Part 1 part 2 Part 3 Part 4 You may recall my previous posts about using the TransactionScopeActivity within a ReceiveActivity and all the nasty issues we ran into. Just in case you want to read them again: one , two and three . As it turn out this is...
As far as I am concerned Silverlight 2 is pretty cool and should have been developed years ago . Well guess that isn't the case but it is here now. One thing I like about Silverlight is how easy it is to call a web service. I guess that is a must...
.NET Reflector, by Lutz Roeder, must be one of the most useful tools I have when developing .NET code. Usually it is the first thing I install right after Visual Studio not even waiting until I need it because I know I will. So the big news is that Red...
Part 1 part 2 Part 3 Part 4 In two previous blog posts, part one and part two , I covered the fact that the ReceiveActivity and the TransactionScopeActivity don't work together very well. I demonstrated this using a sequential workflow and did show...
It is available from the subscriptions download at http://msdn.microsoft.com/en-us/subscriptions/default.aspx Get it while it is hot Enjoy!
Part 1 part 2 Part 3 Part 4 In a previous blog post I write about what happens when you place a TransactionScopeActivity within a ReceiveActivity and an exception occurs that is supposed to roll back the transaction. In short the story was very bad and...
Part 1 part 2 Part 3 Part 4 I got an email from a friend last week asking about using a ReceiveActivity and, while receiving, using a TransactionScopeActivity to transitionally save some data in a database. Seems like a common enough scenario right? Well...
Afgelopen jaar hebben we het eerste CodeCamp in Nederland georganiseerd en dat was een groot succes. De meeste deelnemers vroegen om meer, sommige zelfs om een CodeCamp per kwartaal of een heel weekend lang. Nou hebben we dat laatste nog niet gedaan maar...
VS2008 SP1 Beta is quite a package. By default the installation downloads the packages as needed and when needed. Now that is just fine if you only need to install a single machine. But when you need to install multiple, possibly virtual, machines like...
When I tried I received the following very helpful System.ServiceModel.ProtocolException with Message="The remote server returned an unexpected response: (407) Proxy Authentication Required ( The ISA Server requires authorization to fulfill the request...
I recently received a copy of Pro WCF: Practical Microsoft SOA Implementation so I could review it. So did I like the book? Not really The problem with the book is that it wants to cover far too much and diverse material. Now covering a lot of material...
The new ReceiveActivity and SendActivity that marry Windows Workflow Foundation (WF) and Windows Communication Foundation (WCF) are really cool . Getting started is easy because a new Sequential Workflow Service Library, found under WCF instead of Workflow...
In a previous blog post I showed how to use the ReceiveActivity with long running workflow and how to extract the workflow instanceId from the context using the IContextManager. I also showed how to rebuild this context at a later date when you use a...
In my last post I showed how to self host the workflow runtime and still be able to use a Windows Communication Foundation and ReceiveActivity. Hosting the workflow runtime in a WorkflowServiceHost is nice but in all likelihood you will also need to configure...
One of the new, and pretty cool, Windows Workflow Foundation features is the ReceiveActivity that unleashes the power of Windows Communication Foundation to Windows Workflow Foundation. Getting started with a ReceiveActivity is quite simple as long as...
Next march 28 we are hosting another SDE event in Ede, the Netherlands. There is an impressive list of speakers and sessions, check it out here . I will be doing a session about the new Workflow Foundation features in the .NET framework 3.5. These new...
Using a ReceiveActivity is a great way of exposing a workflow via a WCF proxy. Get started by creating a new project based upon "Sequential Workflow Service Library". This is found in the WCF projects node instead of the Worflow projects node...
One of the nifty features in Windows Communication Foundation is duplex requests. To define a duplex request you need to create two interfaces, both with their OperationContract marked with IsOneWay:=True. The request interface also contains a CallbackContract...
I actually missed the release or the WCF activities for windows workflow a few weeks back but Marcel de Vries did a demo yesterday as part of his presentation at the SDE meeting. And I must say its an impressive piece of work that includes the whole enchilada...
Talking about conferences we pretty much finalized the session schedule for the SDC this year as well. And the session schedule is even more impressive as last year. We are holding back on publishing it for a bit longer until we have confirmation from...
