• Basic asynchronous work in Windows Workflow Foundation 4
  
  The whole asynchronous execution model in WF 4 has changed quite a bit from WF 3. It does nothing useful, it’s only task is to show how to get started with asynchronous work in WF 4. The important parts here are: CodeActivityContext.SetupAsyncOperationBlock() This basically tells the runtime that the activity is going to do something asynchronously and that the runtime should not continue with the next activity when the Execute() is finished. If you need the sort of asynchronous work where you might be waiting for day’s on an end user this is not the way to go.

• More asynchronous work in Windows Workflow Foundation 4
  
  In my previous post I showed how to use an AsyncOperationBlock to do some basic asynchronous work in WF 4. As I mentioned this was for relatively short lived asynchronous operations as the workflow could not be persisted and unloaded while this asynchronous work was executing. So how about real long running work, the kind you run into with real business application like waiting for an invoice to be paid? With these king of jobs an AsyncOperationBlock will not work because you don’t want to keep the workflow in memory all the time. So what do we need to use here? Enjoy!

• The new Windows Workflow Foundation 4 runtime
  
  In both WF3 and WF4 running the workflow is done asynchronously so we need to wait, in both cases done using a Console.ReadLine(). With WF3 there was a central workflow runtime environment called the WorkflowRuntime and used to manage the lifetime of workflow instances. In WF4 this central class no longer exists and we manage individual workflows. To compare the two, this is what a minimal console application looks like in WF3. It basically runs a workflow and prints a message when done: static void Main( string [] args). {. Console.WriteLine( "The workflow has completed."

• WCF Duplex Messaging
  
  There are many ways that messages can be exchanged between two parties in a service based system: the client can send messages to the server and never get any back; the client can send a message and wait for a response; the client and service can send eachother messages without any pre-defined pattern; the client can send the service a message but not wait synchronously for a response and then then service can send a message back asynchronously; and there are many others. This is because your client is probably a Rich Client GUI based application (Windows Forms or WPF).

• WPF Data Providers
  
  An interesting facet of this provider is that it performs it's work asynchronously -- you can see this behavior when you load very large XML files. lt; Window Title = " AsyncDataBind " Height = " 300 " Width = " 300 ". One of the nifty new features of the WPF platform is the pluggable data providers. It ships with two out of the box: ObjectDataProvider: allows you to execute binding expressions against an object and it's methods. XmlDataProvider: loads an XML data source and makes it available as a binding source. State, Age, Income. xmlns = " [link] ". Until then.

• NativeActivity – A Tricky Beast
  
  I’m writing Essential Windows Workflow Foundation 4.0 This means I want to do fancy things like have child activities or perform long running asynchronous work. with Maurice for DevelopMentor. One of the things that I think is less than obvious is the behavior of NativeActivity. What is NativeActivity I hear you ask? Well there are a number of models for building custom activities in WF4. Most “business” type custom activities will be built using a declarative model in XAML by assembling building blocks graphically. However, what if you are missing a building block? 13: {. 27: {.
