I’m looking for visualization/simulation tools for Windows Workflow Foundation, which can show how certain data moves down the workflow and gets manipulated until the end result is reached. This is a bit similar to some IBM Rational modeling tools for Websphere.
Can someone recommend a product (preferably free, but commercial products are an option) and point me in the right direction?
Have you taken a look at this example from MSDN?
On a different option, full blown commercial product like K2 BlackPearl that is built on top of WF offer this type of capability albeit very costly.
