Secure an ASP.NET Core Blazor WebAssembly hosted app with Azure Active Directory B2C

Azure B2C not working in Blazor WASM (netstandard2.1) without the implicit grant so that is the solution

1- Create the app Microsoft Documentation

2- Copy file AuthenticationService.js from src folder to your Blazor WASM project (B2CWasm.Client) in wwwroot folder.

3- Change index.html in wwwroot folder from

<script src="_content/Microsoft.Authentication.WebAssembly.Msal/AuthenticationService.js"></script>

to

<script src="AuthenticationService.js"></script>

4- add this package to server

<PackageReference Include="Microsoft.Identity.Web" Version="1.1.0" />

5- in WeatherForecastController

...
using Microsoft.Identity.Web.Resource;
 ...

public class WeatherForecastController : ControllerBase
{
  ...
  static readonly string[] scopeRequiredByApi = new string[] { "your scop name" };
  ...
  [HttpGet]
  public IEnumerable<WeatherForecast> Get()
  {
    HttpContext.VerifyUserHasAnyAcceptedScope(scopeRequiredByApi);

    ...
  }
}
