Map Interface to concrete Type failed in v11.0.0

[mm-ryo]

Hi,
I want to map Entity1 to Entity1Map and TagData to TagData2.
the TagData2 is implemented IData2 you can see the mapping configuration below.
It works in v10.2.2 not in v11.0.0. I also tested it in 11.0.1-alpha.0.9. it doesn't work.

The Generic type mapping also changed in v11.0.0
I can do the below mapping for Generic type in v10

CreateMap(typeof(type1<>), typeof(type2<>));

but now I have to specify the type
CreateMap(typeof(type1), typeof(type1));

Source/destination types

Try to map Entity1 to Entity1Map

  var testService = new TestService();
  var entities = testService.GetEntity1s();
  var mapEntities = _mapper.Map<IEnumerable<Entity1Map>>(entities);

Mapping configuration

CreateMap<Entity1, Entity1Map>();
CreateMap<TagData, TagData2>();

Version: 11.0.0

Expected behavior

Should be able to map to target type

Actual behavior

Error mapping types.
Missing type map configuration or unsupported mapping.

Mapping types:
TagData -> IData2
Project1.TagData -> Project1.IData2

Destination Member:
Tags

Steps to reproduce

Framework: .net6
IDE: VS2022

I have attached a demo project
Project1.zip

1. Launch the project wait a moment and let it be ready
2. Click 'Fetch data' menu on the top right corner
3. Go to MapTestController and TestProfile to check codes for more info

That repro is too complicated. You need to make it like the example below.
Make a gist that we can execute and see fail.

Hi,
I converted the demo to the below codes.
I want to know whether we need to config something for Generic type and interface.

using AutoMapper;


var config = new MapperConfiguration(c =>
{
    c.CreateMap<Entity1, Entity1Map>();
    c.CreateMap<TagData, TagData2>();
});

config.AssertConfigurationIsValid();

var mapper = config.CreateMapper();


try
{

    var testService = new TestService();
    var entities = testService.GetEntity1s();
    var mapEntities = mapper.Map<IEnumerable<Entity1Map>>(entities);
}
catch (Exception ex)
{
    ex.ToString();
} 

public class Entity1Map
{
    public int Id { get; set; }
    public string Name { get; set; }
    public IData2 Tags { get; set; }
}

public class Entity1
{
    public int Id { get; set; }
    public string Name { get; set; }

    public TagData Tags { get; set; }
}

public class TagData
{
    public string Tag { get; set; }
}

public class TagData2 : IData2
{
    public string Tag { get; set; }
}

public interface IData2
{
}

public class TestService
{
    public IEnumerable<Entity1> GetEntity1s()
    {
        return new List<Entity1>
        {
            new Entity1
            {
                Id = 1,
                Name = "Entity1",
                Tags = new TagData
                {
                    Tag = "TestData"
                }
            }
        };
    }
}

You need

 cfg.CreateMap<TagData, TagData2>();
 cfg.CreateMap<TagData, IData2>().As<TagData2>();

But I don't see what generics have to do with this repro.

I didn't put it in demo. It's in our project. it works fine in v10.1.1. after I upgraded to the latest version it doesn't work anymore.
we didn't change any codes.

That doesn't mean much. If you can make a proper repro, I'll take a look.
