Building a Blazor App
C# Blazor app creates interactive UIs with WebAssembly.
Introduction to Blazor and WebAssembly
Blazor is a framework for building interactive web user interfaces using C#. It allows developers to create a rich, client-side experience using .NET and WebAssembly, a binary instruction format that enables high-performance applications on the web.
With Blazor, you can write your entire application in C#, share code between the client and server, and leverage the full power of .NET.
Setting Up a Blazor Project
To get started with a Blazor project, you will need to have the .NET SDK installed on your machine. You can create a new Blazor project using the following command:
This command creates a new Blazor WebAssembly project in a directory named MyBlazorApp. Navigate into the directory to begin exploring your project:
Exploring the Project Structure
The Blazor project structure consists of several key components:
wwwroot: Contains static assets like CSS and JavaScript files.Pages: Holds the main Razor components (.razor files) that define your UI.Program.cs: Configures and launches the Blazor application.
Let's take a look at a simple Razor component.
Creating a Simple Razor Component
Razor components are the building blocks of Blazor applications. They are .razor files that combine C# and HTML markup. Here's an example of a simple Razor component:
In this example, a button is rendered that toggles a message when clicked. The @onclick directive binds the button's click event to the ShowMessage method, which toggles the showMessage boolean. This boolean determines if the message "Hello, Blazor!" is displayed.
Running Your Blazor Application
To run your Blazor application, use the dotnet run command:
After running this command, navigate to https://localhost:5001 in your web browser. You should see your Blazor app up and running, allowing you to interact with the UI you created.
