Blazor is a .NET framework that delivers native performance on web clients through C# runtimes and HTML wrapping. Auth0 helps you secure these applications through identity management, authentication, and authorization.

This course is a step-by-step guide to securing Blazor Server and Blazor WebAssembly applications with Auth0. You’ll start with an introduction to Blazor and its two hosting models— server-side and portable WASM binarie. You’ll then explore Auth0, which is an identity and access management (IAM) platform for connected applications. Next, you’ll set up and run a server application, integrate the Auth0 SDK, and add login functions before testing for security. You’ll finish by creating a Blazor WASM application and protecting each individual component with Auth0, including the UI and the Web API.

By the end of this course, you’ll be equipped with the proper tools to build and deploy secure web applications with the .NET’s Blazor framework and secure them with Auth0.

Securing Blazor Applications with Auth0

The weather forecast API is protected from unauthorized access attempts. Let's verify that the protection actually works.

# Check the "Fetch data" page

Before we modify the Blazor WebAssembly application to make authorized requests to the protected API, let's make sure that the API is actually protected.

In the root folder of the solution, run the application by typing the following command:

```
dotnet run --project Server
```

Now, we can go to the application’s URL, get logged in, and move to the “Fetch data” page. This is the page that calls the weather forecast API.

Learn to verify that the API is correctly protected.
