The Microsoft Patterns & Practices team held a workshop on the newly released Web Client Software Factory (WCSF) toolkit on March 12-13 in Redmond WA. The WCSF is the web client version of the Smart Client Software Factory (SCSF) that was released in early 2006. I was fortunate to be involved with Microsoft as a member of the Advisory Board that reviewed the software as it went from conception to release. Suffice it to say, Microsoft hit another home run with this handy addition to the tools available for web developers.
It brings a much needed architectural model to the back end of a web site while leveraging the best of ASP.NET and 3rd party vendors on the client side. You can learn more about the WCSF by going to the CodePlex site. There is a wealth of tutorials, programmer's guides, samples and other materials to assist you in getting started with this toolkit.
Watch the WCSF site for more notices on the March workshop (and future ones). Microsoft often releases the videos of these workshops for those who couldn't attend.
