Introducing Windows Workflow Foundation

Bayer White · Apress eBooks · 2013

Before jumping into how WF is used, it is important to understand the capabilities that it provides. This chapter gives a brief introduction to WF and how it has changed over the years. Important components of WF will be introduced, such as some of the out-of-box activities that model coding constructs and how activities use the workflow designer for workflow orchestration or arranging activities within a workflow for modeling business logic. Next,WF data modeling will be covered; this is how workflows receive, store, and return data. Each of the WF components covered in this chapter will contribute to building a foundation of how WFworks; ifyou're already familiar with WF, this chapter will serve as a review of important concepts. KeywordsBusiness ProcessExternal EventParallel ActivityChild ActivityVisual StudioThese keywords were added by machine and not by the authors. This process is experimental and the keywords may be updated as the learning algorithm improves.

Introducing Windows Workflow Foundation

Apress eBooks · 2008

.NET 3.0 shipped with a particular programming framework named Windows Workflow Foundation (WF). This API allows you to model, configure, monitor, and execute the workflows (which, for the time being, can simply be regarded as a collection of related tasks) used internally by a given application. The out-of-the-box solution provided by WF is a huge benefit when building software, as we are no longer required to manually develop complex infrastructure to support workflow-enabled applications.

Dynamic Workflow Instrumentation for Windows Workflow Foundation

Bart J.F. De Smet, Kristof Steurbaut, Sofie Van Hoecke et al. · 2007

As the complexity of business processes grows, the shift towards workflow-based programming becomes more attractive. The typical long-running characteristic of workflows imposes new challenges such as dynamic adaptation of running workflow instances. Windows Workflow Foundation (in short WF) was released by Microsoft as their solution for workflow-driven application development. Although WF contains features that allow dynamic workflow adaptation, the framework lacks an instrumentation framework to make such adaptations more manageable. Therefore, we built an instrumentation framework that provides more flexibility for applying workflow adaptation batches to workflow instances, both at creation time and during an instance's lifecycle. In this paper we present this workflow instrumentation framework and performance implications caused by dynamic workflow adaptation are detailed.

Introducing Windows Workflow Foundation 4.0

Andrew Troelsen · Apress eBooks · 2010

A few years back, Microsoft shipped an API named Windows Workflow Foundation (WF) with the release of NET 3.0. This API allowed you to model, configure, monitor, and execute the workflows (which are used to model a business process) used internally by a given .NET program. The out-of-the-box functionality provided by the first release of WF was very a welcomed step in the right direction, as we were no longer required to manually develop complex infrastructure to support workflow-enabled applications.

.NET 3.0: Windows Workflow Foundation

Apress eBooks · 2008

Workflow is what happens when an item is moved through various stages or people through a fixed business process. This process contains a number of steps or activities that can be acted on by machines, people, or a combination of both, and can involve various rules. For example, when you first join a new company, a set of business processes gets invoked. You need to be added to payroll, you need an office to be assigned, equipment and furniture need to be set up, and so on. Behind the scenes, a business process kicks in for the new hire. Or, when a company sells something, it typically begins with receipt of a purchase order. The purchase order has to be entered into the business system. This sets up a requisition for the product from stock. If not enough of the product is available, more needs to be ordered. When enough of the product is available, it is moved to shipping. Shipping boxes them up and sends them to the customer. Billing then generates an invoice to send to the customer. Billing also tracks payment, and if the customer pays, the order is flagged as such. If they don’t pay by the time of the terms of the invoice, a new process for collections is kicked in.

Využití BPMN ve Windows Workflow Foundation

Bielik, Martin · DSpace VŠB-TUO (VŠB-TUO) · 2018

Modelovanie business workflow je v dnešnej dobe neodmysliteľnou súčasťou každého podniku.\nBusiness workflow sa využívajú pre znázornenie chodu podniku, či priamo spúšťajú chod podniku.\nAktuálne sú dostupné dve rozsiahle notácie vykonávajúce tvorbu workflow - BPMN a WF.\nDobrým nápadom by teda bolo preskúmať možnosti konverzií medzi nimi. Tým sa zaoberá táto\ndiplomová práca. Začiatok práce bude zameraný na technológie a ich možnosti. Ďalej predostriem\npožiadavky a problematiku prevodu. Praktická časť práce je zameraná na postup riešenia,\nako aj na hlavný algoritmus prevodu. Diplomová práca ďalej hovorí o nástrojoch, ktoré majú\npodobnú funkcionalitu a kde porovnám svoje výsledky s ich výsledkami. Spomenuté sú taktiež\nmožné rozšírenia nástroja, ako aj obtiažnosť týchto rozšírení. V závere je zhodnotený prínos\npráce a splniteľnosť podmienok.

Essential Windows Workflow Foundation (Microsoft .NET Development Series)

Dharma Shukla, Bob Schmidt · 2006

“Something big is about to happen....”i¾–From the Foreword by Don Box, Architect, Microsoft Corporationi¾ “If I were writing a Workflow book, this is what I would have written. The material is very well presented with code examples and explanations. Also, I love how the authors discuss the underlying architecture, enabling me to get a really deep understanding of the technology to efficiently design and build my own projects.”i¾–Jeffrey Richter (http://Wintellect.com)“Explicit support for workflows in a lightweight framework is a major contribution. Many tough problems traditionally faced by application authors, such as state management in the presence of long-running activities (think weeks or months!), can be addressed systematically by adoptinga workflow approach. Dharma Shukla and Bob Schmidt present the workflow technology under and made accessible by the new workflow foundation in the .NET 3.0 framework, and they do so in an approachable and yet authoritative way that is truly enjoyable.”i¾–Clemens Szyperski, software architect, Microsoft Corporationi¾ “The Windows Workflow technology combines declarative programming and state machines in a very rich and powerful way, one that is bound to have a profound influence on the way we program in the coming years. In the style of the classic Essential COM by Don Box, Dharma and Bob have done a great job making this technology accessible to any developer already versed in C#, VB, and the .NET Framework, and who wants to achieve declarative enlightenment. Don't miss out.”i¾–Joe Duffy, program manager, Common Language Runtime (CLR) team, Microsoft Corporationi¾ “I think WF should and will be used as the main application model for web service applications. Developers working on web services will want to learn about this technology from this book; it comes straight from the source and explains the technology well and in depth.”i¾–Krzysztof Cwalina, program manager, Microsoft Corporationi¾ “This book provides an enlightening exploration of Windows Workflow Foundation for both the novice and the veteran alike.”i¾–Nate Talbert, software design engineer, Microsoft CorporationWindows Workflow Foundation (WF) is a groundbreaking approach to writing and executing programs. WF programs are assembled out of resumable program statements called activities, which provide encapsulation of both domainspecific logic and control flow patterns reflective of real-world processes.In Essential Windows Workflow Foundation, two WF lead architectsi¾–Dharma Shukla and Bob Schmidti¾–offer an under-the-hood look at the technology, explaining the why and not just the how of WF's key concepts and architecture. Serious WF developers seeking details about how to effectively utilize and extend the framework by writing activities will find cogent explanations and answers here. With simple and illustrative examples, the authors demonstrate exactly how to leverage WF's extensible programming model to craft domain-specific programs. Drawing on their unique vantage point in designing and developing WF, Shukla and Schmidt deliver authoritative coverage of The core concepts and ideas that form the heart of WF's programming model The execution model for activities, with details of the activity automaton, bookmarking, scheduling, and the threading model of the WF runtime Advanced execution concepts, including activity execution contexts, transactions, persistence points, passivation, fault handling, cancellation, compensation, and synchronization Hosting the WF runtime in applications The activity component model, with details of validation, compilation, serialization, and visualization Databinding, XAML, dependency properties, and WF program metadata Declarative conditions and rules, activity designers, and designer hosting Custom control flow patterns ranging from simple sequencing and iteration to more complex graphs and state machines Dynamic editing of running WF program instancesEssential Windows Workflow Foundation is the definitive resource for developers seeking an in-depth understanding of this novel technology.Dharma Shukla is an architect at Microsoft working on next-generation programming models. A founding member of the Windows Workflow Foundation (WF) team, Dharma played a key role in defining the architecture of WF. Bob Schmidt is a senior program manager at Microsoft working on next-generation programming models. Since 2003, his primary focus has been on the design of WF. Both authors have been involved with the WF project since its inception, and have been responsible for specifying, designing, and developing large portions of the technology.Contents About the Authors xiii Foreword xv Preface xvii Acknowledgments xxi 1 Deconstructing WF 1 2 WF Programs 33 3 Activity Execution 53 4 Advanced Activity Execution 111 5 Applications 179 6 Transactions 241 7 Advanced Authoring 259 8 Miscellanea 325 Appendix A Activity Automaton 395 Appendix B Control Flow Patterns 397 Index 435

Building Human-Oriented Workflows Using Windows Workflow Foundation

Apress eBooks · 2007

Every day, information workers follow work processes to get their jobs done. Some of those work processes will be quite formal, others very informal. Some of those processes will involve one or more people within the same organization; still others will involve multiple people working for different companies. These work processes have one thing in common: they are all examples of human-oriented workflows. A subset of this wide range of workflows falls in the solution domain of SharePoint 2007. SharePoint 2007 allows information workers and developers to create and use document-centric workflows.KeywordsVisual StudioDialog WindowDesign ViewDocument LibraryAsynchronous TaskThese keywords were added by machine and not by the authors.

Microsoft's Windows Workflow Foundation and

Sharanya Eswaran, David Del Vecchio, Glenn Wasson et al. · 2008

Numerous Grid workflow engines exist, each generally specialized for a single application domain such as protein folding. Although the underlying purpose and functionality of the Grid workflow engines are similar, and they make use of a common set of Grid protocols, the implementations vary vastly, making interoperation among them nearly impossible. On the other hand, the concept of workflows of Web services is very popular in the enterprise domain and many engines exist for business workflows. These mostly revolve around the Business Process Execution Language (BPEL), an emerging standard for Web services workflow description. We study three different business workflow engines- Microsoft's BizTalk Server,
