Can Azure AD B2C coexist with OWIN Identity?

Question

The current app I'm working on uses Microsoft.AspNet.Identity.Owin with SignInManager and UserManager.
It also uses Microsoft.AspNet.Identity to get the currently signed in user. The users are stored in the database using the dbo.AspNetUsers. Also roles and rights are defined in the database.

Is it possible to link the 2 so that when you're logged in with Azure AD B2C, you will also be logged in on the current Identity?

Hi @Prateek Rathore ,

Yes, you can use OWIN in B2C. We have the new Microsoft.Identity.Web v2.0-preview integration guide that goes over some of the considerations on the B2C side. https://github.com/AzureAD/microsoft-identity-web/wiki/v2.0#owin

We also have the guide, B2C with OpenID Connect.

I believe the issue with your implementation is that the data in dbo.AspNetUser needs to be migrated to the tables used by the new ASP.NET Core 2.0 Identity schema, as discussed here. https://learn.microsoft.com/en-us/aspnet/core/migration/proper-to-2x/membership-to-core-identity?view=aspnetcore-6.0

Let me know if this helps and if you have further questions! I've added the dotnet tag to this thread too since that team supports OWIN issues.
