What is Blazor for Developers ?


We’ll talk about the amazing Blazor technology in this article. Personally, I found that working on this incredible technology made development work much more interesting and productive. We will discuss Blazor’s general features in this article, including:

  • Describe Blazor
  • why Blazor should be used
  • How to begin using Blazor
  • Blazor Server & Blazor WebAssemby

Describe Blazor

A Blazor application is constructed from web building blocks like HTML, CSS, and C# code. Utilizing an ASP.NET feature called Razor Components, Blazor applications are created. These are the HTML and C#-based files.

How Does Blazor Work? and What Is Blazor?

A button on the razor component calls the onclick method IncrementCount (). This is how the code in Blazor applications looks, but we can also separate the code and UI on different pages. You can nest your components, which are reusable building blocks that you can use in your application.

Why ought we to employ Blazor?

Assembly creation occurs during the building process of a Blazor application, among other things. You can build a Blazor Component Library and reuse it because these DLLs are.NET Standard DLLs that you can use in any other compatible application. All of your application’s components, including system dependencies like the system, are contained in these DLLs. DLLs.

These DLLs can be run in the browser using the.NET runtime. The WebAssembly file extension for this.NET runtime is.wasm, and it is compiled into WebAssembly byte code. This.NET runtime functions in the browser using WebAssembly. Additionally, WebAssembly executes in the JavaScript runtime sandbox in the web browser just like regular JavaScript code does. Here, the.NET runtime, similar to mono.wasm, is used to execute the DLLs of your Blazor applications.

Additionally, since everything is running in the JavaScript runtime, your application can make use of features like WebSockets, the File API, and the DOM. This is how the UI on the screen is created and updated by accessing the DOM. Additionally, because it runs in the JavaScript runtime, JavaScript code and application code can communicate. JavaScript can call your C# code, and C# can call JavaScript.

Introduction to Blazor

A Blazor application can be created in several different ways. Using Visual Studio, we can develop Blazor applications and gain access to the full complement of Microsoft’s development tools. Whichever version of Visual Studio we are using is irrelevant.

The lighter version of Visual Studio, Visual Studio Code, can also be used to create Blazor applications. Finally, we can use a command-line interface to create the Blazor application.

Prior to choosing the tool we prefer to use, we must first download and instal the most recent version of the SDK. Make sure ASP.NET and the Web Development Workload are enabled if we decide to use Visual Studio.

If we select Visual Studio Code, we must instal the most recent VS Code C# extension; however, if we select Common-Line, we can just run dotnet new to start a new project.

Follow these instructions:

  • Activate Visual Studio
  • Select the option to “Create a new project.”
  • Make Blazor App your project template of choice.
  • Configure the project by supplying the address and a suitable name.
  • Select either the Blazor WebAssembly App or the Blazor Server Application.
  • The Blazor Project has now been successfully created by you.

Blazor is run on the server from within an ASP.NET Core app in the server-side hosting model (Blazor Server-Side). Over a SignalR connection, UI updates, event management, and JavaScript calls are handled.

The Blazor app, its dependencies, and the.NET runtime are downloaded to the browser and run directly on the browser UI thread in the client-side model (Blazor WebAssembly). The same process is used for handling events and updating the user interface.


We have covered the definition and operation of Blazor in this article. This article should get you started on creating your own Blazor applications. In upcoming articles, let’s investigate Blazor in more detail.
