I've listened in on parts of the new Windows Forms series of webcasts, called "Soup to Nuts". They're well presented and the whole webcast deliver They've been fairly basic so far, but the sessions are organized to get more advanced as the series progresses. It seems that the .NET world was initially so focused on ASP.NET and web services, while good Winforms resources were relatively scarce. That's definitely changed, but a strong tutorial series like this is a welcome addition to the resource pool.
As an aside, the whole "webcast" experience has really improved over the last year or two. With the current MSFT webcasts, the streaming seems very stable and it's becoming less of a one-way experience -- you can respond to questions/polls from the presenter, submit questions for the presenter, send requests to speed up/slow down, and so on. Pretty cool.
