Cannot add .Net Standard 2.0 Class as .Net Type in Workflow Foundation Activity Designer projects in Visual Studio 2017

Introduction

I was working on Workflow Foundation 4.5 using Activity Designer Library template in Visual Studio 2017.

Problem Background

When I try to add a class library as input Type through Type Browser in Activity designer it shows an error as “The selected type could not be created” as shown in the image below.

I compared another machine with the latest update of Visual Studio which was working fine. The problem seems to be I didn’t have .Net framework 4.6.2 SDK and .Net framework 4.7 SDK installed.

I modified the Visual Studio as below using Visual Studio Installer.
