This might be unrelated, but your subject says AES, and your message body says RijndaelManaged. AES is based on Rijndael, but AES is not Rijndael.
Most likely you should use AesCryptoServiceProvider or AesManaged instead. The main difference is that AesCryptoServiceProvider takes more time to startup, but it's faster once it's started. So you use AesManaged for small blocks of data (a few AES blocks worth) and use AesCryptoServiceProvider for everything else. Also, supposedly AesCryptoServiceProvider isn't necessarily cross-platform compatible, but I have yet to find the platform that doesn't support it.
The Rijndael classes are mostly provided for historic, legacy, and academic purposes nowadays.
