I am working on SharePoint Server 2013 with Workflow Manager,When I tried to create a new empty SharePoint solution then I added a workflow item where the workflow designer faild to show activity,I tried to build the solution but unfortunately, I got the following error:
Workflow Manager Tools need to be installed to build this project.
This problem usually occurs because Office Developer Tools was not updated for Aug update.
To fix the SharePoint workflow designer issue.follow the mentioned steps below :
- Install the Aug update for Office Developer Tools from Office Developer Tools for SharePoint 2013 Update (Note:change the extension to .exe)
- Again, open your project, the SharePoint workflow designer should now been worked.
