Using Interfaces and Dependency Injection in ASP NET Core 3.1 MVVM Projects

The shared project controllers, Razor Pages, services can be referenced and used in the host web application. There are many more intention actions in Rider for developing object models. Once you’ve created your models, you can build views or Razor pages from scratch, or run scaffolding to build them. Because of Rider’s built-in support for JavaScript, you can use any library you want. And for those of us maintaining legacy ASP.NET code, Rider can open Visual Studio’s solution and project files.

The component won’t have any data until the request from the server comes back, at which point the component may need to render some new comments. You can leave the application running while you continue this tutorial. We’ll be building a simple, but realistic comments box that you can drop into a blog, a basic version of the realtime comments offered by Disqus, LiveFyre or Facebook comments. Especially when building a Blazor Server application, overriding the default can be important.

Navigating ASP.NET Core code

ASP.NET Core 2.0 introduced the concept of Razor Pages and it was a useful addition to the existing features of .NET Core. Razor Pages are similar to the web forms model of ASP.NET web forms. We need to update the Comment component to use Remarkable from either global or window, due to a bug https://remotemode.net/become-a-net-razor-developer/asp-net-core-3-1-razor/ in Remarkable. Also, we need to remove the ReactDOM.render call from the JSX file, as server-side rendering automatically outputs the correct ReactDOM.render call for you. For production use, it is currently recommended to use a tool like Gulp or Webpack to bundle and minify your JavaScript.

ASP.NET Core supports other UI elements like static files, typescript and so on which can also be implemented inside a shared assembly, project. The shared Controller was implemented using the ControllerBase class and the ApiController attribute. TagHelpers enhance HTML tags by adding an attribute that can modify the tag’s output, without having to resort to a scripted syntax like HtmlHelpers or by using JavaScript.

Bundling refers to the practice of combining multiple JavaScript files into a single large file to reduce the number of HTTP requests to load a page. Minification refers to the removal of comments and unnecessary whitespace from JavaScript files to make them smaller. Together, bundling and minification can help to significantly improve the performance of your website. Our application is now feature complete but it feels slow to have to wait for the request to complete before your comment appears in the list.

Server-side rendering enhances the performance of your application since the user will see the initial state immediately. When the user submits the form, we should clear it, submit a request to the server, and refresh the list of comments. To start, let’s listen for the form’s submit event and clear it. When the component is first created, we want to GET some JSON from the server and update the state to reflect the latest data. We’ll use the standard XMLHttpRequest API to retrieve the data. If you need support for old browsers (mainly old Internet Explorer), you can use an AJAX library or a multipurpose library such as jQuery.

Introduction to ASP.NET Core Minimal APIs

Simple Injector offers the Simple Injector ASP.NET Core MVC Integration NuGet package for integration with ASP.NET Core MVC. The project was then added to the host Web API project as a project reference. In addition to the more traditional ways of publishing, Rider supports Docker. Now you can use Rider to Develop ASP.NET Core Applications on Docker, as well for deployment.

• Stop relying on your users to notify you when something is wrong or dig through hundreds of megabytes of log files spread across servers.
• In addition to the more traditional ways of publishing, Rider supports Docker.
• We need to update the Comment component to use Remarkable from either global or window, due to a bug in Remarkable.
• You can override views and pages from a class library in your app by putting the page or view at the same path in your app.
• Let’s see how to reuse this Razor UI Library in another application.
• We can optimistically add this comment to the list to make the app feel faster.

Elmah.io is error logging, uptime monitoring, deployment tracking, and service heartbeats for your .NET and JavaScript applications. Stop relying on your users to notify you when something is wrong or dig through hundreds of megabytes of log files spread across servers. With elmah.io, we store all of your log messages, notify you through popular channels like email, Slack, and Microsoft Teams, and help you fix errors fast. As you may already know, when we add controllers in an MVC application, they are added to the Controllers folder and all the views reside in the Views folder. In the same way, Razor Pages are added conventionally to the Pages folder.
