```aspnet-codegenerator``` can't handle model with composite key
Hello,
I tried to use the aspnet-codegenerator with a model that has a composite key. This is the model I've used:
using System.ComponentModel.DataAnnotations;
namespace mynamespace.Models
{
public enum Location
{
Index,
Mail,
Alle
}
public class InfoText
{
[Display(Name = "Anzeigeort")]
public Location Location { get; set; }
[Display(Name = "Datum Ab")]
public DateOnly Datab { get; set; }
[Display(Name = "Datum Bis")]
public DateOnly Datbi { get; set; }
[Display(Name = "Inhalt")]
public String Content { get; set; }
}
}
I want the key to be a combination of Location, Datab and Datbi.
Since I can't provide the composite key via annotation, I've used the OnModelCreating method in the context:
protected override void OnModelCreating(ModelBuilder modelBuilder)
{
modelBuilder.Entity<InfoText>().HasKey(e => new { e.Location, e.Datab, e.Datbi });
}
This works fine during runtim, but now I wanted to generate the Razor Pages for my model, with the following command:
dotnet aspnet-codegenerator razorpage -m Infotext -dc MyContext -outDir Pages\Admin\Infotext -l _AdminLayout -scripts
Sadly this command fails with the following output.
Building project ...
Finding the generator 'razorpage'...
Running the generator 'razorpage'...
Minimal hosting scenario!
Attempting to compile the application in memory with the modified DbContext.

warn: Microsoft.EntityFrameworkCore.Infrastructure[10410]
'AddEntityFramework*' was called on the service provider, but 'UseInternalServiceProvider' wasn't called in the DbContext options configuration. Consider removing the 'AddEntityFramework*' call, as in most cases it's not needed and may cause conflicts with other products and services registered in the same service provider.
The entity type 'MigrationOperation' requires a primary key to be defined. If you intended to use a keyless entity type, call 'HasNoKey' in 'OnModelCreating'. For more information on keyless entity types, see https://go.microsoft.com/fwlink/?linkid=2141943. StackTrace:

It seems like the generator doesn't recognize that I've set the composite key in my context.

EF Team Triage: Closing this issue as the requested additional details have not been provided and we have been unable to reproduce it.
BTW this is a canned response and may have info or details that do not directly apply to this particular issue. While we'd like to spend the time to uniquely address every incoming issue, we get a lot traffic on the EF projects and that is not practical. To ensure we maximize the time we have to work on fixing bugs, implementing new features, etc. we use canned responses for common triage decisions.
