Swagger doc stopped generating using swashbuckle

I have been developing a WebApi2 REST API with swagger docs (using swashbuckle) for a while now however in my local sandbox version I cannot get to the SwaggerUI, nor the swagger xml via a GET request. I have compared swagger setup between my code versions and there has not been any code changes in this area. I have uninstalled swashbuckle and IISExpress without any effect. I am running out of ideas and I would appreciate some advice on next steps to try and debug the swagger generation / or find out if there is any logging I can switch on the help diagnose further.

Apologies for posting such a general problem, but I am at a loss after looking at this for about 5 hours now.

Thanks

Mark

What is url of your SwaggerUI? What does happen when you navigate to that url? Do you get an error message? Did you inspect the HTTP messages using a tool like Fiddler? - venerik
404 both for this and also going direct for the v1 doc - I will leave this open for a bit in case it helps collate info for others, but I ended up reverting and applying my changes again - Mark Ruse
Did you ever figure this out? - bsayegh
Unfortunately not - reverting to a working version and applying my changes was the only solution I could find. Do you have the same issue? - Mark Ruse

I know it's an old question, but something similar happened to me and might happen to somebody else. The csproj has the "Build > XML doc file" config set. Swagger stopped generating the right docs because this option got unchecked, I might have disabled it accidentally. Checking it again and setting the value used in Swashbuckle config did the trick!
