WF 4.0 Designer Rehosting: we’ve see the light!!

How many times I’ve written about Workflow Designer Rehosting feature inside Windows Workflow Foundation? Too many times I think… If you’ve done projects with WF 3.5 and you’ve tryed to make in production the Designer Rehosting feature, you can understand what I mean: in WF 3.5 hosting the Workflow Designer inside an application (a WPF application for example) is too hard, not so flexible and not so intuitive for the end user. I’ve received many answer from the WF Dev Team in the past about this topic and they said me that the things will change with the...

Windows Workflow 4.0: quick Activity reference

The .NET Endpoint Team has published an interesting post where they give a brief description on all the new activities that ships with the WF 4.0 Beta 1 platform.

This is the main content of the summary (cross posted here for don’t loose it): Activities are the unit of work in a workflow program. Activities in WF4 have a signature and body. The signature of an activity is defined in terms of its...

Windows Workflow 4.0

In an interesting post, Cliff Simpkins (senior product manager in the .NET product marketing group for Windows Workflow Foundation) has shared other news about the future Workflow platform. I think that everyone of us that is involved on developing large .NET applications that makes use of Windows Workflow for certain business process, are a bit worried about the future direction of this platform. The common question is: if I write a .NET application that uses WF 3.5 now, should I rewrite it the next year or when WF 4.0 will be released? In this post Cliff explains the key concepts:...

Extending Dynamics NAV with Windows Workflow

Frequently I'm involved on speaking where we present products like Dynamics NAV, Dynamics CRM, Sharepoint and all the new .NET 3.5 platform in general. One of the common aspects that I like to put in evidence is that all these products (except NAV) supports natively one of the coolest aspects of the new .NET platform: Windows Workflow (it's not a mistery that I'm a Windows Workflow lover and I like to show that with Windows Workflow you can build modular business processes). One of the common question that often I receive is: can we extend Dynamics NAV with Windows...

Exposing Windows Workflow as an XML Web Service: what about persistence?

In these days I was involved on the migration of lots of my services under the new .NET 3.5 platform (WCF and WF). Today I've tryed to expose a Windows Workflow as an XML Web Service and now I've a dilemma... :) OK... let's go from the beginning... With Windows Workflow is quite simple to expose a WF as an XML Web Service. Start Visual Studio 2008, New Project and choose Sequential Workflow Library: Then, exactly like WCF, you need to define an interface that will act as the interface to the workflow (I've used VB.NET in my project): Interface IWS         Function MyMethod(ByVal Input...

No Certification Training Kits for Windows Workflow...

Some days ago Gerry O'Brien published on his official Microsoft Certification blog a summary of the planned Training Kits for Visual Studio 2008 and .NET 3.5 Certifications and their current expected release dates (plus some news about Training Kits for SQL Server 2008). My surprise was to see that in this list there's a planned Training Kit for WPF, a planned Training Kit for WCF but no planned Training Kits for Windows Workflow. Fortunately Microsoft has planned also an exam for this new technology (Exam 70-504: TS: Microsoft .NET Framework 3.5, Windows Workflow Foundation Application Development) so why not having...

Windows Workflow Designer Rehosting: what we need...

Some weeks ago I was invited to leave feedbacks on a survey published by Microsoft about the next version of the Workflow Designer. One of the coolest feature about the actual WF Designer is that you can rehost it inside any custom application (for example a Winform application) and you can enable your end users to edit processes or simply to to visualize and monitor the workflow state. For my little experience I've done in these months on trying to rehost the WF Designer, I can say that it's not so easy as someone could imagine. However, despite the difficulties...

Sharepoint Workflow package generator

On the last VSTO Power Tools package there's an interesting SharePoint Workflow Package Generator, a simple tool that creates a WSP file from a VS 2008 SharePoint workflow project. As described by Nikhil Kothari's announce: The package generator uses the feature.xml file to generate a WSP file. In the WSP file, it will also include any <ElementFile> that have been referenced. Hence, any referenced InfoPath forms and resource files will also be packaged in the WSP file. To use the package generator just type: “c:\Program Files\Microsoft VSTO Power Tools 1.0\workflowpackagegen.exe" /featureManifest:feature.xml " An example of incorporating the tool into...

One of the key concept of the new Microsoft® .NET Framework 3.0 platform is absolutely Windows Workflow Foundation (WF), the framework that enables you to build sequential and state-driven workflow capabilities into your existing applications.
