Could not find type "InvokeWorkflowFile in namespace error message

Hi,

I have a workflow which calls other workflows using invoke workflow activity. We have come across an error where the invoke workflow activity could not be loaded because of errors in the XAML. I have checked the project dependencies and all packages listed are up to date so not sure what else I am missing here?

Any assistance would be much appreciated.

Regards,

Jeff
