IntelliSense and debugging. Most third-party editors, such as Sublime, Emacs, and VI, work with .NET Core. According to a report published by TechEmpowers, .NET Core is much faster than any other framework. The same assemblies and libraries can be imported and used on multiple platforms. The assemblies and libraries are built using one of the .NET languages, C#, VB.NET, or F#.
