I was trying to enable/configure basic workflow in sensenet back-end application. I performed the following steps and I am getting the error mentioned below.
Steps performed
I had enabled approval for one document library (Home / workspaces / Document Workspaces / London Document Workspace / Document library) in Sensenet demo server
I assigned workflow for approval and checked all 4 available options for initiating workflow
I created a new content and while uploading (all workflows were set to automatically execute), I got the following error
The following errors were encountered while processing the workflow tree:\n DynamicActivity : The private implementation of activity 1: DynamicActivity has the following validation error: Compiler error(s) encountered processing expression CType(StateContent( Workspace ), SenseNet.ContentRepository.GenericContent).Path & /Tasks .\nReference required to assembly netstandard, Version=2.0.0.0, Culture=neutral, PublicKeyToken=cc7b13ffcd2ddd51 containing the base class System.Object . Add one to your project.\n
How can I rectify this?
