Import "Microsoft.WebTools.Scaffolding.Core.ScaffolderFactory.FactoryConfigEvaluator" could not be satisfied

Question

I am using Microsoft Visual Studio Community 2019 Preview - Version 16.8.0 Preview 1.0 . I try to scaffolding ASP.NET Core Identity files. I catch error

Import "Microsoft.WebTools.Scaffolding.Core.ScaffolderFactory.FactoryConfigEvaluator" could not be satisfied.

How to fix it?

Answer 1

Go to %ProgramData%\Microsoft\VisualStudio\Packages

Find something like this

Microsoft.VisualStudio.Web.Scaffolding,version=16.6.741.31162,chip=neutral,language=en-US

For example, full path

"C:\ProgramData\Microsoft\VisualStudio\Packages\Microsoft.VisualStudio.Web.Scaffolding,version=16.6.741.31162,chip=neutral,language=en-US"

Close Visual Studio. Delete all files inside this folder. Launch Visual Studio Installer. choose Repair.

caution: disadvantage, the download file size is too large (4.8 GB)
