[Bug] ambiguous method call 'ServiceCollectionExtensions.AddHandlebarsTransformers

[stephenburrows]

Since the update to version 6 I get ambiguous method call when performing a file name transformation

services.AddHandlebarsTransformers(entityFileNameTransformer: n => schemea + "." + n)

only seem to work if you preform all the transforms as show in your code example but in my case i only want to prefix models with their corresponding scheme name,
