Description

When using a parameter of type IFormFile, the swagger "Try it out" does not give an upload button. Instead it prompts for ContentType, ContentDisposition etc.

However, it behaves as expected if a List is specified. Refer to attachments Iformfile List_Iformfile

Contributor guide

Research direction
Investigate how NSwag generates Swagger schema for IFormFile parameter compared to List<IFormFile>. Look at the code that maps .NET types to OpenAPI schema and find why IFormFile is not recognized as a file upload type.
