1. Build a web form project with REST service components.
2. Publish it to IIS.
3. Try to run the form from StartDialog.aspx page.

The form will not load. You will see an error message.

Environment

ITMS 8.x

Workflow 8.x

Cause

The JSON core library called Newtonsoft.JSON.dll is not added to the published version of the project.

Resolution

As a workaround, add the Newtonsoft.Json.dll manually to the project, and, while publishing, make sure it is listed under Libraries tab, and properly checked in Publish checkbox. You can also copy the file to the ...Program Files\Symantec\Workflow\Shared folder so that it can be referenced.

NOTE: In one case the Newtonsoft.Json.dll also had to be manually place in the C:\Program Files\Symantec\Workflow\WorkflowDeploy\Release\CT.WS.IG.SYM\bin folder.
