(WF4)(PU3) Picking apart SendReceiveExtension

Last time I mentioned there is something new in Platform Update 3 Beta called SendReceiveExtension. I still don’t know much about it other than the general reason for adding it to the .Net framework, which is basically to allow non-.Net classes to play the role of .Net’s WorkflowServiceHost class (System.ServiceModel.Activities). Remember this stuff is all…

Platform Update 3 Beta

G’day all, just a little snippet of news to share – remember .Net 4 Platform Update 1? The update with State Machine? Well, we are almost up to Platform Update 3 now, and the beta version is available for download. Note that this is not the final PU3, this is just a beta version of…

(WF4) Adding VB namespace Imports to your workflow programmatically

These questions (paraphrased) have come up a bunch of times so it’s not that hard to find the answer, but I just rediscovered them so it’s on topic for today. “I want to add a namespace to the Imports designer automatically at design time, so the user doesn’t have to do it manually. How can…

(WF4) WF4 Sessions from //build/

As I mentioned earlier this week there were two WF focused sessions at //build/ this week. Now they’re done, but the videos are available online. Of course, also this week, at //build/ the developer previews of Windows 8, .Net Framework 4.5, and Visual Studio 11 were announced. For VS and .net you can even go…

(Work) Tool of the day – ‘clip.exe’

Today I was writing a batch file to do make a process semi-automatic. One of the non-automatic stages is copy and pasting some text into a web interface. “It’d be pretty cool” I thought, “if I could just add a line to my batch file saying ‘place %text% on clipboard’” Well, it turns out someone…

(WF4, #bldwin) WF4 at //Build/

//Build/ is finally on! Session schedules are out, and I just wanted to let people know that there will be a couple WF sessions there in case there are any workflow-interested-attendees. Both the sessions are Friday, one at 12:30 PM (Ron Jacobs [twitter]) and one at 2:00 PM (Josh Twist [twitter]). “Building event-driven, long-running apps…

(WF4) ExpressionTextBox Expression Property and ArgumentToExpressionConverter

There are many examples of binding ETB, but I notice they tend to be short on the details of why the example code looks as it does. Maybe it is because we are short on the ‘why’ that people can get a little lost once they want to do something other than the well-documented scenarios…

(Work) In which mklink gives me back my hard disk space

I’m always getting frustrated by little problems at work. One by one they are tiny but gradually they add up. Especially if they happen again and again every day! Running out of hard disk space on my C: drive on one of my machines is one of the ones which continually reoccurs. Usually it’s right…

(WF4) Hosting the WorkflowDesigner (or other WPF stuff) in a separate AppDomain

A little while I begin a new rehosted designer project, and this time I want to get a little bit more creative with it, mixing in some of the stuff I have done earlier with XAML compilation. The more functionality like that I add, the closer to the Visual Studio scenario the scenarios it is…

(WF4, Toolbox) Updating the WF4 Toolbox Icon FAQ (for Rehosting and Custom Activities)

Introit – call it whatever, but today I’m recycling an old post. And I have one more little confession. When I started writing a new rehosted app today, I found out my old toolbox FAQ was fairly useless. It was even getting to the point where someone had to post this in the forum: “I…
