  • Startup.cs: Sets up essential configuration and services for your application.

5. Run the app

Press F5 or click “Debug > Start Debugging” from the Visual Studio menu to launch your new Blazor application. Visual Studio will compile the project and open a web browser window displaying your running app.

6. Customize and experiment

Now that you’ve set up a basic Blazor development environment, feel free to explore, experiment, and start building dynamic web applications. Blazor offers an extensive ecosystem of libraries, packages, and resources that can enrich your development process further.

Overview of the Blazor Project Structure

At its core, a Blazor project consists of several key components. These include:

  • Program.cs file: The entry point of your application, containing the Main method.
  • Startup.cs file: Handles the initial configuration and services registration.
  • wwwroot folder: Stores static assets like CSS, JavaScript, and images.
  • Pages folder: Houses all Razor components that act as pages/views in your application.
  • Shared folder: Contains common Razor components used throughout the application.
  • _Imports.razor file: Holds global import statements for namespaces and libraries.
  • App.razor file: Defines the primary layout and routing structure for your application.

1. Components Directory

At the heart of any Blazor application lies the Components directory, where individual components are stored. These are self-contained reusable building blocks representing parts of the user interface and can include HTML, CSS, and C# code all in one file. Components can be as simple or complex as needed, allowing you to construct your UI in a modular fashion.

2. wwwroot Folder

The wwwroot folder contains all static content for your Blazor application including CSS stylesheets, JavaScript files, fonts, and images. By placing these resources within wwwroot, they become readily accessible by your application during runtime.

3. App and Program File

Two crucial files for any Blazor project are App.razor and Program.cs. The App component (App.razor) serves as the primary entry point where all other components are nested. You’ll also configure routing for your application in this file.

On the other hand, Program.cs is where you’ll find your application’s startup logic. Tasks such as configuring services and starting the host builder are performed in this key file.

4. Shared Folder

As the name suggests, this folder holds Razor components shared across multiple pages of your web application. Components such as navigation menus or reusable content blocks can be placed in the Shared folder for easy reuse throughout your app.

5. Pages Directory

The Pages directory holds components that constitute individual pages in your application. These page components serve as the primary foundation of your app’s navigation structure.

Blazor Components

Blazor Components have been creating ripples of excitement in the web development community, providing developers with a robust and versatile framework for constructing interactive web applications. Let’s delve into the essential features of Blazor Components and discover how they can enhance your web development journey.

1. Component-based Architecture

Blazor’s component-based architecture is designed to simplify complex web applications by dividing them into smaller, manageable pieces. This approach encourages reusability and modularity, allowing developers to efficiently build and maintain scalable applications. By clearly defining each component’s responsibility, logic, and appearance, you’ll enjoy increased productivity and easier code maintenance.

2. Razor Syntax

One of the standout features of Blazor Components is Razor syntax. Razor is a markup syntax that allows developers to seamlessly mix HTML with C# code in a single file. As a result, you can quickly create dynamic components with minimal overhead while keeping the component’s structure and appearance in one place.

3. JavaScript Interoperability

JavaScript has long been the go-to language for client-side scripting in web applications. Blazor Components enable seamless interaction between your .NET code and JavaScript libraries, giving you full access to existing JavaScript ecosystems without sacrificing the advantages offered by .NET.

4. Two-way Data Binding

Blazor Components support two-way data binding, which enables an efficient synchronization between UI elements and their underlying data models. This functionality saves you time and effort when coding complex data-driven interactions by automatically updating UI components as underlying data changes.

5. Dependency Injection

Dependency injection is a design pattern that encourages separation of concerns, testability, and maintainability. Blazor Components naturally integrate dependency injection through built-in features like constructor injection and service registration within the app configuration. This component-based approach allows for a more maintainable and modular application architecture.

6. Server and Client-side Hosting Models

Blazor offers two hosting models: Blazor Server and Blazor WebAssembly. The Blazor Server model hosts components server-side, while the Blazor WebAssembly model runs components directly in the browser using WebAssembly. Both models offer unique advantages, empowering developers to choose the option that best meets their specific requirements.

Razor Syntax in Blazor

One of the game-changers behind the Blazor framework is Razor Syntax, which allows you to write HTML markup alongside C# code effortlessly. Let’s dive into the world of Razor syntax in Blazor and unlock its full potential!

Razor Syntax

Razor syntax is a powerful server-side markup language used primarily for creating dynamic web pages with a .NET backend. It is the cornerstone of both ASP.NET MVC and Blazor, seamlessly blending HTML markup with C# code to create fast and interactive web applications.

The magic of Razor lies in its ability to mix HTML markup and C# code blocks within a single file, allowing developers to add logic directly within their views. With features such as IntelliSense support and automatic HTML encoding, Razor syntax offers an effortless and enjoyable coding experience.

Exploring Razor Directives and Expressions

Razor directives are used to manage aspects of your views like imports, layouts, or dependency injection. Some common directives include:

  • `@page`: Used for routing in Blazor applications.
  • `@using`: For importing namespaces.
  • `@inject`: Enables dependency injection within a view.
  • `@layout`: Designates an external layout file.

In addition to directives, you’ll often need to use Razor expressions within your HTML markup. Expressions are written using the “@” symbol followed by C# code. This allows developers to embed variable values or call functions directly within their markup:




Using Razor Layouts and Views in Blazor

Razor layouts are used as templates, holding the common content and structure shared by various views. By defining a layout once, you can maintain consistent styling and functionality across your entire Blazor application, making it both efficient and easy to manage.

To use a Razor layout in Blazor, first create a .razor file with a name such as “MainLayout.razor” containing the HTML structure and designated areas for rendering specific views using `<RenderBody>` method. Then, simply assign this layout to individual views by adding the `@layout` directive:


@layout MainLayout


What are Reusable Razor Components?

ASP.NET Core enables developers to create custom, reusable components using the Razor syntax. These components are essentially self-contained chunks of UI and logic that can be easily plugged into any part of your application. By leveraging such components, you can create cleaner, more organized code, reduce duplication, and make future development more efficient.

Getting Started with Reusable Razor Components

1. Create a new Razor component

To begin, create a new .razor file in your project’s /Components directory (you may need to create this directory if it doesn’t already exist). Give your component a name that describes its purpose, such as “ButtonComponent.razor” or “HeaderComponent.razor”.

2. Define your component’s structure

Inside your .razor file, begin by adding the necessary HTML markup for your component and surrounding it with Razor syntax (@) tags. For example:


<button class="btn @CssClass" @onclick="OnClick">@ButtonText</button>

3. Add properties and event handlers

To make your component customizable, define public properties for any aspects that may need to be modified by the parent component. In our example BUTTON component above, we would need properties for CssClass, ButtonText, and OnClick:


    @code {

        [Parameter] public string CssClass { get; set; } = "btn-default";

        [Parameter] public string ButtonText { get; set; } = "Click me!";

        [Parameter] public EventCallback OnClick { get; set; }


4. Usage in Parent Components

To use your newly created component, simply reference it in any Razor markup file by including the component tag with its appropriate namespace, followed by any necessary attributes to set your defined properties:


<ButtonComponent CssClass="btn-primary" ButtonText="Submit" OnClick="SubmitForm"></ButtonComponent>


Benefits of Using Reusable Razor Components

  1. Code organization and maintainability: Breaking down UI elements into self-contained components promotes cleaner, more organized code.
  2. Enhanced reusability: By creating components that can be used across multiple parts of your application, you reduce the amount of code duplication and streamline development.
  3. Easier collaboration: With a standard set of modular components ready to use, team members can work more efficiently and consistently.

Blazor Server-Side vs. Blazor WebAssembly

Blazor Server-Side runs on the server where the UI updates, event handling, and JavaScript calls are managed through a real-time SignalR connection. This means that the server is responsible for processing all client-side events and rendering the updated UI back to the client via SignalR.

On the other hand, Blazor WebAssembly runs directly in the browser by downloading and executing a .NET runtime alongside your application’s DLL files. The client-side events and UI rendering occur within the browser itself with no dependency on the server for these tasks.

Pros and Cons of Blazor Server-Side


  1. Faster initial load time: Since most of the work is done on the server-side, initial load times are often quicker due to smaller file sizes sent to the browser.
  2. Utilizes server resources: This model takes advantage of server-side processing power for complex operations, potentially offloading heavy lifting from clients with lower-end hardware.
  3. Easier debugging: Debugging is more straightforward in this model as developers can use familiar tools like Visual Studio for both client and server-side code debugging.


  1. Requires constant internet connection: Since all client-side interactions rely on continuous communication with the server, a stable internet connection is necessary for a seamless user experience.
  2. Server resource demands: The server has to handle all user interactions and UI updates, leading to potentially higher server resource usage, especially for large-scale applications with numerous clients.
  3. Latency issues: Depending on the quality of the user’s internet connection and geographic location, latency can become a significant concern with Blazor Server-Side deployments.

Pros and Cons of Blazor WebAssembly


  1. Runs directly in the browser: This model allows you to build truly client-side applications that run entirely within the browser, independent of any backend server.
  2. Offline capabilities: Since the application runs within the browser, it can be built to function even when users lose their internet connection.
  3. Scalability: With most processing happening on the client-side, the backend server faces reduced pressure, making it easier to scale up your application if needed.


  1. Increased initial loading time: Due to the requirement of downloading the entire runtime along with your application’s code, Blazor WebAssembly apps tend to have larger payloads than their server-rendered counterparts, leading to slower initial load times.
  2. Limited access to browser APIs: While Blazor WebAssembly provides access to many common browser APIs through JavaScript interop, some advanced features still may require custom JavaScript code in your application if not supported directly in Blazor.
  3. Security concerns: Running client-side code in an insecure environment like a user’s browser could pose additional security risks compared to traditional server-rendered approaches.

By understanding where your application is slowing down, you can prioritize which optimization techniques to employ.

Implementing Lazy Loading and Code Splitting in Blazor

Lazy loading and code splitting are powerful techniques that significantly improve the loading times of your Blazor applications. Lazy loading involves postponing the loading of certain resources or components until they are required by the user. This enables the initial content to load faster as only essential components are fetched during the initial request.

Code splitting divides your application into smaller chunks, enabling the browser to fetch only required portions of the code during initial load or navigation actions. Implementing these techniques in Blazor often involves utilizing third-party libraries such as Blazored.Toast and Microsoft.AspNetCore.Components.WebAssembly.Services.

Optimizing Data Loading and Rendering in Blazor

Efficient data loading plays a critical role in overall application performance. To optimize data loading in Blazor applications, implement strategies such as:

  1. Use pagination to load and display data in smaller, manageable chunks.
  2. Implement on-demand data-loading techniques to fetch data only when it’s needed.
  3. Optimize API calls by limiting the number of requests or bundling multiple requests into a single one.

Additionally, optimizing component rendering can improve your application’s responsiveness. Pay attention to the following guidelines:

  1. Reduce unnecessary component re-renders by using the ‘ShouldRender’ method, which allows you to control when a component should update.
  2. Use the Virtualize component to efficiently render large lists or large amounts of data by only rendering visible elements in the viewport.

Profiling and Debugging Techniques for Blazor Performance

Proficient profiling and meticulous debugging are indispensable aspects of upholding top-notch performance in Blazor applications. Browser developer tools serve as invaluable aids, enabling you to gauge performance metrics, gain a comprehensive grasp of component lifecycles, and adeptly troubleshoot issues stemming from JavaScript interop calls and WebAssembly code.
