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

We just scaffolded our basic Blazor Server application using the standard .NET project template.

# Launch the application

Let's make sure that everything works as expected so far. First, let's move to the `MyBlazorServerApp` folder and type the following command in our terminal window:

```bash
dotnet run
```

## Heads up for Mac users! 

Mac users may be affected by an issue when running an ASP.N<span>ET</span> Core application through the .NET CLI. The following window may appear repeatedly:

<center>
<img src="/api/collection/6586453712175104/5516318052188160/page/4693037397049344/image/6673985788182528?page_type=collection_lesson"
width = 400
/>
</center>

To work around the issue, open the `MyBlazorServerApp.csproj` file and set the `<UseAppHost>` flag to `false` in the `<PropertyGroup>` element.

The following example shows how the content of the `MyBlazorServerApp.csproj` file should look like:

```xml
<Project Sdk="Microsoft.NET.Sdk.Web">

  <PropertyGroup>
    <TargetFramework>net6.0</TargetFramework>
    <Nullable>enable</Nullable>
    <ImplicitUsings>enable</ImplicitUsings>
    <UseAppHost>false</UseAppHost>
  </PropertyGroup>

</Project>
```

Visual Studio users are not affected by this issue.

Check if everything works as expected by running our basic Blazor Server application.
