I am following a tutorial ("Build real world application using ASP.NET Core MVC, Entity Framework Core and ASP.NET Core Identity") and I am at the point where I need to create the identity as a scaffold item. However, I seem to be running into an error that has to do with the bootstrap version I'm using, I'm just not sure what to do from here. "There was an error running the selected code generator: 'The specified bootstrap version '4' is not valid. The valid options are '3,4,5'."

I have updated my code generator but it didn't help.

I've encountered a similar problem. It seems that it is related to the recently released .Net 6. I've solved by switching back to .Net 5 and reinstalling all related packages and executing wizard in this environment. After that I migrated back to the .Net 6

There is a simpler work around. Remove the wwwroot/lib/bootstrap folder (I simply moved it to another holding location temporarily... It doesn't work to simply right click and exclude it from the project).

Do the scafolding and it should work... then put the folder back. Worked for me...
