In an existing Workflow 2013, I want to add a stage and/or a step to the workflow that is not included in Workflow 2013. I want to change permissions on a custom list item once the item has been submitted to the workflow. I want to write some .net 2012 code to accomplish this task. I basically want to add the .net code to the one area in the worklow 2013 that I am referring to.
Thus can you show me the following:
1. How to 'wire together' .net 2012 code into the one stage/step in the existing workflow that was created by SharePoint Designer 2013?
2. Would you show me the .net code to change be used to decrease the security level on the submitted list to view and/or read only?
