## RijndaelManaged/CFB CryptoStream fails on read/write

_Submitted by a community member on 2013-01-03 17:01 UTC_

On Microsoft.NET, the attached example works properly. It encrypts correctly, then decrypts correctly, using an AES/CFB CryptoStream with no padding. On Mono, however, it fails, writing nothing to the stream.
