ASP.NET Core Web API Tutorial | Identity Framework Setup & Custom User (Full Guide)
In this video, we implement ASP.NET Core Identity in a Web API project and walk through how authentication infrastructure is set up in real-world applications.
You’ll learn how to:
. Configure ASP.NET Core Identity in a Web API
. Create a custom User entity based on IdentityUser
. Replace DbContext with IdentityDbContext
. Apply a global default schema for Identity tables
. Understand how Identity generates and manages database tables
. Explore the internal structure of Identity (Users, Roles, Claims, Tokens)
This is a critical step when building secure, scalable backend systems using ASP.NET Core + Clean Architecture.
🚀 What You’ll Gain
. Clear understanding of how Identity works under the hood
. Proper way to structure authentication in enterprise apps
. Clean DbContext integration with Identity
. Strong foundation for adding JWT/Auth later in the series
