What is a Blazor?

Blazor is a new Microsoft UI framework that uses a special process to develop SPAs running in web browsers to enhance C# .NET and the WebAssembly framework. It enables a developer with HTML, CSS, and C# to build rich and interactive client-side applications.

The first interesting factor of Blazor is that we can share the code as well as libraries between the two as we write C # on the server and the client-side. Blazor is located on the top of the .net framework and has access to all the latest features of the .net platform.

Features of Blazor

Open Web Standards

Blazor is designed on top of available web standards. You don’t require a plugin in the browser to run Blazor applications, unlike Flash or Silverlight. Blazor runs on the desktop and smartphone with all modern browsers.

Sharing your code

Easily access the existing .Net standard libraries in the Blazer designs. Writing your .NET Standard library code helps you to use it on any project, including Xamarin, ASP.NET WebApi, Blazor, WPF-enabled desktop software, and more.

JavaScript is a choice

You might either have some experience using JavaScript web frameworks or that you’re familiar with the rich JavaScript library ecosystem. The excellent thing is, we have an option to use Blazor’s Javascript. Blazor enables us to access APIs and libraries for JavaScript if we need them.

Even if Blazor uses .NET and WebAssembly it doesn’t mean that it is restricted when operating with the browser. The Blazor platform makes it simple for basic activities, such as DOM function, HTTP data retrieval, and client-side routing.

Blazor also has complete JavaScript API access to the browser via JavaScript compatibility. The Blazor software can call JavaScript functions from .NET methods and JavaScript functions from .NET methods. JavaScript interop is used where an API or part for the desired function is absent from the Blazor platform or where developers wish to use the JavaScript ecosystem.

Web specifications and browser features have grown into an environment rich and stable in functionality. Standard Web technologies such as WebAssembly not only enable Blazor but also limit it to the same specifications as JavaScript. Only because Blazor is running on .NET and WebAssembly does not give it unique abilities that go beyond the security sandbox of the browser.

First-Class IDE Support

In addition to Windows, as well as Linux and macOS, all Microsoft IDEs, Visual Studio, and Visual Studio Code have a perfect Blazor development experience. Also, there are various command-line tools, allowing you to write your Blazor applications using other IDEs or editors.

Open Source

You should look up the code on GitHub if you want to learn how this functions internally. Blazor is open-source, and its main projects also have many developers.

What are Blazer Components?

A component is an individual element of the interface, page, or framework. Blazor implementations are created with adaptable, lightweight modules that can be resolved, exchanged, and shared between organizations. A component is the Blazor application’s basic component, i.e., each page is known as a Blazor section.

Component Class

A component in Blazor finally stops as a class containing both the HTML markup to offer alongside the planning justification that is required to infuse data or respond to Interface purposes.

Blazor fragments are executed using a combination of C# and HTML markup in *.cshtml records. The UI for a section is marked using HTML when the complex distribution of reasons such as circles, conditionals, articulations are included using an installed C # language framework called Razor.

We may define all the properties used for the markup in the work area, and the techniques are related to an ability to monitor. The HTML markup and C# distributing argument are changed into a component class at the stage where a Blazor program is assembled, and the name of the generated class coordinates the record name.

Component Members

In a @functions square, individuals from the segment class are characterized, and you can use more than one @functions block in a section. For example, in the @functions square, the section states, properties and fields are determined alongside periodic techniques to take care of or define other component rationales.

Render the component of code behind

In discrete documents, you will see markup and C # code justification when constructing a Blazor part. Use this order of @inherits to instruct the Blazor compiler to see the class generated from the Razor from the class displayed with this requirement.

The class defined with the @inherits directive should be purchased from the BlazorComponent class and gives all the essential usability to the component. We can transfer the C# code justification to another code-behind class from the Counter .cshtml text.

The Blazor programmer creates a class with a class name identical to the page name for all display pages, so here, a predefined base class may not have a name similar to Razor View, or it will cause an assembly time error.

Component Reusability

You can use and reuse any component in various components without much of a stretch by declaring them using HTML component grammar in Blazor. The component markup appears to be an HTML label where the tag name is the type of component. The corresponding markup offers an opportunity for an index.

Hosting models for Blazor

1. Blazer Server

Blazor Server runs the server with your razor modules and program DLLs, allowing you to take full advantage of the server’s capability. UI events that occur in the browser are transmitted to the server using SignalR using a real-time, two-way link.


  • Application loads faster
  • Complete advantage of server capabilities
  • The client should use the app in a web browser.
  • Secure


  • Requires ASP.NET Core Server
  • Needs an active connection to the server
  • Scalability

2. Blazer WebAssembly

Blazor WebAssembly or Blazor Wasm works on web assembly based Dot Net runtime directly on the webserver. Blazor WebAssembly functions closely to front-end javascript applications such as React or Angular.


  • Does not require an active server connection
  • Uses client resources and capabilities
  • We can host it on our server, cloud, Azure, CDN.


  • The first request takes more time.
  • Restricts the capabilities of the browser.
  • Not suitable for browsers that do not support WebAssembly.


Blazor is a single-page app platform that helps .NET to create immersive client-side mobile applications. Blazor utilizes free platform principles without extensions or technology transpilers. Blazor operates for all advanced web browsers, including mobile browsers. Hence, we hope the above article will let you know everything about Blazor and its components.
