  • No, but if it is the right type of activity it will have this access already. You would need to use a custom NativeActivity, and then you can inspect the NativeActivityContext in the Execute override of the custom activity. This will give you access to all the features of the runtime, when a CodeActivity derived activity only gives you access to the arguments passed into the activity. Here are some additional details about the types of base classes available for custom activity authoring:

    Are you needing a reference to the currently running workflow that the activity is in, or another workflow or type of workflow? What is your scenario and if we can't do it exactly the way you envision we might be able to find an alternate way.
