I'm trying to scaffold controller for Entity Framework Core using ASP.NET Core Web API .NET 6.0. Everything builds and I can add migrations and update database. When I try to scaffold controller I get this error..
This is my Startup

I have only one reference to Microsoft.AspNetCore.Identity
I tried unistall and install all packages but nothigs works, I have no idea what to try next.
EDIT
I use SignInManager in referenced project "Data" layer and temporarly removed and used UserManager for check password...(I see SignInManager class in startup is using namespase "Microsoft.AspNetCore.Identity" but I don't know from what package, and in Data project i need to install Microsoft.AspNetCore.Identity package 2.2.0 if I want to use it!!!!???) Without reference to "Microsoft.AspNetCore.Identity" package 2.2.0 now the error is different but still can't fix it.
CodePudding user response：
Remove the Microsoft.AspnetCore.Identity package, it is no longer needed.

Based on this article https://docs.microsoft.com/hr-hr/ef/core/cli/dbcontext-creation?tabs=dotnet-core-cli there was a problem creating DataContext at design time. I added this class and now scaffolding is working.
public class DataContextFactory : IDesignTimeDbContextFactory<DataContext>
{
public DataContext CreateDbContext(string[] args)
{
var configuration = new ConfigurationBuilder()
.SetBasePath(AppDomain.CurrentDomain.BaseDirectory)
.AddJsonFile("appsettings.json")
.Build();
var optionsBuilder = new DbContextOptionsBuilder<DataContext>();
optionsBuilder.UseSqlServer(configuration.GetConnectionString("KasicaConnection"));
return new DataContext(optionsBuilder.Options);
}
}
