Entity Framework Method 'Identifier' in type 'Microsoft.EntityFrameworkCore.Design.Internal.CSharpHelper' from assembly 'Microsoft.EntityFrameworkCore.Design, Version=8.0.0.0, Culture=neutral, PublicKeyToken=adb9793829ddae60' does not have an implementation.

 

Quando si sviluppano applicazioni con EntityFramework Core, può capire di ricevere il messaggio di errore "Method 'Identifier' in type 'Microsoft.EntityFrameworkCore.Design.Internal.CSharpHelper' from assembly 'Microsoft.EntityFrameworkCore.Design, Version=8.0.0.0, Culture=neutral, PublicKeyToken=adb9793829ddae60' does not have an implementation." quando si esegue il comando scaffold.

Questo perchè tra i vari pacchetti manca "Microsoft.EntityFrameworkCore.Design".

I pacchetti da aggiungere al programma sono: 

"Microsoft.EntityFrameworkCore.Design"

"Microsoft.EntityFrameworkCore"

"Microsoft.EntityFrameworkCore.SqlServer"

"Microsoft.EntityFrameworkCore.Tools"
