XmlSerializer and 'not expected' Inherited Types - The Introduction This articles describes a problem I came across with XmlSerializer, and the solution I eventually found. The ultimate solution is actually relatively simple but it took me nearly a full Thursday to figure out, so the article is more about how I got to the solution and the dead-ends on the way there. Background I wanted to be able to save a strongly-typed collection class to an XML file, but because of the way XmlSerializer works (briefly described later) and the fact that one of the properties being serialized was a base class, I couldn't do this out of the box because I wanted to store not the base class itself but the derived classes.

Windows Workflow provides these two types out of the box. A sequential workflow is a predictable workflow. A state-machine workflow is an event driven workflow. We use a sequential workflow when we can encode most of the decision-making inside the workflow itself. State machines have been around in computer science for a long time. A state represents a situation or circumstance. An event is some outside stimulus. A transition moves the state machine into a new state. Implied in the concept of a state transition is that some action will take place before or after the transition. In WF, the StateActivity represents a state in a state machine workflow.
