Release Notes

Interface selection dialog hides nested interface types

The interface selection dialog in the Visual Studio 2005 Extensions for Windows Workflow Foundation does not show interface types that are nested within other types.

Cannot select overloaded method names on CallExternalMethodActivity

If you have two or more methods on a CallExternalMethodActivity activity with the same name but different parameters, you will be unable to select unique versions of the methods in the dropdown in the workflow designer. Any overloaded method you select will automatically default to the first method defined in your activity. Use unique method names to avoid this problem.

Cannot invoke another workflow in same Visual Studio project

A workflow cannot invoke another workflow in the same Visual Studio project; the second workflow will not appear as an option for the InvokeWorkflow.TargetWorkflow value.

Error while detaching from workflow debugger

The debugger provides the error message "Unable to detach from the process" to you if you try to detach from the process being debugged explicitly using Detach All in the Debug menu. This error can also occur if you attach to multiple processes during debugging and click Stop Debugging in the Debug menu.
