It's about adding a phase 1.5 to the tutorial to show how to sign-in users with social identities or local identities with Azure AD B2C

Repro-ing the issue

Go to 1-WebApp-OIDC/1-5-B2C

Expected behavior
A sample is available to explain how to sign-in users to the Web App using Azure AD B2C.

Actual behavior
The directory is empty

Possible Solution

It would be good to:

• clone the 1-WebApp-OIDC/1-1-MyOrg sample
• then re-incorporate the B2C specific elements from the following sample https://github.com/Azure-Samples/active-directory-b2c-dotnetcore-webapp. (See below)

Note that that sample is a bit old (ASP.NET Core 2.1), and since then, classes such as Azure AD B2C Options, etc ... are available part of ASP.NET Core. (https://github.com/aspnet/AspNetCore/tree/master/src/Azure/AzureAD/Authentication.AzureADB2C.UI/src)

It might be good to:

• leverage Microsoft.Identity.Web as much as possible (hence the idea of cloning 1-WebApp-OIDC/1-1-MyOrg](https://github.com/Azure-Samples/active-directory-aspnetcore-webapp-openidconnect-v2/tree/master/1-WebApp-OIDC/1-1-MyOrg)
• In the library, add a StartupB2Helper.cs file containing a StartupB2CHelpers class similar to StartupHelpers providing the method public static IServiceCollection AddAzureAdB2CAuthentication(this IServiceCollection services, IConfiguration configuration) which would:

services.AddAuthentication(AzureADDefaults.AuthenticationScheme)
                ..AddAzureAdB2C(options => Configuration.Bind("Authentication:AzureAdB2C", options))

Maybe have a new method for the OpenIdConnect code which is the same for AzureAD B2C and Azure AD v2.0 (a lot)

Additional context/ Error codes / Screenshots

Good ideas in the B2C sample should be brought back as well in the AAD tutorial (for instance logging ?)

@TiagoBrenck
assigning this issue to you. Ping me if this is not clear. The work (given that most of the code is now in ASP.NET core directly) should be minimal.
