How do you extend a Windows Workflow Receive Activity to put objects onto the context for downstream activities to use?

I am working on many workflows for a project I am on. In all of the work flows, when we execute the Receive Message activity we need to take some info from the message, do a DB query and then use the resulting (POCO) results in all of the following activities. What I am looking for in thsi question is a way to load my data record into a POCO then set it on the workflow's context so it is available to all activities downstream.

Some examples I have found state there is a Properties property on StateActivity only I am not finding it. It is almost like the class does not allow Properties anymore. I am looking at this SO question: Accessing Arguments, Workflow Variables from custom activities

Any ideas on how to accomplish this? I don't particularly want to set it as an OutArgument and then consume it everywhere as an InArgument.

I am working with WWF 4.

TIA

Solution

  • Using the context.Properties is correct way of doing this. Note that the Properties collection is not part of a StateActivity but of the execution context passed to a CodeActivity or a NativeActivity.
