Using an EF Core database for the IdentityServer4 configuration data

This article shows how to implement a database store for the IdentityServer4 configurations for the Client, ApiResource and IdentityResource settings using Entity Framework Core and SQLite. This could be used, if you need to create clients, or resources dynamically for the STS, or if you need to deploy the STS to multiple instances, for example using Service Fabric. To make it scalable, you need to remove all session data, and configuration data from the STS instances and share this in a shared resource, otherwise you can run it only smoothly as a single instance.
