🧩 What is Azure AD B2C?

Imagine you're running a website where external people (like customers, vendors, or partners) need to log in — but they’re not part of your company.

Azure AD B2C (Business to Consumer) is like a secure login gate that:

  • Lets people sign in or sign up using their own email, Google, Facebook, or even Microsoft account

  • Keeps their information safe

  • Handles things like passwords, forgot password, two-step verification, etc.

So basically: Azure AD B2C = A secure sign-in system for outsiders

🌐 What is Power Pages?

Power Pages is Microsoft’s platform to create secure, public-facing websites — like:

  • A vendor portal

  • A customer support site

  • A registration or booking platform

It’s built so non-developers can design sites using a drag-and-drop editor, but it also supports pro-devs with full customization.

🔗 Why Use Azure AD B2C in Power Pages?

Because Power Pages are public websites, you often need to let external users log in.

That’s where Azure AD B2C fits in:

  • It gives you a login/signup page

  • It handles user accounts, password recovery, etc.

  • You don’t need to build this from scratch

For example:
Let’s say you're building a student portal on Power Pages.
Using Azure AD B2C, each student can sign up securely using their email or Google account.

🔐 Real-Life Analogy

  • Think of Power Pages as your new shop (a website).

  • Azure AD B2C is the security guard at the entrance.

    • He checks your identity.

    • He lets you in only if you're allowed.

    • He doesn’t care if you're from Google, Microsoft, or just using email — he can check them all.

🛠️ How It Works (High-Level Steps)

  1. Set up Azure AD B2C in Azure Portal

  2. Create a user flow (e.g., sign-up and sign-in)

  3. Configure Power Pages to connect to B2C

  4. Users visiting your Power Pages site see a "Sign in" or "Register" screen powered by B2C

🧠 Benefits

  • External users don’t need to be added to your internal company directory

  • Scalable to thousands or millions of users

  • Supports custom branding (your logo, colors)

  • Strong security and privacy controls

🧾 Example Use Cases

Use CaseAzure AD B2C Use?
Public student login portal✅ Yes
Vendor or supplier registration✅ Yes
Internal employee-only portal❌ Use Azure AD, not B2C

🚀 Final Words

If you're building a Power Pages site for people outside your organization, Azure AD B2C is your go-to login system. It's safe, customizable, and works with common identities (email, Google, Microsoft).

Automating Unique Number Generation in Dynamics 365 Using Plugins

Introduction When working with Dynamics 365, generating unique and sequential numbers for records such as invoices, quotes, or orders is a common requirement. Instead of manually assigning these numbers, we can use an Auto-Numbering Plugin to automate the process. In this blog, we’ll break down a C# plugin that implements this functionality in an easy-to-understand way. Why Do We Need Auto-Numbering? Manual numbering is prone to errors, duplication, and inefficiency. Automating this ensures: Unique numbering for each record Improved data consistency A structured format (e.g., INV-1001, INV-1002 ) How Does the Plugin Work? The plugin follows a structured approach to generate and assign unique numbers: Retrieve the Auto-Number Configuration Record Lock the record to prevent conflicts Increment the current number and update it Assign the new number to the created entity Let’s break down the code into simple steps. Understanding the Code Complete C# Code for Auto-Numbering Plugin...

In-Process vs Isolated Process Azure Functions: What’s the Difference?

 When building Azure Functions using .NET, one of the most important architectural choices you’ll face is deciding between In-Process and Isolated Process (Out-of-Process) hosting models. This decision impacts everything from startup time to dependency control and middleware capabilities. So let’s break it down. What is In-Process (InProc) Hosting? In the In-Process model: Your function code runs inside the same process as the Azure Functions runtime. It uses the same AppDomain and host environment . Benefits: Better performance (lower cold start time). Full access to features in the Microsoft.Azure.WebJobs SDK (like bindings, triggers, and logging). Easier to use existing .NET libraries and tools. Limitations: Tightly coupled to the Azure Functions runtime version. Less flexibility in middleware and custom startup configuration. Potential for dependency conflicts if runtime and your code use different versions of libraries. What is ...
