Think of: WF and SharePoint

Previously, I saw in Asp.net 3.5 building a web portal site using WF to build an architecture business process. I felt very cool and didn't care too much about it. During this time, I have been planning to use WF to build a workflow solution, suddenly I thought: If workflow is used as a part of Sharepoint to replace events, is it a good solution, but I found that there are too many problems to solve.

The sharepont workflow is actually not the same as the WF. in the traditional sense, the work of the workflow is no less than the number of tasks for custom development of an available workflow.

However, if we used WF to build the architecture in the early stage, it would be another thing. It seems that there are great application prospects. I 'd like to find a start point to try.
