Automapper 11.0.0 NÃO funciona no .Net Framework???

Olá!

Eu estou fazendo a aula "Mapeando objetos com o AutoMapper" dentro do "05. Melhorando o código" e o instrutor usou a versão 8.1.1 do Automapper. Mas a última versão disponível hoje é a 11.0.0.

Infelizmente deu erro em tudo ao processar no Postman e no Swagger ...

... fui pesquisar a documentação do Automapper e para minha surpresa encontrei o texto:

==========================================================

11.0 Upgrade Guide / 11.0 Guia de atualização

AutoMapper now targets .Net Standard 2.1 and doesn’t work on .Net Framework

O AutoMapper agora tem como alvo o .Net Standard 2.1 e não funciona no .Net Framework

https://docs.automapper.org/en/latest/11.0-Upgrade-Guide.html#automapper-now-targets-net-standard-2-1-and-doesn-t-work-on-net-framework

==========================================================

Isso quer dizer que miou tudo, pois o instrutor está usando o ".Net 5"? (eu estou usando o ".Net 6")

Bom... o projeto NÃO tem nenhum erro na lista de erros, então decidi fazer um "downgrade" de versão:

Eu acreditei que funcionaria numa boa, mas infelizmente apresentou o mesmo erro:
