At TechEd 2006 I saw the increased focus on workflows… there were many sessions covering windows workflow. Sharepoint, Biztalk and the dedicated workflow foundation sessions, all covered the different aspects. All in all it has opened many opportunities for the workflow technology in windows environments. developers now have better support for building workflow into their applications and bulding workflow applications for sharepoint, biztalk and the rest of the microsoft stack.
K2.NET, Captaris and Skelta are all going to be releasing their next versions on WF. There are few more workflow vendors need to be watched as well in this space. Nintex smart library for sharepoint from OBS and UniqueWorld’s sharepoint forms are all in bit of trouble as these entry level solutions are now in straight competition with Micorsoft’s own versions namely, MOSS workflows and Forms Server.
K2.NET has already been working on WF for some time now. Captaris are saying they need to see how MS’s final product going to be when it finally get released, but are releasing a version for WF. Skelta are supposedly working on a version embracing WF as well.
