This project came to being because I began to use Mono at work. I decided to take my existing game (52 Pickup) and make sure it works in Mono. There was some problem getting the animation to work properly in Mono (or in .net, depending on your perspective). After some tinkering I got it to work.
Soon after that I did a search for a sound library that worked easily between .net and Mono and found none. Knowing the trouble I had with simple animation I decided to break off the animation classes from the game and distribute them under the LGPL.
I see the advantages of the library is that it only depends on the .net framework - no openGL or other libraries are required. And I have made efforts to ensure it works running on Mono in Windows, Mono on Linux and on Windows .net. This means that if you want to use the library, just drop it into your project and code against it. It should then work anywhere.
