I have been looking but so far haven't been able to find an example that deal with core 2.2 Identity and creating a custom storage provider for oracle (which current will require ADO.net and CRUD methods as opposed to EF).
Can anyone point me to a good example or a good reference?
I went through the exercise of customizing creating a custom storage provider for ASP.NET Core Identity so I could create a custom provider for IdentityServer4. I just created a minimal in memory provider. To use it with Oracle you just need to inject the Oracle data access and produce objects like the User class I have defined. The github project for my little experiment is here: https://github.com/glennsills/simpleidentity. Microsoft's documentation for a custom provider is here: https://learn.microsoft.com/en-us/aspnet/core/security/authentication/identity-custom-storage-providers?view=aspnetcore-2.2
