What is the correct way to upload a file using NSwag code generator (angular 2 typescript)
I am trying to upload a file via angular 2 typescript client. The link generated in the Swagger UI works fine, but the typescript client generated doesn't work.
The controller looks like this:
[HttpGet("export")]
[SwaggerResponse((int) HttpStatusCode.OK, Type = typeof(FileContentResult))]
[ProducesResponseType(typeof(FileResult), (int) HttpStatusCode.OK)]
[Produces("text/csv")]
public virtual FileResult Export(int Id, string fileType, CsvFormat format, bool includeHeader)
{
.
.
.
FileStreamResult file = new FileStreamResult(s, "text/csv");
file.FileDownloadName = ts.Name + "." + fileType;
return file;
}
Swagger interface: 
The generated typescript client looks like this. As you can see, responseText is set but never returned. What am I missing?
protected processRestTimeSeriesExportGet(response: Response): Observable<void> {
const status = response.status;
if (status === 200) {
const responseText = response.text();
return Observable.of<void>(<any>null);
} else if (status !== 200 && status !== 204) {
const responseText = response.text();
return throwException("An unexpected server error occurred.", status, responseText);
}
return Observable.of<void>(<any>null);
}

Found the answer to this problem:
On startup add:
services.AddSwaggerGen(options =>
{
options.MapType<FileContentResult>(() => new Schema
{
Type = "file",
});
}
And for your controller:
[HttpPost()]
[SwaggerResponse(200, typeof(FileContentResult))]
[ProducesResponseType(typeof(FileContentResult), 200)]
public async Task<FileResult> MyMethod(Viewmodel vm)
{
Late answer, but for people who have the same problem ...
