ASP.NET Core Scaffolding does not work in VS 2017
I have a beginner ASP.NET Core project in Visual Studio 2017, and I am at the scaffolding step of the HelloWorld. The Scaffolding does not work, I tested on a first computer, then at a second one...
when I try to generate a controller with views
, it gives the following error on the first machine:
Microsoft Visual Studio
Error
There was an error running the selected code generator:
'Unhandled Exception: System.IO.FileNotFoundException: Could not load file or assembly 'Microsoft.VisualStudio.Web.CodeGeneration.Utils, Version=1.1.1.0, Culture=neutral, PublicKeyToken=adb9793829ddae60'. The system cannot find the file specified. at Microsoft.VisualStudio.Web.CodeGeneration.Design.Program.Main(String[] args)'
OK
On the second machine:
Microsoft Visual Studio
Error
There was an error running the selected code generator:

Answer
The following works for me.
I deleted bin & obj folders, build the project again and it works.
In case if it gives you error: it couldn't find project.deps.json in debug folder.
Set project to debug, ran it and now you can add scaffolded items.
