Implementing a custom Identity storage provider and authentication in .NET Core

Vivek Ayer 1

I'm trying to implement a custom identity storage provider that can talk to an existing SQL Server database that has bespoke user and role tables.

I have seen all the documentation I can find on implementing the various interfaces.
https://learn.microsoft.com/en-us/aspnet/core/security/authentication/identity-custom-storage-providers?view=aspnetcore-5.0

Looking first to implement the most essential ones so a user can login from a .NET core web app and the system can issue auth cookie identify the user's roles.

Is there an example project that I can look at that implements this? The User and Role stores look straight forward but I'm struggling with the custom DB Context implementation and how it can talk to my database. Also looking for more info on changes to the Startup class of my .NET Core web app and login page that will talk to my custom Identity provider.

Cheers

Hi @Vivek Ayer ,

The official document also contains the same code, you can View or download sample from GitHub. Besides, you can also refer the Role-based authorization in ASP.NET Core.

Hi @Zhi Lv - MSFT

I can't find any guidance on using the custom identity storage identifier in an .NET Core web app to see how it all ties together. Is there a working example of that?

Thanks

Is there a working example of that?

Yes. The openly published source code has everything you need. The store interfaces are located in the EntityFrameworkCore folder.
