FileResult with MemoryStream gives empty result .. what's the problem?

Question

I\'m generating ics files ( iCalendar or RFC 2445 or however you call them) using a library that serializes the ical contents into a MemoryStream, or actually any type of stream

Answer 1

Just a guess: Do you need to Seek back to the start of the stream before you return it?

fs.Seek(0, 0);
