The Visual Studio 2010 Workflow Designer supports not only standard Visual Studio debugging features such as breakpoints and call stack windows, it also includes a range of visual indicators that provide information during the debugging process.
Has someone a glue if jBPM is a better flowengine than Microsoft Windows Workflow Foundation ?Microsoft Visual studio 2005 has a very nice designer compare to the JBOSS 1.5 eclipse designer. But that is only on the surface. What about under the surface ?C# and Java is not an issue (I love them both). I know that Java is more platform friendly (+JBoss). But I'm also seeking a quality flow engine that exist also in to years time and is easy to use !Tore Gard =5C080096-F3A0-4CE4-8830-1489D0215877&displaylang=en
Visual Studio 2005 – Windows Workflow Foundation
I followed all the above troubleshoot solutions and found the below site to help me troubleshoot. In my case, I installed visual studio before installing SharePoint Designer. The solution was to uninstall Visual Studio and install again.
Also, custom activities can be developed for additional functionality. Activities can be assembled visually into workflows relying on the workflow designer, which is a design surface that runs within Visual Studio. The designer can also be hosted in other apps.
Welcome to this installment of the .NET Nuts & Bolts column. This article will walk through building a state machine workflow, which is one of the several workflow types supported by the Microsoft .NET Framework 3.0 and Visual Studio 2005.
Use the following outlined steps to create a state machine workflow within Visual Studio 2005. There are a number of steps to describe as you walk through the example. As with any set of detailed instructions, you may have to read through them carefully a few times to ensure you catch all of the parts.
Now let's look at the workflow again in Visual Studio. I use Visual Studio 2008, the samples are made for Visual Studio 2005 with the Visual Studio 2005 Extensions for .Net Framework 3.0 (Windows Workflow Foundation).
Windows Workflow Foundation is supported by a companion set of extensions to Visual Studio 2005. These extensions contain a visual workflow designer which allows users to design workflows, a visual debugger which enables the users to debug the workflow designed, and a project system which enables the user to compile their workflows inside Visual Studio 2005. In Visual Studio 2008 the WF functionality is included without any extensions to install.
Windows Workflow Foundation also includes Visual Studio 2005 extensions. These extensions contain a visual workflow designer which allows users to design workflows, a visual debugger which enables the users to debug the workflow designed and project system which enables the user to compile their workflows inside Visual Studio 2005.
One of the benefits to using XML is the large number of tools with the ability to read, modify, create, and transform XML. XML is tool-able. Compared to parsing C# code, it would be relatively easy to parse the XML and generate a visualization of the workflow using blocks and arrows. Conversely, we could let a business user connect blocks together in a visual designer, and generate XML from a diagram.
Let's think about what we want in a workflow solution. We want to specify workflows in a declarative manner, perhaps with the aid of a visual designer. We want to feed workflow definitions into a workflow engine. The engine will manage errors, events, tracking, activation, and de-activation.
All activities in WF derive from an Activity base class. The Activity class defines operations common to all activities in a workflow, like Execute and Cancel. The class also defines common properties, like Name and Parent, as well as common events like Executing and Closed (the Closed event fires when an Activity is finished executing). The screenshot below shows the Activity class in the Visual Studio 2005 class designer:
Microsoft also provides the Microsoft Visual Studio 2005 Extensions for Windows Workflow. These extensions plug into Visual Studio to provide a number of features, including a visual designer for constructing workflows. A screenshot of the visual designer is shown on the next page.
Another job of the workflow designer is to provide validation feedback for the activities in a workflow. Each activity can define its own design-time and run-time validation. The designer will flag an activity with a red exclamation point if the activity raises validation errors. For example, a CodeActivity will display a red exclamation point until we set the ExecuteCode property. Without a method to invoke, the CodeActivity is useless, but the validation catches this problem early and provides visual feedback.
Visual Studio allows developers to write extensions for Visual Studio to extend its capabilities. These extensions "plug into" Visual Studio and extend its functionality. Extensions come in the form of macros, add-ins, and packages. Macros represent repeatable tasks and actions that developers can record programmatically for saving, replaying, and distributing. Macros, however, cannot implement new commands or create tool windows. They are written using Visual Basic and are not compiled.[12] Add-Ins provide access to the Visual Studio object model and can interact with the IDE tools. Add-Ins can be used to implement new functionality and can add new tool windows. Add-Ins are plugged into the IDE via COM and can be created in any COM-compliant languages.[12] Packages are created using the Visual Studio SDK and provide the highest level of extensibility. They can create designers and other tools, as well as integrate other programming languages. The Visual Studio SDK provides unmanaged APIs as well as a managed API to accomplish these tasks. However, the managed API isn't as comprehensive as the unmanaged one.[12] Extensions are supported in the Standard (and higher) versions of Visual Studio 2005. Express Editions do not support hosting extensions.
The final release of Visual Studio 2013 became available for download on October 17, 2013, along with .NET 4.5.1.[190] Visual Studio 2013 officially launched on November 13, 2013, at a virtual launch event keynoted by S.

Professional software developers Professional software developers can create workflows by using the Microsoft Visual Studio 2005 Extensions for Windows Workflow Foundation. These workflows contain custom code and workflow activities. After a professional developer creates a custom workflow, a server administrator can deploy that workflow across multiple sites. 2ff7e9595c
