自动映射异常，尽管AssertConfigurationIsValid()成功

我真的很挠头。我已经从Automapper 2.2.1更新到3.1.1，代码在崩溃之前还能正常工作。我正在尝试获得更多的诊断信息来调试实际问题。

在单元测试中，我通过了，因为没有错误出现

[TestClass]
public class TestOldWcfEndpoint
{
    public TestContext TestContext { get; set; }
    bool FieldWasSpecified;
    [TestInitialize]
    public void TestInitialize()
    {
        AutoMapperUnity.RegistrationInUnitTesting();
        this.FieldWasSpecified = true;
    }
    [TestMethod]
    public void Test_OldWcfHosting_AutomapperConfigurationIsValid()
    {
        try
        {
            AutoMapper.Mapper.AssertConfigurationIsValid();
        }
        catch (AutoMapper.AutoMapperMappingException aex)
        {
            this.TestContext.WriteLine(aex.Message);
            throw;
        }
    }
}

AutoMapperUnity是一个静态帮助类，用于连接到Unity容器:

public static class AutoMapperUnity
{
    private static void Regsitrations()
    {
        Mapper.Reset();
        var business = new BusinessLogicMaps(); business.Configure();
        var api = new ApiServiceMaps(); api.Configure();
        var wcf = new OldWcfMaps(); wcf.Configure();
        Mapper.Configuration.AllowNullCollections = true;
    }
    public static void Registration(IUnityContainer container)
    {
        Regsitrations();
        container.RegisterType<IMappingEngine>(new InjectionFactory(_ => Mapper.Engine));
        container.RegisterType<IConfiguration>(new InjectionFactory(_ => Mapper.Configuration));
        container.RegisterType<IConfigurationProvider>(new InjectionFactory(_ => Mapper.Configuration));
    }
}

wcf地图出现了问题。Wcf端点构建在Web Api客户机使用的相同DTO契约之上。除了数据注释之外，Wcf契约是完全相同的。

public class OldWcfMaps
{
    void CreateMapForCodes()
    {
        Mapper.CreateMap<CodeTypeDTO, CodeTypeWcfDTO>()
            .ForMember(s => s.IDSpecified, o => o.Ignore());
        Mapper.CreateMap<CodeTypeWcfDTO, CodeTypeDTO>();
        Mapper.CreateMap<CodeDTO, CodeWcfDTO>()
            .ForMember(s => s.ActiveSpecified, o => o.Ignore())
            .ForMember(s => s.CodeTypeIDSpecified, o => o.Ignore())
            .ForMember(s => s.IDSpecified, o => o.Ignore());
        Mapper.CreateMap<CodeWcfDTO, CodeDTO>();
    }
    void CreateMapForCodeReports()
    {
        Mapper.CreateMap<CodeReportDTO, CodeReportWcfDTO>()
            .ForMember(s => s.ActiveSpecified, o => o.Ignore())
            .ForMember(s => s.AppIDSpecified, o => o.Ignore())
            .ForMember(s => s.IDSpecified, o => o.Ignore())
            .ForMember(s => s.CodeIDSpecified, o => o.Ignore())
        Mapper.CreateMap<CodeReportWcfDTO, CodeReportDTO>();
    }
    void CreateMapForShiftReports()
    {
        this.CreateMapForCodeReports();
        Mapper.CreateMap<ShiftReportDTO, ShiftReportWcfDTO>()
            .ForMember(s => s.NumberOfReportsSpecified, o => o.Ignore());
        Mapper.CreateMap<ShiftReportWcfDTO, ShiftReportDTO>();
    }
    public void Configure()        
    {
        this.CreateMapForCodes();
        this.CreateMapForShiftReports();
    }
}

}

[ServiceBehavior]
[AspNetCompatibilityRequirements(RequirementsMode = AspNetCompatibilityRequirementsMode.Required)]
public class TimeClockServices : ITimeClockServices
{
    /// <summary>
    /// Reference to the AutoMapper Engine.
    /// </summary>
    private readonly IMappingEngine MapperEngine;
    private readonly ILogFactory LogFactory;
    private readonly ITimeClockDataService TimeClockApi;
    public TimeClockServices(IMappingEngine mapper, ITimeClockDataService timeClockServices, ILogFactory logger)
    {
        this.MapperEngine = mapper;
        this.TimeClockApi = timeClockServices;
        this.LogFactory = logger;
    }
    public IEnumerable<CodeReportWcfDTO> GetCodeReports(ApplicationsEnum AppID, short DepartmentID, long CaseID, bool Active)
    {
        IEnumerable<CodeReportWcfDTO> groupOfWcfCodeReportDTOs = null;
        try
        {
            // Get Data using shared internal interface.
            IEnumerable<CodeReportDTO> codeReportDTOs =
                this.TimeClockApi.GetCodeReports(AppID, DepartmentID, CaseID, Active);
            // Convert the Data to the Wcf Extension Class.
            // **OFFENDING LINE**
            codeReportWcfDTOs =
                this.MapperEngine.Map<IEnumerable<CodeReportDTO>, IEnumerable<CodeReportWcfDTO>>(codeReportDTOs);
        }
        catch (BLException bex)
        {
            throw new FaultException<BLExceptionFault>(
                new BLExceptionFault("Business Engine Exception was thrown.", bex));
        }
        return codeReportWcfDTOs;
    }
}

这最终会导致错误:

Missing type map configuration or unsupported mapping.
Mapping types:
CodeReportDTO -> CodeReportWcfDTO
Api.Contract.Entities.CodeReportDTO -> Legacy.Contracts.WcfDTO.CodeReportWcfDTO
Destination path:
IEnumerable`1[0]
Source value:
Api.Contract.Entities.CodeReportDTO

只是上面我不知道它实际上是失败的，以更好地排除故障。DTO层也被映射到业务对象的等价物。
