I'm attempting to build an ASP.NET Core API with authentication/authorization handled by IdentityServer4. IdentityServer4 is being backed by both Identity and Entity Framework Core. My goal is a fairly standard and familiar set up, where users can login into a API developer portal where they can add "applications" (clients) and have a client id and client secret generated that they can then use to access the API, similar to how Facebook, Google, etc. handle API access.
My mental block is coming with the way IdentityServer handles Entity Framework integration. Their entities are attached to two different contexts, ConfigurationDbContext and PersistedGrantDbContext. I'm at a loss for a good way to associate one or more Client entities from IdentityServer4.EntityFramework with one or more ApplicationUser entities from my Identity context.
This seems like it would be a fairly common usage scenario, but the documentation is strangely silent on it. I've also been unable to find anything online after various and sundry searches. I'm hoping someone else has needed this same setup and can give me some advice on how to proceed.
