Well this is off topic in my opinion, but I think Silverlight simply has worse designer tools than Flash. There isn't anything intrinsically bad about .NET, it just so happens that the tools are nothing a designer would ever put up with. I encourage you to try Blend...defining a few animations is magnitudes more complicated than just drag and dropping stuff into keyframes and then pressing play.
