I wanted to create a new Web API Controller by adding a new scaffolded item. As I try to name my new controller, I get the following error:

There was an error running the selected code generator: 'The value -1 is outside the acceptable range of [0,2147483647]. Parameter name: value'

This error seems to occur with any name, e.g. "DefaultController"

Is anyone familiar with this error?

A clipart of the error window in case it is of any help:
