Blazor Webassembly Custom Login Page

Blazor WebAssembly is a modern web framework that allows developers to build interactive web applications using C# instead of JavaScript. One of the key features of Blazor WebAssembly is the ability to create a custom login page. In this article, I will walk you through the process of creating a personalized login page in Blazor WebAssembly and share my own experience and insights along the way.

Getting Started with Blazor WebAssembly

Before we dive into creating a custom login page, let’s quickly go over the basics of Blazor WebAssembly. Blazor WebAssembly uses WebAssembly to run .NET code directly in the browser, making it possible to build rich, interactive web applications without relying on JavaScript. To get started, you’ll need to have the .NET Core SDK installed on your machine.

Once you have the .NET Core SDK installed, you can create a new Blazor WebAssembly project using the following command in your terminal or command prompt:

dotnet new blazorwasm -o MyCustomLoginApp

This command will create a new Blazor WebAssembly project named “MyCustomLoginApp” in the specified directory. Navigate to the project directory to begin working with your new Blazor WebAssembly application.

Creating a Custom Login Page

Now that we have our Blazor WebAssembly project set up, let’s move on to creating a custom login page. In Blazor WebAssembly, the default login page is a simple form with text inputs for the username and password. However, we can customize this page to match our application’s branding and design.

To create a custom login page, we first need to create a new component that will serve as our login page. In the “Pages” folder of your Blazor WebAssembly project, create a new file called “Login.razor” and add the following code:

@page "/login"


In this example, we have defined a new route for our login page using the @page directive. We also added a heading and a placeholder for our login form code. Feel free to customize the content according to your own requirements.

Next, we need to update the “App.razor” file to include a navigation link to our custom login page. Open the “App.razor” file and modify the code as follows:

Sorry, there's nothing at this address.


Here, we have added a new NavLink component that will navigate to our custom login page when clicked. This will ensure that users have a way to access the login functionality from anywhere in the application.

Now that we have our custom login page set up, we can start designing the login form to fit our needs. You can add form fields, validation logic, and any other customizations you require to enhance the user experience.


In this article, we explored how to create a custom login page in Blazor WebAssembly. We learned the basics of Blazor WebAssembly, created a new Blazor WebAssembly project, and customized the login page to match our application’s branding and design. By taking advantage of Blazor WebAssembly’s flexibility, we can create login pages that truly reflect the unique identity of our applications.
