Convert the ClaimsPrincipal object returned by Azure B2C into this adapter to read the user claims

Introduction

For applications leveraging Azure B2C which want a clean way to read the claims you have passed in your workflow back to the application.

This small lightweight library unpicks all the claims in the ClaimsPrincipal.

Usage

ClaimProperties userClaims = _tokenManager.ConvertClaims(User.Identities.FirstOrDefault().Claims);

string name = userClaims.name;

string jobTitle = userClaims.jobTitle;

Setup

1. Your application must already be using Azure B2C. You should see something similar startup.cs.

    services.AddAuthentication(AzureADB2CDefaults.AuthenticationScheme)
                .AddAzureADB2C(options => Configuration.Bind(CurrentEnvironment.IsDevelopment() ? "AzureAdB2CDev" : "AzureAdB2C", options));

2. Add a project reference to the Managers class libary from within this repo.

3. Register the dependency in your startup.cs.

public void ConfigureServices(IServiceCollection services)
      {
          //Add Token Manager to dependency injection 
          services.Add(new ServiceDescriptor(typeof(ITokenManager), new TokenManager()));
      }

4. Finally Inject it into your controller

        ITokenManager _tokenManager;

        public HomeController(ITokenManager tokenManager)
        {
            _tokenManager = tokenManager;
        }

        public IActionResult Index()
        {
            ClaimProperties userClaims = _tokenManager.ConvertClaims(User.Identities.FirstOrDefault().Claims);

            string name = userClaims.name;

            string jobTitle = userClaims.jobTitle;

            return View();
        }
