How to add custom operations to with NSwag

Question

I'm trying to add a route that isn't a Controller into my NSwag generated Open API document. I tried implementing IDocumentProcessor but the operations collection there is immutable.

How can I add an additional, non-Controller operation to the document?

Answer 1

In DocumentProcessorContext's Document property (a OpenApiDocument), there is a Paths collection where one could add the required resources/operations at that point.
