Entra.EventHandlers.Abstractions

Lightweight, dependency‑free public abstractions for building
Microsoft Entra External ID and Workforce Authentication Event Handlers.

This package is MIT‑licensed and safe to use in all scenarios, including commercial applications.

✨ Features

✔ Strongly‑Typed Protocol Models

Includes complete request/response models for:

  • AttributeCollectionStart
  • AttributeCollectionSubmit
  • EmailOtpSend
  • PasswordSubmit
  • TokenIssuanceStart
  • VerifiedIdClaimValidation

Each event includes:

  • Request model
  • Response model
  • Action definitions
  • Payload types
  • Handler interface

✔ Framework‑Agnostic

The abstractions package contains no hosting logic and no dependencies.

Use it freely with:

  • ASP.NET Core
  • Azure Functions
  • Custom hosts
  • Unit tests
  • Any DI container
