Course Description

Azure has lots to offer but when it comes to securing application one thing that stands out is Azure Active Directory B2C. It is one of the buzz words with azure that is often misunderstood or misconfigured. In this course we will learn the basics of Azure Active Directory B2C (AD B2C)

There are many courses online which will teach you basics of Azure and what Azure AD B2C is, but there are very few to none that comes close to actually implementing and consuming Azure AD B2C. That will be the main focus of this course.

When you’re finished with this course, you’ll have the skills and knowledge of Azure AD B2C needed to allow anybody to sign-in to your applications and then manage those users.

Throughout the course we will

  • Create B2C tenant and register applications

  • Consume Azure B2C in a .NET MVC application

  • User flows in azure B2C

  • Add B2C authentication using AddMicrosoftIdentityWebApp

  • Custom properties in user flows

  • Customize consuming B2C using OpenIdConnect in .NET

  • Secure API using azure B2C

  • Single Sign-On

  • Deploying applications to Azure

  • Common errors and edge cases

This course will take you through the basics and give you a solid foundation in Azure Active Directory B2C to implement authentication in your .NET Applications.

I am a passionate and creative software engineer with a strong focus on simplicity and thorough details. I have been programming since high school and I have been involved with multiple web and desktop using .net.

I have a master's of science degree in computer science and a Bachelor of Computer Engineering. I also have many years of experience with .NET C# and .NET MVC. I enjoy teaching along with my full-time job.

For me, the most important part about writing and teaching code is to eliminate the hardships of every student out there who is willing to learn but cannot find adequate resource which is easy to understand. Coding is a way to be creative and have fun!

Good Course ...Brugen is a very good tutor. I’ve already attended another course from him, Azure for .NET Developers, which was an awesome course, and this one is as well.

By Hemant Soni on 12/4/2023

Gr8 content, enjoyed session, one thing please add in like if we are using only AzureAd and don't want to use B2c then how we can implement user registration to store user information in local database as well. Thanks.

By Zdrave Micev on 11/5/2023

Too much workaround! Maybe this course is to be updated. Also this course seems to be incomplete because there's no implementation for the roles in the API. Bhrugen is very good to explain the things, but for me there's missing pieces. Theres some optimizations to do. Also theres no Clean Architecture Design pattern.

By Gabriel Mamani on 3/12/2023

The course and all the materials are both comprehensive and informative. I greatly enjoyed the course, in terms of both the instruction and resources that were provided.

Excellent course! Would like to see this using Blazor rather than MVC and to see it extended to access Microsoft Graph API, such as today's calendar for a selected user.

The Author could first be running the first scenario to succeed then, fall back on failing scenarios then explaining the raison for failures, I am having memory overheads trying to keep in mind the reason of all the fail attempts.

By Ricardo Rangel Ramírez on 2/21/2022

Excellent course that teaches you not only the basics of Active directory but also B2C. In addition to this, we can also see how to consume APIs using this technology. I highly recommend this course to all .Net developers who want to learn how to use Active to learn how to use Active Directory.

By Sachin Kumar on 9/7/2021

this caurse is not updated, when you will start learning through this course you will see there is no support in azure for that element (azure Active directory), MS teams moves to Microsoft entra Id. more important the instructor does,nt care about your question and may not reply.

By Kiet Pham on 8/24/2021

This is an amazing course. The instructor is very accurate in what he says and shows everything in code, not just theory. very good and clean code, teaches you bets practices and of course you learn exactly what the course says. Thank you!!!!!!

By Badr BinHomeed on 8/24/2021
