Access ConfigurationDbContext outside startup

Question

How can we access the same instance of ConfigurationDbContext outside the startup class after we configure it in the Startup.cs ? I want to create a repository with ConfigurationDbContext and want to use the same instance of ConfigurationDbContext as configured in startup.

As you could see in IdentityServer4.EntityFramework source code, ConfigurationDbContext is registered in built-in DI as Scoped (which actually means "per web request"). Moreover, it's also registered as implementation of IConfigurationDbContext interface.

To get access to ConfigurationDbContext instance, just inject it in your services via DI:

public MyService(IConfigurationDbContext context)
{
}

public HomeController(ConfigurationDbContext context)
{
}
