Private mapper do not work when the parent class implement an interface.

Describe the bug

I have the basic setup:

internal sealed class UserWithClaims : IUser
{
   private readonly IdentityUser snapshot;

   public UserWithClaims(IdentityUser user, IReadOnlyList<Claim> claims, IReadOnlySet<string> roles)
   {
       // Clone the user so that we capture the previous values, even when the user is updated.
       snapshot = Mapper.IdentityUserToIdentityUser(user);
   }

   [Mapper(UseDeepCloning = true)]
   private static partial class Mapper
   {
       public static partial IdentityUser IdentityUserToIdentityUser(IdentityUser source);
   }
}

But the generated code does not add the namespace to the IUser interface, which is defined in another namespace. So the follow code is generated:

#nullable enable
namespace Notifo.Identity
{
    internal sealed class UserWithClaims : IUser
    {
        private static partial class Mapper
        {
            public static partial global::Microsoft.AspNetCore.Identity.IdentityUser IdentityUserToIdentityUser(global::Microsoft.AspNetCore.Identity.IdentityUser source)
            {
                var target = new global::Microsoft.AspNetCore.Identity.IdentityUser();
                target.Id = source.Id;
                ...
                return target;
            }
        }
    }
}

Expected behavior The implementing or base classes do not need to be copied to the generated code. if you want to copy that, add the namespaces.

Environment (please complete the following information):

• Mapperly Version: 2.8.0
• .NET Version: 7.0

Additional context Add any other context about the problem here.

Is it valid to map records defined like this?

public record Person(int Id, string Name, string Address); public record PersonDTO(int Id, string Name);

Yes! Afaik Mapperly can map most types.

Example

[Mapper]
public static partial class Mapper
{
    // MapperIgnoreSource isn't required but because `Address` is not mapped to the target Mapperly will generate a warning: "Source member "Address" not mapped".
    // by ignoring this member the warning will not be created
    [MapperIgnoreSource(nameof(Person.Address))]
    public static partial PersonDTO Map(Person src);
}

Generated code

public static partial global::Riok.Mapperly.Sample.PersonDTO Map(global::Riok.Mapperly.Sample.Person src)
{
    var target = new global::Riok.Mapperly.Sample.PersonDTO(src.Id, src.Name);
    return target;
}
