Set the Target Framework to. In the Project Name field, name the app WebApplication1. Run the app with Start Debugging to run the app with the debugger. On the Counter page, select the Click me button to increment the counter without a page refresh.It will also show you how to integrate your Blazor application with Auth0 in order to secure it.
Following the steps described in this tutorial, you will end up building two versions of a simple Web application. You can find the full code in this GitHub repository.
Blazor has been gaining in popularity lately, especially after the release of. NET Core 3. There is great interest around it and Microsoft is betting a lot on its future. But what is Blazor exactly? Blazor is a programming framework to build client-side Web applications with. It allows. Developing client-side applications with Blazor brings a few benefits to. NET developers:. In a nutshell, Blazor promises. NET developers to let them build client Web applications with the development platform they are comfortable with.
These are called hosting models.Downthemall linux
NET Core application. The UI is sent to the browser, but UI updates and event handling are performed on the server side. This is similar to traditional Web applications, but the communication between the client side and the server side happens over a SignalR connection. The following picture gives you an idea of the overall architecture of the Blazor Server hosting model:. The Blazor Server hosting model provides a few benefits, such as a smaller download size of the client app and the compatibility with not recent browsers.
However, it has some drawbacks, like a higher latency due to the roundtrip between the client and the server for most user interactions and the challenging scalability in high traffic scenarios.One of my secret dreams is coming true: we will soon be able to write C code and have it run in the browser! This is due to a formerly-experimental, but now officially supported! In this tutorial, we'll learn what Blazor is, and build a sample app to demonstrate how to use it.
I swear this is not a dream. Let's get going! Blazor is an web framework that, in short, allows you to write C and HTML to create client-side single-page applications.
In practice, it looks very similar to Razor Pages applications. The written C is then compiled down to a standard called WebAssemblywhich allows for use on all modern browsers. In theory, we are now able to create client-side applications using C and.
NET Core 2. Microsoft has already written up a nice set of instructions on how to do this, and it is over on the Microsoft Docs site. Follow the steps in "prerequisites" and then come back here. Our demo sounds an awful lot like something on that site, but it isn't quite the same. As I do with most of my code-focused posts, I created a sample application that is hosted over on GitHub and demonstrates the code in this post.
Check it out! This is a fully client-side application, running from C code that has been transpiled to Web Assembly. If you try switching to the Counter or Fetch Data example pages, you'll see how snappy it is, and how nice it feels to navigate around it. But we didn't come here to see the sample app that Visual Studio can generate for us.
We came here to build our own page. Let's do that. We're going to add a new page to this sample project and make it a very simple To-Do list. To do that, we're going to need three parts. The first one is the easiest. Let's add a new JSON file called todoitems. The file looks like this:. Note: we are using GUIDs for the ID field because it makes it much easier to generate new ones, since we don't have a database and partially because I'm lazy.
Now we need a ToDo.GitHub is home to over 40 million developers working together to host and review code, manage projects, and build software together.

Blazor apps are based on components. A component in Blazor is an element of UI, such as a page, dialog, or data entry form. The component class is usually written in the form of a Razor markup page with a. Components in Blazor are formally referred to as Razor components. The following Razor markup demonstrates a component Dialog. The dialog's body content ChildContent and title Title are provided by the component that uses this component in its UI.
OnYes is a C method triggered by the button's onclick event. HTML elements specify components, and a tag's attributes pass values to a component's properties.
In the following example, the Index component uses the Dialog component. When this component is used in the app, IntelliSense in Visual Studio and Visual Studio Code speeds development with syntax and parameter completion.
Components render into an in-memory representation of the browser's Document Object Model DOM called a render treewhich is used to update the UI in a flexible and efficient way.
Blazor Server is supported in ASP. NET Core 3. Blazor WebAssembly is a single-page app framework for building interactive client-side web apps with.
The size of the published app, its payload sizeis a critical performance factor for an app's useability. A large app takes a relatively long time to download to a browser, which diminishes the user experience.
Blazor WebAssembly optimizes payload size to reduce download times:. Blazor decouples component rendering logic from how UI updates are applied.
NET Core app. UI updates are handled over a SignalR connection. The runtime handles sending UI events from the browser to the server and applies UI updates sent by the server back to the browser after running the components.
ASP.NET Core Blazor templates
Dynamic rendering logic for example, loops, conditionals, expressions is added using an embedded C syntax called Razor. The name of the generated. NET class matches the file name. Members of the component class are defined in an code block. In the code block, component state properties, fields and methods are specified for event handling or for defining other component logic. These members are then used as part of the component's rendering logic and for handling events.
Modify the C logic of the Counter component to make the count increment by two instead of one. Rebuild and run the app to see the changes.Dominating statue of braccus rex
Select the Click me button. The counter increments by two.
Components can also have parameters. Component parameters are defined using public properties on the component class with the [Parameter] attribute. Use attributes to specify arguments for a component in markup. Set the value to increment the counter by ten. Reload the Index component. The counter increments by ten each time the Click me button is selected.
The counter in the Counter component continues to increment by one. The page directive at the top of the Counter. Without the page directive, a component doesn't handle routed requests, but the component can still be used by other components. An instance of the service is available throughout the app via dependency injection DI :. The inject directive is used to inject the instance of the WeatherForecastService service into the FetchData component.
The FetchData component uses the injected service, as ForecastServiceto retrieve an array of WeatherForecast objects:. If working with a Blazor WebAssembly app, HttpClient is injected to obtain weather forecast data from the weather.
