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.

Solution

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

You will can refer .Net Standard 2.0 projects and dlls in workflow foundation project templates and use without any issue.

  1. An absolutely identical error was at installation Visual Studio 2012 on Windows 10.
    When I faced it I had to surf many forums before I found that special file which was necessary and recover msvcp140.dll missing https://fix4dll.com/msvcp140_dll. In principle, last stage, after a lengthy setup and compilation by all sides has been gained I also reached pretty success in Visual Studio project.
