Question

我正在尝试在.Net Core 2.2上使用Auto Mapper。

配置：

services.AddAutoMapper(cfg =>
            {                                
                cfg.CreateMissingTypeMaps = false;                
                cfg.ReplaceMemberName("_", "");
                cfg.ShouldMapProperty = pi => pi.PropertyType != typeof(List<>);
                cfg.CreateMap<bool, string>().ConvertUsing(b => b ? "Y" : "N");
                cfg.CreateMap<string, bool>().ConvertUsing(s => s == "Y");
                cfg.CreateMap<NuCoreAppUser, APP_USER>()
                .ForMember(d => d.APP_USER_ID, opt => opt.MapFrom(src => src.Id))
                .ReverseMap();               
            };

这只是一个用于测试的映射。它在本地运行良好，但是在部署到Azure应用服务时会抛出：

ReflectionTypeLoadException: Unable to load one or more of the requested types.
 Could not load type 'System.Web.IHttpModule' from assembly 'System.Web, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a'.

Microsoft.AspNetCore.Hosting.Internal.WebHost.EnsureApplicationServices()
Microsoft.AspNetCore.Hosting.Internal.WebHost.Initialize()
Microsoft.AspNetCore.Hosting.Internal.WebHost.BuildApplication()

在我的应用程序中找不到任何引用System.Web的地方，也找不到限制Auto Mapper扫描该程序集的方法。

如果我删除了Auto Mapper，则一切正常部署。

自动映射器在System.Web.IHttpModule上引发ReflectionTypeLoadException
