It seems like the issue is because ApiControllerWithActions.cshtml is named ApiControllerWIthActions.cshtml by mistake!

ControllerGenerator contains de file MvcControllerWithContext.cshtml

You just have to copy the Template folders Template/ControllerGenerator and Templete/ViewGenerator to own project.

This is the path of the missing files: /home/$USER/.nuget/packages/microsoft.visualstudio.web.codegenerators.mvc/5.0.0/Templates

Building from the First MVC APP. During controller scaffolding:

I have messed with the dependencies that exist in MvcMovie.csproj, swapping versions in and out.

No joy.

I ran into the same problem following the MVC tutorial over at the Official Microsoft Documentation. Did you find a fix? I tried downgrading the dotnet-aspnet-codegenerator to 3.1.0 but that didn't work.

Awesome, good! I thought I'm the only dummy who can't follow simple tutorial. This official tutorial does not work with containers at all.

I was working on docker integration for a few days last week.

https://gitlab.com/whittington.andy/dotnet-api

The readme.md might help someone work through it.

The only fix for the dotnet-aspnet-codegenerator that I currently have been able to successfully use is to downgrade the tool. If that doesn't work, what error do you get after?

@whittingtonandy downgrading to any 3.x version below 3.1.4 gives me "No code generators found with the name 'controller'" instead

@whittingtonandy workaround worked for me. Using docker image mcr.microsoft.com/dotnet/core/sdk:3.1

dotnet tool uninstall --global dotnet-aspnet-codegenerator
dotnet tool install --global dotnet-aspnet-codegenerator --version 3.1.0

@pi3ch Downgrading from 3.1.4 to 3.1.3 worked for me. I guess this is some issue with the latest release of the package.

Just to update your workaround:

dotnet tool uninstall --global dotnet-aspnet-codegenerator
dotnet tool install --global dotnet-aspnet-codegenerator --version 3.1.3

Where specifically in the project should the files (or whole folders) be copied to?

EDIT:
I made a "Templates" Folder at the root of my application and copied the "ControllerGenerator" and "ViewGenerator" folders and that worked.

Thanks @ErikSmart !!!!

ControllerGenerator cont茅m o arquivo MvcControllerWithContext.cshtml

Voc锚 apenas tem que copiar as pastas Template Template / ControllerGenerator e Templete / ViewGenerator para o pr贸prio projeto.

Este 茅 o caminho dos arquivos ausentes: /home/$USER/.nuget/packages/microsoft.visualstudio.web.codegenerators.mvc/5.0.0/Templates

Utilizo ElementaryOS. Fiz como o @RkNjeru disse no EDIT e funcionou perfeitamente.
Obrigado <3
