I've been going on about Patterns & Practices for a while now, so I was greatly interested to discover the day-by-day coverage of the Patterns & Practices Summit West 2005 on TheServerSide.NET.
Paul Ballard and Gregory Hoyt give a good account of each of the three days (1, 2, 3), including relevant resource links. The Enterprise Library 2.0 powerpoint is well worth a look, particularly if, as I do, you think that a community-driven best-practice library can significantly reduce development effort.
Would I want to go to an event like this? Certainly. Should there be something like this in the UK? Definitely.
Now, I just have to work out how to get to go to the Oslo event in May!
