Got stuck into LINQ to XML the other week and I thought wouldn't it be great if this could be strongly typed somehow. Of course the MS XML Team were WAY ahead of me. You can find the article at their blog here.
It's only in preview Alpha 0.2 Refresh at this stage (here) so I'm a little hesitatent to install on my regular machine. What the heck, if you're not living on the edge, you're taking up too much room. Right?
Scott Hanselman also has some interesting thoughts on LINQ to Everything.
