I am trying to workthrough "Microsoft Workflow Foundation Tutorials".


I am creating workflow in VS 2008 by adding simple class with .vb extension and getting this error in designer view.

"The service 'System.Workflow.ComponentModel.Design.IIdentifierCreationService' must be installed for this operation to succeed. Ensure that this service is available."

System.ComponentModel.DescriptionAttribute not showing up in REST service

I am trying to set the description for a REST WCF service, but it doesn't seem to be working. Code is: [AspNetCompatibilityRequirements(RequirementsMode=AspNetCompatibilityRequirementsMode.Allowed)]     [ServiceBehavior(InstanceContextMode=InstanceContextMode.PerCall)]     [WebDispatchFormatterConfiguration("application/xml")]     [WebDispatchFormatterMimeType(typeof(WcfRestContrib.ServiceModel.Dispatcher.Formatters.PoxDataContract), "application/xml", "text/xml")]     [WebDispatchFormatterMimeType(typeof(WcfRestContrib.ServiceModel.Dispatcher.Formatters.DataContractJson), "application/json")]     [WebDispatchFormatterMimeType(typeof(WcfRestContrib.ServiceModel.Dispatcher.Formatters.FormUrlEncoded), "application/x-www-form-urlencoded")]     public class PublicAppointmentSchedulerSvc : IPublicAppointmentScheduler     {         IPublicAppointmentScheduler impl = new PublicAppointmentScheduler();         [WebDispatchFormatter]         [Description("Immediate or callback contact request")]         [WebInvoke(UriTemplate = "InitiateContact", Method = Verbs.Post)]  &n

Reuse XAML Declarative Workflow in Workflow Service (xamlx) Results in Server Error of System.Argume


We attempted to reuse a XAML (declarative activity workflow) in a few places within the same XAMLX and it doesn't appear to allow this.   On the WCF client side, it reported an obscure error of something to the effect of unknown message received and a communication error stating the service instance couldn't be used at this time and to ensure the call order is correct or order delivery guarantee is enabled.   However, this appears to mask the true issue which is on the server side.   Apparently, when the server side WCF end point is trying to start the workflow instance, it throws this error building a dictionary of workflow children...

Workflow Services: Visual Design of Workflows with WCF and WF 4


The .NET Framework 4 makes it easier than ever to implement WCF services using WF. We'll demonstrate just how easy it is by modeling a long-running, durable and instrumented workflow based on a real-world business case without having to write any code.

Foundations: Windows Workflow Design Patterns


Design patterns provide a common, repeatable approach to solving software development tasks, and many different patterns can describe how to accomplish a certain goal in code. When developers begin working with Windows Workflow Foundation (WF), they often ask about how to accomplish common tasks with the technology. This month's column discusses several design patterns used in WF.

Web Service Workflows: Deploy Distributed Business Processes With Windows Workflow And Web Services


Due to the distributed nature of a business process it makes sense for a workflow to be deployed as a distributed application. See how Windows Workflow and Web Services hold the key.

Design Patterns: Simplify Distributed System Design Using the Command Pattern, MSMQ, and .NET


Service-oriented architecture is a great framework when you need to perform distributed computing tasks over the Internet. But when you want to perform processing inside your local network, a different solution may provide a better fit. That solution, based on the Command pattern, uses Windows services and Microsoft Message Queuing to implement a queued system that meets your needs better than a service-oriented solution. This article explains how to build it.

Design: Place XML Message Design Ahead of Schema Planning to Improve Web Service Interoperability


Web Services are all about exchanging data in the form of XML messages. If you were about to design a database schema, you probably wouldn't let your tool do it for you. You'd hand-tool it yourself to ensure maximum efficiency. In this article, the author maintains that designing a Web Service should be no different. You should know what kind of data will be returned by Web Service requests and use the structure of that data to design the most efficient message format. Here you'll learn how to make that determination and how to build your Web Service around the message structure.

Exchange 2000: Web Storage System, Workflow Tools, and CDO Turbocharge Collaboration Apps


Microsoft Exchange 2000, the upcoming version of Exchange Server for Windows 2000, provides many new features including integration with Active Directory, Web Storage System events and forms, and a new version of Collaboration Data Objects (CDO). Exchange 2000 also provides a workflow engine and design tool to create workflow applications. This article will give you an overview of these new features and looks at ways to do a few standard tasks with the new version of CDO. Also included is a sample workflow application that manages the posting of messages to a public server to illustrate the new workflow engine and workflow design tool.

WCF Workflow Service Application - Required Extensions

Hello, I built a WCF Workflow Service App and I built a custom activity that requires an extension in the workflow. In a web app, I'm trying to create a service reference to the WCF workflow service but it says that an extension that is required has not been provided; so how do I consume a service with a required extension? At what point do I supply that extension in an ASP.NET scenario? Thanks. http://linkedin.com/in/brianmains

Custom sequence activity deriving from System.Workflow.Activities.SequenceActivity

Hi, I try to create custom sequence activity. I found some sample (http://social.msdn.microsoft.com/Forums/en-US/wfprerelease/thread/f54e8eb2-29d9-46f6-ad96-766fe6fad333/). But this custom activity looks ugly (to separate nested activity using ellipses instead of arrows). My question is - how to create custom sequence activity, which will look like sequence activity. I also found this sample - <ContentPresenter x:Uid="ContentPresenter_1" Content="{Binding}" Style="{x:Static sacdt:DesignerStylesDictionary.SequenceStyle}"/> When I used this ContentPresenter my custom activity looks like System.Workflow.Activities.SequenceActivity, but I couldn't put on it another activity. I also created class, which derives from System.Workflow.Activities.SequenceActivity, but I couldn't see it in toolbox. My question is - how to create class, which derives from System.Workflow.Activities.SequenceActivity and is visible in toolbox or how to use ContentPresenter for sequence activity, which allows put on itself another activity.

Workflow Service failing on high load

Hi, I am load testing my workflow service to ensure that it can sustain high loads for a high volume transaction application. I am using Visual Studio's Load Test to run on a simple unit test to call the workflow service. I have configured the bindings on my service as follows:  <bindings>      <netTcpBinding>        <binding portSharingEnabled="true" closeTimeout="00:10:00"                 openTimeout="00:10:00" receiveTimeout="00:10:00" sendTimeout="00:10:00"                 maxBufferPoolSize="20480000" maxBufferSize="20480000" maxConnections="10"                  maxReceivedMessageSize="20480000"  >                    <security mode="None" />        </binding>      </netTcpBinding>  &n
