There's always been a lot to learn but at the moment there seems to be more than ever. I was taking a look at all of the stuff coming up this year (we've just started a new financial year) and it's frightening. Here's a flavour:
Atlas, VSTS, Live, MSN bots, Gadgets, Windows Vista, .NET Framework 3.0 (including WPF, WCF, WF, CardSpace), Office 2007 server, Office 2007 client, Linq, VSTS, Orcas, VSTO...and so on. And that's just the stuff I'm reasonably close to. Oh and of course, we still have VS2005, ASP.NET and all of the other shipping technology.
One way to get a good intro to most of this stuff is to keep your eye on our "nuggets" site. A nugget is a short video - typically less than 20 minutes - that covers one specific topic. For example, want to get a quick intro to the Windows Workflow Foundation? Watch our "Windows Workflow Foundation: Hello World" nugget that runs for just 10 minutes.
We've had nuggets for some time but have recently revamped the site to make it easier to find the one you need.
Take a look at http://www.microsoft.com/uk/msdn/events/nuggets.aspx. And feel free to let me know if there are topics for which you'd like us to produce a nugget.
