Error scaffolding Identity Fails the second time after using CLI code generator

Question

Hi I ran the code generator once to scaffold the login and register pages. Then I ran it again because I needed to scaffold the password page but it wouldn’t build and I got errors. I am using vs studio for Mac and the cli commands to scaffold pages.
Any help Is appreciated.

Here is the code I ran the first time: dotnet aspnet-codegenerator identity -dc TimeClock.Data.ApplicationDbContext --files "Account.Register;Account.Login”

Here is the code I ran the second time: dotnet aspnet-codegenerator identity -dc TimeClock.Data.ApplicationDbContext --files "Account.ForgotPassword"

Error I get

...error CS0433: The type 'SignInManager' exists in both 'Microsoft.AspNetCore.Identity, Version=7.0.0.0, Culture=neutral, PublicKeyToken=some# and 'Microsoft.AspNetCore.Identity, Version=2.0.4.0, Culture=neutral...

Hi @ThunderBox

Whether your application is an Asp.net 7 or Asp.net core 2 application? From the error message, it seems that your project having two different versions of the same assembly, to resolve this error, use the alias feature of the (References) compiler option or do not reference one of your assemblies.

Then, clean and rebuild your application.

More detail information, see Compiler Error CS0433.
