What Visual Studio version are you on? This is a known issue with 16.8 Preview 2

jabjack commented 4 years ago

Visual Studio 2019 , Version: 16.6.2

Getting the same error when trying to add scaffolding, its trying to install version 5.0.2 (current latest) but fails to do so.

What worked for me was manually installing an earlier version

Install-Package Microsoft.VisualStudio.Web.CodeGeneration.Design -Version 5.0.1

@steroyle What is the error you get when it fails to install? I also recommend after an install to just rebuild the project. That in the past has resolved a ton of dependency issues.

Let me know, Deep

I Fixed it!! --> Rebuild Project --> Exit Visual Studios --> Re-load and it works :)

don't choose a layout page when you are going to choose a model to create a view . In this way you can avoid this error. Same error was thrown to me but then i deselected layout + reference scripts then microsoft.visualstudio.web.codegeneration.design installed successfully.
