.NET Core 2.0 BasePath Error

OK, in 1.X you could just add a base path to your applicationUrl in your launchOptions while running from command line, now it only works when using IIS.

in my launchSettings, changing my CLI profile from using

"applicationUrl": "http://localhost:5000/swagger"

to

"applicationUrl": "http://localhost:5000"

did the trick.

As @TanguyB said, you should change applicationUrl But then you may set

"launchUrl": "http://localhost:5000/swagger"

to run your application on Swagger page
