How can I do ASP.NET MVC view scaffolding in Rider IDE?

But you still can...

You can use dotnet aspnet-codegenerator terminal tool. which is used for generating controllers and views with different options.

Install the tool globally.

dotnet tool install --global dotnet-aspnet-codegenerator

dotnet aspnet-codegenerator controller -name MyNewController -m MyModel -dc MyDbContext -outDir Controllers/
