From the beginning of this article, we will first familiarize ourselves with the activities in WF. 2. Activities The core of WF is a series of activities.

Some suggestions for learning Wf

Many of my friends asked me how to learn WF. I would like to give some suggestions here. 1. Basic Knowledge: This is necessaryC #/vB syntax, generics, reflection, delegation, thread, oo ideas 2. You cannot use databases, so ADO. NET must master 3. At least master ModelingFlowchart, sequence diagram, collaboration diagram, and State Diagram 4. data structure. The design mode should at least be understood.Linked List, binary tree, responsibility cha

WF from Getting started to proficient (17th chapter): Correlation and local host communication (on)

After completing this chapter, you will learn: 1. Understand the workflow Association (correlation) and where it must be used, and why it is important 2. Use Workflow association parameters (correlation parameters) 3. Generate and use related local communication services The applications you've seen throughout this book are generally based on a single same architecture, with WF support performing tasks in the workflow instance. These are one-to-on

WF Framework Programming-Foundation Section

scheduling logic, domain model language has been very popular these years. The description of the procedure can be implemented in any one way. The problem of 1.2c# control process Take a look at the interactive process: the process of requiring the response of external messages in the process of flow. Maybe some processing will wait a few days or even weeks. If you use the C # control flow implementation, how should be implemented. The general practice is to create a new line Cheng execution

Keep learning WF (25): cancelling a container (cancellationhandleractivity)

[Stick to the top] Stick to learning WF Article Indexes The cancellationhandleractivity activity contains the cleaning logic for the canceled compound activity before all the child activities of the composite activity are completed. In WF, listenactivity, conditionedactivitygroup, and parallelactivity are common activities that can be executed simultaneously. Before all sub-activities are executed, a spec

WF (vii) (hand bag)

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.

WF study Note 1

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

Serialization and deserialization in Wf

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

WF event-driven (2)

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. 3.

Wf4 test tool WF call WCF

References: http://www.cnblogs.com/carysun/archive/2009/12/06/wf4-activitycorrelation.html The above links have more comprehensive information, which is just a key point. I have spent a few hours experimenting with this experiment. I hope you can avoid detours. 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) 3. Send key attributes and parameters

Interpreting the core principles of WF through AEC (1) Copy of activity

AEC Introduction Activityexecutioncontext is an important part of a workflow. Well, the introduction of AEC comes first and ends with a seriesArticleI will explain in detail the core principles of AEC and WF. Copy of activity While and replicator can execute its subactivities repeatedly. 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

WF4.0 Combat (19): an example of a silverlight+wcf+wf+linq combination

Overview: This demo is intended primarily to illustrate how WCF services are used in WF4, and how to invoke WCF services in Silverlight. Because the Silverlight rendering UI is used, and LINQ is used to access the database. So the name of this article is: "An example of silverlight+wcf+wf+linq combination." If you have a little knowledge of WCF like me, you know that WCF can put a lot of methods in a URI for everyone to call. So how do you put multip

WF rule designer

WF rule designer The WF engine provides three methods to start a workflow: Specifies the class for referencing workFlow. This requires referencing the workFlow DLL or placing workFlow and engine in the same project. Specify the xoml file cited for workFlow (dynamic compilation) The xoml string of the specified workFlow. I have written examples of these three methods. I have also said their advantages

Persistence in learning WF (22): Tracking rules

Insist on learning WF Article Index Because the rule is notProgramOfCodeYou cannot use the vs Debugger for debugging. If you want to debug a workflow program with rules, you can enable the tracing function of the rule engine. The following is an example. We need to create an ordered workflow project, put a policyactivity in the workflow designer, and set its rulesetreference attribute. We will create the following rule set. See the following table:

One step to learn WF series (2)-workflow and Visual Studio

1. workflow development style In WF, there are three ways to develop workflows. Here, I don't want to take the time to give an example. The workflow layout is in The XAML format. I believe that those who know about WPF and sivlerlight know this clearly. In fact, this is the same as WF. This is the so-called markup-only mode. The other extreme is code-only. We still want to think abou

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 s
