Doc Provider In Di

Support for IOpenApiDocumentProvider in the DI container.

ASP.NET Core in .NET 10 supports IOpenApiDocumentProvider in the dependency injection (DI) container. Developers can inject IOpenApiDocumentProvider into their apps and use it to access the OpenAPI document. This approach is useful for accessing OpenAPI documents outside the context of HTTP requests, such as in background services or custom middleware.

Previously, running application startup logic without launching an HTTP server could be done by using HostFactoryResolver with a no-op IServer implementation. The new feature simplifies this process by providing a streamlined API inspired by Aspire's xref:Aspire.Hosting.Publishing.IDistributedApplicationPublisher, which is part of Aspire's framework for distributed application hosting and publishing.
