Mike Griffin at EntitySpaces has posted Part 2 of my EntitySpaces + Silverlight tutorial.
http://www.entityspaces.net/blog/2008/05/24/EntitySpaces+And+Silverlight+Demo+Part+2.aspx
It barely touches on the purest basics of filtering and updating data with Silverlight, EntitySpaces, WCF, and LINQ.
Not a whole lot to it, there's SO MUCH more that ES (particularly), Silverlight 2, WCF, and LINQ have to offer, but it's good quick-and-dirty tutorial knowledge nonetheless.
And no, I haven't been slaving away at this second part of the tutorial all this time. I finished it a long while back, its posting was delayed for various reasons not related to the demo/tutorial. I might still yet get into some advanced tutorials but we'll see.
