Windows Workflow Foundation 4.0 / 4.5

מק"ט: #41972 | משך קורס: 24 שעות אק'

Windows Workflow Foundation is Microsoft's .NET implementation of a Workflow authoring and hosting environment. With WF 4.5 the developer can easily author his or her workflows using the VS2010 built-in WF designer, host them in multiple application environments using the provided runtime engine and even expose them as services for the outside world to consume. Oh, and it's totally free...
In this 3-day course we will learn all of the basics of WF 4.5 from simple activities to custom defined native activities, and from a simple "Hello World" workflow up to an AppFabric hosted Workflow Service.
