Sharepoint 2013 & Custom Task Outcome on VisualStudio

This is the how it works:


Add new SiteColumn

Change the Type param value to "OutcomeChoice" in <Field /> tag

Add :   <CHOICES >

                <CHOICE>choice one</CHOICE>

                <CHOICE>choice two</CHOICE>

          </CHOICES>

Add new ContentType  and inherit from Workflow Task (SharePoint 2013)

Add Columns: 

• % Completed
• Task Status
• The custom OutcomeColumn

NB: The order is Important, if the custom Outcome Column is not the last one choices will appear as a DropBox and to as buttons

Add new Task List Instance (Or a Custom list template)

Insure the TemplateType is set to "171" (this Id reference Task template)

If you are working with a Task list Instance Add Schema.xml file to it and copy content from a Task list template (create a new Task list template, copy schema.xml content, modify List Name and URL to match your List Instance )

Deploy and happy to help you.

Please let me know if there is any issue so i can update this article
