C# Blazor
Using Blazor
C# Blazor builds interactive web UIs with C# and WebAssembly.
Introduction to Blazor
Blazor is a framework for building interactive web applications using C#, Razor, and HTML. Unlike traditional JavaScript-based frameworks, Blazor allows you to write client-side logic using C# and run it in the browser via WebAssembly.
Setting Up a Blazor Project
To get started with a Blazor application, you need to have the .NET Core SDK installed on your machine. You can create a new Blazor project using the following command in your terminal:
This command creates a new Blazor Server application in a folder named MyBlazorApp. Blazor Server apps host Razor components on the server and handle UI interactions over a SignalR connection.
Understanding Blazor Components
In Blazor, a component is a self-contained unit of UI, such as a page, dialog, or form. A component is defined using a combination of C#, HTML, and Razor syntax. Blazor components can be reused throughout the application.
The above example shows a simple counter component. It uses an HTML button to increment a count each time it's clicked. The @code block contains the C# logic required for the component.
Blazor Hosting Models
Blazor supports multiple hosting models:
- Blazor Server: Components are executed on the server and UI updates are sent over a SignalR connection.
- Blazor WebAssembly: Components run directly in the browser on WebAssembly, making the app independent of server interactions after the initial load.
Benefits of Using Blazor
Blazor provides several advantages:
- Full-Stack C# Development: Developers can use C# for both client-side and server-side logic, reducing the need to switch languages.
- Reusable Components: Razor components can be reused, reducing duplication and improving maintainability.
- Rich .NET Ecosystem: Leverage the existing .NET libraries and tools, which are mature and well-supported.
