Interaction between WF and WebService
WF provides four activities: webserviceinputactivity, webserviceoutputactivity, invokewebserviceactivity, and webservicefaultactivity.The following is a brief introduction to these four activities:
1. webserviceinputactivity: enables a workflow to receive data from a Web service. When starting a web service, publish the service as a Web service method, and then call the

The boss asked me why Windows Workflow Foundation is used for BizTalk?
First, understand their Runtime Environment
WF: You can use the ConsoleProgram, Window programs, service programs, web applications, and so on to run a workflow.BTS: runs on the BizTalk Server and is mainly used to process B2B, EAI, and bam.From this we can see that WF is mainly used for applications, while BTS is mainly used for integ

After completing this chapter, you will learn:
1. Understand the concept of the state machine and how it is simulated into workflow processing
2. Create a state-based workflow
3. Application of initial (initial) and termination (terminal) condition
4. Use code to switch status
In the fourth chapter, "Introduction to activities and workflow types," I explained the types of workflows you can create with WF, where I mentioned stateful workflows. A s
After completing this chapter, you will learn:
1. Learn how to use ifelse activities to perform conditional expressions
2. Learn how to use while activities to perform loops
3. Understand how the Replicator activity simulates a for loop and how it is used.
We've seen how to execute code inside and outside the workflow, already know how to handle exceptions, pause processes, and terminate our workflows when things get out of control. But there is no doubt that the main components of any compu

In the WF environment, it is easy to cause an endless loop, because according to the forward-channing reasoning principle, a rule can trigger itself, in which case it will cause an endless loop: IF this. disCount = 10 THEN this. disCount = 10 this statement can easily cause an endless loop. In addition, when there are two or more Rules, it is easy to cause an endless loop:R1: IF this. Name! = "Headchen" THEN this. disCount = 10R2: IF this. disCount =
1. Summary
In thisArticleIn, we will mainly learn about the usage of replicator activities, and then we will pass a simulated voteProgramFamiliarize yourself with the Replicator activity.
In addition, we will try to decouple the workflow from the specific implementation method in this section.
2. Replicator
In the previous article, we learned the IF-else activity and the while activity. We learned the same idea as we learned the basic syntax of the language, we also lack an important
Objective:By now we can see that WF4 contains a designer for a. xmal file and a runtime that invokes the activity. When you create your own workflow, you are also creating an activity,Because the activity is a class that inherits System.Activities.Activity.Activities can implement business processes, and some activities implement business processes by invoking other activities, such as sayhello activities that do not write text to the console, but rather through WriteLine activities.To achieve t
Microsoft's WF is a good workflow development platform. Compared with the Open-Source Workflow implementation, its designer is not very beautiful (of course, this is also quite different from the connected designer I have seen before.) I suddenly came up with an idea last week. Can I implement a similar workflow designer on the web page ?! We all know that it is difficult to draw a line on a web page using JS (in fact, it is impossible to draw a line,

In WF, listenactivity, conditionedactivitygroup, and parallelactivity are common activities that can be executed simultaneously. Before all sub-activities are executed, a spec
In this demo we will add the If/else logic to the workflow to show the different message by customizing the condition.If the number of characters in name is odd, the first word outputs "greeting" otherwise outputs "Hello".1. Add a method to the Sayhelloincode class,2. Create a unit test in SayHelloFixture.cs to verify correctness,Running the unit test results in an error and the result is "Hello", since we have not defined the information that the workflow returns under different conditions.3.

As there were a lot of workflows used in previous projects, I was interested in learning the WF knowledge of Ms.WF definition:A workflow is defined in an activity diagram. It may be a human operation or a system process. An activity is a step in a workflow. It is embodied as an executable unit that can be reused and integrated. After the workflow is designed, it is compiled into a. Net assembly and executed by the workflow runtime and the general lang
There are two methods for workflow in WF: code mode and code mode. the xoml mode, the two can be converted to each other, which is the serialization provided in WF.And deserialization support. The following important classes in the WF framework:
The workflowmarkupserializer class is the serialization base type used in the serialization infrastructure. This type provides some basic services for serializati
I introduced the first part of wf4's new event-driven workflow design. We can summarize several key points.
1. The event mechanism of wf4 is revolutionary and different from that of WF3. WF3 is based on the externaldataexchange service. Wf4 is based on WCF. This design is much easier for developers.
2. In WF3, the so-called eventdriven activity is used, while in wf4, the activity like receive is used. In fact, this clue can be seen from the WF 3.5.

1. Use send to send messages. (Note that you cannot call methods with returned values)
2. Send and receivereply for sending and receiving responses. (Must be used in conjunction with activities)

The while and replicator do not reset the activity to the initial state each time they reuse the activity. Instead, the original activity is cloned, and each
