RecognizeDestinationPrefixes

[JezhikLaas]

Source/destination types

public class Source { public int Member { get; set; } }

public class Target { public int M_Member { get; set; } }

Mapping configuration

private static readonly MapperConfiguration Configuration = new(configuration =>
{
    configuration.CreateMap<Source, Target>().ForAllMembers(_ => configuration.RecognizeDestinationPrefixes("M_"));
});

Version: 12.0.0

Expected behavior

The following test used to work before 12.0.0. It fails now and I do not see anything related in the What's new.

Actual behavior

Mapping does not happen anymore

Steps to reproduce

[Fact]
public void ShouldUseDestinationPrefix()
{
    var mapper = Configuration.CreateMapper();
    var source = new Source { Member = 666 };
    var target = mapper.Map<Target>(source);

    target.M_Member.Should().Be(source.Member);
}

I'm afraid that this code doesn`t make much sense. Check our tests for proper usage. If it still doesn't work, I'll take a look.

I have checked your tests and realized that my usage of RecognizeDestinationPrefixes was wrong. Seems to have worked just by accident in the older releases.
Thanks, I have it working now.
