Hi @commonsensesoftware

This branch builds using a locally-built OpenApi assembly from the changes in dotnet/aspnetcore#66692.

The PR above makes three important changes:

• Allows AddOpenApi to be called with null document name - which means "register only core services"
• Adds a public IAdditionalOpenApiDocumentNameProvider interface that you can register to provide the document names.
• Uses AnyKey for most service registration. This is what gives the flexibility of not needing the document names early when building the host, and allows keyed service retrieval to work for any requested document. At that time, we can then validate the document names as the information will be available then.

Can you please double check that everything works correctly with those changes?

Once you confirm that everything works, I'll create a proposal in aspnetcore repo that replaces dotnet/aspnetcore#66408 and review it with the team.

I might as well tweak some stuff in the current shape I have. For example, I would like the proposed public interface to be not only responsible for the "additional" document names, but basically provides all the document names. That means that we can remove GetDocumentNames from IDocumentProvider. This will also clean up part of our code here.

Ping @commonsensesoftware.

It would be good if you can test this soon so we have enough time to bring it in for .NET 11.
