Maybe if it helps, here is a complete open source AES/RijndaelEngine in C#, which handles 128/192/256 Keys, based on Bouncy Castles:

By the way, Bouncy Castle has a complete suite of C# crypto components: http://www.bouncycastle.org/csharp/ and it also has a nice license: http://www.bouncycastle.org/csharp/licence.html
