Getting Started Tutorial. The topics contained in this section are intended to give you quick exposure to the Windows Communication Foundation (WCF) programming experience. They are designed to be completed in the order of the list at the bottom of this topic. Working through this tutorial gives you an introductory understanding of the steps required to create WCF service and client applications. A service exposes one or more endpoints, each of which exposes one or more service operations. The endpoint of a service specifies an address where the service can be found, a binding that contains the information that describes how a client must communicate with the service, and a contract that defines the functionality provided by the service to its clients.
All of the topics in this section assume you are using Visual Studio 2011 as the development environment. If you are using another development environment, ignore the Visual Studio specific instructions. Umbraco - Home. Developer's Guide/Integration/ASP.Net - FCKeditor Wiki. 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. I wasn't the first to find this limitation (it has come up a number of times on various forums), and most people seemed to have worked around this by writing custom code to read and write an XML file, but I wanted a simpler solution. The Problem First, I'll show you the three original classes I was working with:- The Solution I came up with this:-

There is one important decision to make when creating a new workflow. Will the workflow be a sequential workflow, or a state machine workflow? 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. Creating the Project Life Of A Bug.
