Where are SendAndReceiveReply and ReceiveAndSendReply?

Question

I've re-hosted the workflow designer and must say that I'm very impressed, but there's 2 activities that appear when hosted in VS that I can't find - SendAndReceiveReply and ReceiveAndSendReply. I managed to find the other messaging activites hiding in System.ServiceModel.Activities, but these last 2 are proving somewhat elusive.

Anyone know where they live? Are they in fact a 'VS special'?

Regards,

Nigel

Answer 1

you need to go to following path to get them

System.Activities.Core.Presentation.dll

namespace System.ServiceModel.Activities.Presentation.Factories

ReceiveAndSendReplyFactory

SendAndReceiveReplyFactory

Answer 2

you can use following code to add sendAndReceiveReply
ToolboxControl control = new ToolboxControl();
ToolboxCategory cat = new ToolboxCategory();
ToolboxItemWrapper wrap = new ToolboxItemWrapper(typeof(SendAndReceiveReplyFactory));
cat.Add(wrap);
control.Categories.Add(cat);

 the same as ReceiveAndSendReply
and add the reference System.Activities.Core.Presentation.dll
and using System.ServiceModel.Activities.Presentation.Factories;

Answer 3

(Random related tip hoping to forstall a later FAQ: in your toolbox you should also use the ForEachWithBodyFactory and ParallelForEachFactory in the S.A.C.P assembly, rather than System.Activities.ForEach<T> etc.)

Answer 4

...and I presume I should replace System.Activites.Pick with System.Activities.Core.Presentation.Factories.PickWithTwoBranchesFactory?

Answer 5

for parrallelforeach, you should use ParallelForEachWithBodyFactory<> in toolbox
for foreach, you should use ForEachWithBodyFactory<>
for pick, you should use PickWithTwoBranchesFactory

Answer 6

Thanks a lot. I now have all activities showing up (with their correct icons thanks to http://blogs.msdn.com/asgisv/archive/2010/02/10/displaying-net-framework-4-built-in-workflow-activity-icons-in-a-rehosted-workflow-designer.aspx).

Just to confirm - you have to pick up activities from: -

System.Activities.Statements
System.ServiceModel.Activities

and you have to pick up factories from: -

System.Activities.Core.Presentation.Factories
System.ServiceModel.Activities.Presentation.Factories

You use factories for: -

ForEachWithBodyFactory<T> for ForEach<T>
ParallelForEachWithBodyFactory<T> for ParallelForEach<T>
PickWithTwoBranchesFactory for Pick
ReceiveAndSendReplyFactory for ReceiveAndSendReply
SendAndReceiveReplyFactory for SendAndReceiveReply

N.B. - The article explaining how to pick up the correct icons has a bug in the sample. You just need to strip the `1 off the end of the type name if it's a generic type, before using it as a resource key, or you won't find the bitmap!

You've certainly spread the information around, but it does all work if you hunt it down - a huge improvement on WF3 designer re-hosting experience!

Thanks for all the help:-)

Hi Nigel,

Do you know where I could get the icons for the System.ServiceModel.Activities?  The System.Activities.Statements icons load correctly but the servicemodel.activities do not. Any help would be appreciated. Thanks!
